FEATURES

* Load independent flow control corresponds to the

spool-position proportional to the electrical input

signal.

* The pump pressure always corresponds to the user

pressure, +3,6,8 or 12 bar (43, 86, 114 or 172 psi)

∆p compensator.

* The built-in pump-unloading valve results in:

- very low power turned into heat;

- minimum loading of the prime mover.

* User speed is precisely controlled under all load

conditions.

* Progressive regulating curve; no pressure peaks

when switching; sensitive control even for

alternating pressures.

* Constant working speed of differential cylinders at

the different regulating flow to the valve by grinding

angle.

* Constant recirculation pressure independent of the

number of units.

* Any limiting of flow for every user port.

* Load independent switching adjustment, constant

acceleration and deceleration.

* Proportional solenoids with longer life for the

armature in the oil (explosion proof solenoids “II 2 EEx

mII T4 or T5”, available).

* Proportional directional control valves also

available as:

- Manual proportional series MHV and

- Hydraulic proportional series MOV.

Any combination of these control options is

possible.

* The sub plate system allows a construction up to

8 control valves.

DESCRIPTION

Conventional directional control valves control start, stop and directions of movement from hydraulic motors

and cylinders. However, the speed of these users depends on the load pressure. If this load pressure varies,

the speed is hardly controllable (figure 1)

The AMCA proportional directional control valves are pressure compensated and achieve an ideal control of

force, speed, acceleration and deceleration, independent of the load and increased demands (figure 2)

The pressure compensator could be a pressure relief valve (MUV) or a pressure reducing valve (MDM), together

with the throttling function of one or more directional control valve spools. This compensator acts as a by-pass

(3-way) flow control valve (with MUV) or as series (2-way) flow control valve (with MDM).

See figures 3 and 4.

Advantages of the AMCA Proportional Directional Control Valves:

The shape of the AMCA proportional directional control valve spool differs from the conventional one.

The result is a progressive flow curve (figure 5). To make optimal use of the maximum stroke of the spool the

flow angles of the A and/or B port can be defined for the different flows. For a constant flow, the pressuredrop

over the orifice of the spool remains constant, independent of the load pressure (figure 6).

Functioning of the by-pass (3-way) flow control

valve (with MUV)

(this type is used in combination with fixed

displacement pumps) (fig. 7 and 8)

The AMCA-MUV has three functions:

1. Energy saving

If the directional control spools are in neutral position

(spool 1 in fig.7), and the pump is running, the

pressure relief valve 1 (MUV) opens at low pressure

(depending on the spring 3, 6, 8 or 12 bar (43, 86,

114 or 172 psi)).

P and T are connected. The power (pxq

) turned into

heat is very low.

The spring chamber is connected, via the “load-

pressure check back system”, to T (tank).

(example fig. 21)

2. Load independent flow control

(acting as a 3-way flow control valve)

If one directional control spool is actuated (spool 2

in fig. 7, where P is connected to B2), the load-

pressure is connected to the spring chamber of the

MUV. The left part of the “load pressure check back

system” is closed by spool 2. The load-pressure

added to the spring-equivalent pressure is in balance

with the pressure at P. Therefore the ∆p over the

directional control valve remains constant (3, 6, 8 or

12 bar (43, 86, 114 or 172 psi)).

As q

= k. ∆p, the flow remains constant, at a given

opening of port B2, independent of the load-pressure.

The output (flow) is proportional to the input signal

(displacement of spool).

The unnecessary pumpflow returns to tank.

3. Adjustable maximum load pressure

The maximum load-pressure can be restricted by the

adjustable relief valve 2.

Functioning of the series (2-way) flow control

valve (with MDM)

(this type is used in combination with variable

displacement/pressure compensated pumps

(example fig. 9 and 10) or accumulator circuits.

The AMCA-MDM has three functions:

1. Energy saving

If the directional control spools are in neutral position

(spool 1 in fig. 9) and the pump is running, the

pressure reducing valve MDM (normally open) tends

OPERATION

to close (is balancing).

The pressure controls the pump-capacity to a

minimum. Again the power (p x q

) turned into heat

is very low.

The spring chamber is connected, via the “load-

pressure check back system” to T (tank).

2. Load independent flow control

(acting as a 2-way flow control valve)

If one directional control spool is actuated (spool 2

in fig. 9) MDM-orifice throttles the flow and reduces

the pressure. This reduced pressure is connected to

B2.

The left part of the “load pressure check back system”

is closed by spool 2. The load pressure added to the

spring-equivalent pressure (3, 6, 8 or 12 bar (43, 86,

114 or 172 psi)) is in balance with the reduced

pressure.

Therefore the ∆p at flow angle 2 remains constant

(3, 6, 8 or 12 bar (42, 86, 114 or 172 psi)). As q

k. ∆p, the flow remains constant at a given opening

of port B2, independent of the load pressure.

The output (flow) is proportional to the input signal

(displacement of spool).

There is no unnecessary pumpflow (pump capacity

is controlled by pressure).

3. Adjustable maximum load pressure

The maximum load pressure can be restricted by

the adjustable relief valve 2.

Functioning of the by-pass (3-way) flow control

valve (with MUV/R)

(this type is used if there is a need to use the MUV

as a sequence valve)

(fig. 11 and 12)

The function is the same as described in clause 1

(fig. 7). The return bore is blocked (as in fig. 9). There

is an additional possibility of directing the pumpflow

from P to R (fig. 12) to feed another circuit up to 350

bar, or to control the adjusting mechanism on a

variable displacement pump (fig. 11).

(example fig. 24)

Note: (1)

If the systempump is of the load sensing type,

no compensator is required. (example fig.25)

(2)

For simultanious operation of the proportional

directional control valve, independent of

loadpressure, we advice a pressure

compensator for each control valve.

For flows < 201 l/min. (53 USgpm) per control

section, the MFC stacked valves are a good

alternative in this case. (see Publ. F12/18K)

OPERATION

Functioning of the proportional directional control valve with electrically controlled pilot stage. (MEV)

(Fig. 13, 14 and 15)

When solenoid a is actuated it pushes the pilot spool towards solenoid b and opens throttle position 1.

This allows pilot pressure to the springchamber 1 (speed controlled by the adjustable restriction 5) and also

through bore 3 to the end of the pilot spool opposite to solenoid a.

The balance force on the pilot spool is the force of the solenoid which is proportional to the electric input.

The balance force equates the pilot pressure in solenoid b and also in springchamber 1.

This pressure pushes the main spool against the spring in springchamber 2 and thus takes up a position

proportional to the electric input signal.

With the screws on the springchambers the maximum flow can be adjust by turning in the screw and block the

main spool in his stroke.

CONFIGURATION

TYPE OF VALVE MOUNTING

The AMCA proportional directional control valves series MEV...A are sub-plate-, multiple sub-plate- and ganged

sub-plate valves. A complete AMCA-MEV..A system consists for example of three main parts (fig 16)

1. MUV or MDM :pressure relief (fig 17) or

pressure reducing valve (fig 18)).

2. MEV :4/3 directional control valve with

electrically controlled pilot stage.

3. Ganged sub-plates :including inlet- and endplate

OPTIONS

The following options are possible (see fig 19,

application (example) and ordering code).

Port connections:

T2 :

Low back pressure.

- if a MUV-valve is mounted, T2 is normally

plugged in the subplate, or

- if there are cylinders in the circuit with a large

returnflow, T2 shall be connected to tank for a

lower return pressure in the valve, or

- if a MDM-valve is mounted on the subplate,

T2 is the mainport to tank.

T3 : External pilot drain (on the pilot stage).

- is neccesary if the backpressure in the

returnline rises continually above 6 bar, for

example a spring loaded check valve in the

returnline between T connection of the valve

and the tank connection,

- T3 is a pilotdrain and has to be drained to tank

seperately.

X: Auxiliary port (on inlet subplate).

- the maximum pressure-level in the entire

system can be remotely controlled by the use

of a small relief valve (size 4 mm (0.16 inch))

connected to the auxiliary port X, or

- the pressure in the entire system can be

unloaded by the use of an electrically operated

2/2 valve connected to aux. port X (e.g. for

load security systems on mobile cranes), or

- in case of a load sensing system, the load

pressure check back signal on the X port can

be connected to the load sense port of the

variable displacement pump.

X2 : External pilot supply (on the pilot stage).

- if, due to very light loads, the pump pressure

does not rise up to 12 bar (172 psi) during a

part of the cycle, the pilot stage shall be fed

by an external pilot supply source.

Y: Auxiliary port (on the directional control

subplate).

- if it is necessary that one or more users in a

circuit operate at reduced pressure, a small

relief valve (size 4 mm (0.16 inch)) may be

connected to port Y.

Z:Auxiliary port (on the directional control

subplate).

- if valves are combined (with the same or

different size), port Z is used, or

- for sensing the load pressure check back

signal, this port shall be connected to port X of

the next valve, which requires only a simple

inlet plate AN (see ordering code).

is optional

VARIANTS/OPTIONS

The following variants/options are possible (see

ordering code, page 26 and 28).

Compensator (MUV/MDM) variants:

Recirculation pressure:

V : Adjustment 6...12 bar (86...172 psi). The

spring in the spring chamber is adjustable

between 6 and 12 bar (86 and 172 psi) for

exact control of the max. flow on users A

and B of the proportional directional control

valve. (see page 26)

Max. pressure adjustments variants:

H : With handwheel (Ø 30mm, Ø 1.18inch) for

manual adjustment without using tools

E2 : Electrical remote control up to 350 bar (5000

psi)

W : Without pressure adjustment, no relief valve.

Options:

Q : Normally, MUV spools have no connection

between the P bore and the spring chamber.

In certain cases, a small orifice (0,6 mm) to

provide a “positive feed in” is desirable. As

an example: for multi-section blocks.

P : Normally, MDM spools are mounted with a

small orifice, to connect the reduced pressure

to the spring chamber for quick response. If

one or more MDM valves are connected to a

load sensing pump, option P (plugged MDM-

spool) is recommended.

Electrical control system:

N : No proportional control, on/off

F : Proportional control

Spool types:

A,B,C,D,E,F,G,K,M,O : See page 2

Flow:

.../... : Flow port A/port B in litres/minute, the choice

has to be made in combination with the ∆p of

the compensator (MUV or MDM). For the

maximum flow per ∆p compensator see page

Note: the control valve is standard equiped

with stroke limitation screws in the spring

caps, if the flow of a port is adjusted with this

screw, the electrical input signal has a shorter

bandwidth.

Options:

ACS : Adjustable Centering Springs on the main

spool, if the users A and B should have

exactly the same flow in combination with the

same current on solenoids a and b.

G : Cast iron spring caps. If the standard

aluminium caps are not suitable for the

environment conditions. (for instance sea-

water resistance)

JS : Additional connection for hydraulical control,

with shuttle valves and restriction for external

pilot control e.g., through pilot pressure

devices.

M : Additional manual control, a second control

possibility in addition to the electrical control.

(manual override)

MSW : As option M, suitable for special environment

conditions like seawater. (the springcap is also

in cast iron)

N : Neutral spool position signal, through inductive

switch.

Solenoid types:

A : 12 VDC IP65 with emergency control by pin

B : 24 VDC IP65 with emergency control by pin

(standard)

E : 12 VDC IP65 with emergency control by

button

F : 24 VDC IP65 with emergency control by

See note on page 4.

Parallel circuit with fixed displacement pump

Two valve blocks using only one pressure compensator (MUV).

By connecting port X (the load pressure signal) of the second control block (AN..A) to port Z of the first control

block (A..EV/Z), the MUV creates a load independent flow control for both valve-blocks (not for simultaneous

operation).

Series circuit with fixed displacement pump

With the subplate A..UV/R there is an additional possibility of directing the pumpflow from P to R in order to feed

another circuit.

Note: - Connecting T2 of the subplate A..UV/R must always be connected to tank.

- Not for simultaneous operation.

MIN. ∆P LS-PUMP 6 bar (86 psi)

Load independent flow control by using load sensing pump. (No AMCA compensator: AN)

If the hydraulic system is equiped with a load sensing pump, the X port of the inlet plate AN..A has to be

connected with the load sensing signal-port of the LS-pump. A pressure compensator MUV or MDM is not

necessary in that case.

Note: If ordering the control valves (MEV) the ∆p of the pump has to be specified, so the spools can be grinded

for the ordered flow.

MAINTENANCE DATA

Mounting procedure

- AMCA-valves shall not be mounted by

overtightening of mounting bolts, causing

mechanical distortion and thus spool lock. (see

tightening torques).

- Mounting on flat surface, flatness

0,01/100 mm

(0.0004/3.9 inch).

- Don’t use conical thread for port-fittings.

- For sealing purposes, use O-rings.

- At the port-connections at the sub-plates, the B-

port shall be connected to the line with the largest

return-flow (e.g. piston-side of differential cylinder),

because in the valve the distance B-T is shorter

than A-T.

- Check the voltage and current of the solenoids,

before operation.

- Avoid ingression of contaminants during mounting.

Start-up procedure

- Start the system-flushing procedure with the

adjustment-screw of relief valve (see fig. 29-31,

(1) on page 22) fully released to achieve the

minimum pressure.

- Turning the adjustment-screw clockwise (360 turn

= ca. 100 bar (143 psi)), the maximum load-pressure

rises up to the desired level. (max. 350 bar (5000

psi)). During this adjustment the end-users (cylinder

and/or motor) should be blocked.

- Check the valve-function and the tightness of

fittings etc.

- Use the stroke limiting screws to bleed the end-

caps, during system bleeding.

Adjustment procedure

MDM/MUV

To avoid instability of the MDM- or MUV-spool, the

damping-screw (see fig. 32, (2) on page 22) is factory-

setted. Adjustment on location is possible as follows:

- Remove the cover-screw (width 5 mm (0.2 inch))

- Adjust the damping with the damping-screw (width

5 mm (0.2 inch)), turning clockwise or anti-

clockwise for more or less throttling.

Note: Don’t throttle too much especially in the case

of MDM otherwise the load signal can be disturbed.

Valve response time

The valve response time is adjustable from 0,24 -

10 seconds. Adjustment screws are on the pilot stage

below the solenoids.

- Turn the adjustment screws clockwise to enlarge

valve response time.

- Turn the adjustment screws anti-clockwise to

shorten valve response time.

Flow-adjustment

Factory-setting of flows, as ordered in ordering code.

If, after long life-cycle, re-adjustment should be

necessary, two possibilities are available, depending

on the configuration:

1. Stroke limiter (see fig. 33, (5) on page 22)

- Remove cover-screw of stroke limiter

- Loosen the lock-nut (width 13 mm (0.51 inch))

- Turn the stroke limiting screw (width 4 mm (0.16

inch)) clockwise to reduce flow and anti-clockwise

to enlarge flow.

2. ∆p adjustment (see page 26)

- Loosen the lock-nut (width 13 mm (0.51 inch))

- Turn the adjustment screw (width 4 mm (0.16 inch))

clockwise to enlarge the preset spring-force, to

achieve more flow. (anti-clockwise to reduce flow)

- Tighten lock-nut.

Note: If the flow through A-port is sufficient and

the flow through B-port should be enlarged, adjust

first the B-flow by

∆

p-adjustment and reduce after

that the A-flow by stroke limitation.

Fluid maintenance

Due to the construction, these AMCA-valves, are

not highly susceptible to particulate (silt type) lock,

nor to contaminant wear. Therefore the contaminant

sensitivity is very low.

- Use mineral oil (recommended ISO/VG-32). Other

fluids on request.

- Keep the contamination level better or equal NAS

1638 class 9 or ISO 18/15.

TROUBLE SHOOTING

A. System pressure too low or set pressure

cannot be reached

1. Relief valve cartridge fouled

Dirt particles jammed between cone and seat of

relief valve (1) and prevent pressure being built

up.

Turn adjustment anti-clock wise, switch a

directional valve several times. If necessary,

dismantle (a M4 bolt assists in removing the

springcup). If damaged, replace cone and seat.

Examine the system filter.

2. Damping throttle (2) blocked (dirt or

maladjustment).

If necessary, remove, clean and replace.

Adjust to 1 1/2 - 2 1/2 turns from fully closed

position. Find the right damping position. Turn the

throttle only by unloaded pump.

3. MUV-spool (3) or MDM-spool (3A) jammed open

When removing lower end-cover (4) the spring

should push out of the spool. Remove and

examine the spool and bore for damage. Deburr

with care. Flush the spool to remove dirt.

4. Faults in other components of the system

Damaged pump, motor, seals etc.

Note: The set pressure can only be reached if a

cylinder is at the end of its stroke or a motor

is stalled.

B. User moves erratically

1. Air in system

Bleed both end-caps with stroke limiting screws

(5).

Slacken bolts (6) fixing the solenoids to body and

retighten after repeated operation.

2. Pilot valve faulty

Fit a pressure gauge in place of the stroke limiting

screws to observe pilot pressure.

If persistent, swap pilot stage (7) to another

section to detect faulty unit.

3. Excessive friction of directional spool

Remove both end-caps (8) and examine spool

(9) and bore from dirt or damage. Deburr with care.

Examine system filter.

Also spool lock, when mounting faces are not

flat.

4. Excessive damping

See B2.

5. Excessive friction in other components of the

system

C. User does not move or moves at slow speed

1. Damping throttle blocked or dirty

See A2.

2. Relief valve setting too low

See A1.

3. Directional spool does not shift

See B3.

4. MUV or MDM-spool jammed open

See A3.

5. There is insufficient user load.

6. Filter in returnline is contaminated.

D. Pump does not unload

1. MUV-spool jammed (see A3)

2. Directional spool not centring

Excessive friction (see B3).

Electrical fault. Check the electrical circuit.
