1. General information

The directional spool valves types PSLF and PSVF as well

as the individual sections type SLF serve to control both, the

direction of movement and the load-independent, stepless

velocity of the hydraulic consumers. In this way several

consumers may be moved simultaneously, independently

from each other at different velocity and pressure ratings, as

long as the sum of the partial flows needed for this is within

the total delivery supplied by the pump.

The proportional spool valves of this pamphlet are designed

as manifold mounting valves. They may be also combined

as valve banks via the sub-plates available from HAWE.

They consist of three functional groups.

There are two basic variations of connection blocks:

o Connection blocks with integrated 3-way flow controller, suitable for a fixed pump system (open-center) -type PSLF (see sect. 3.1.1)

o Connection blocks suited for a variable displacement pump system (closed center), a constant pressure systems, or if a

second or more separately located directional spool valve banks are fed in parallel - type PSVF (see sect. 3.1.2).

Temperature Ambient: approx. -40 ... +80°C; Fluid: -25 ... +80°C, pay attention to the viscosity range!

Start temperature down to -40°C are allowable (Pay attention to the viscosity range during start!),

as long as the operation temperature during consequent running is at least 20K (Kelvin) higher.

Biodegradable pressure fluids: Pay attention to manufacturer‘s information. With regard to the

compatibility with sealing materials do not exceed +70°C.

max

= 400 bar; Ports P, P1, A, B, LS, M, Y

The max. pressure achievable at the consumer side of the spool valves is lowered by the amount

equivalent to the internal control pressure drop at the 3-way flow regulator of the PSLF (see curves)

or at the pump flow regulator (PSVF)..

Return port R(R1) ≤ 50 bar; port T pressure less with separate pipe (e.g. 8x1) to the tank. It is

recommended to employ end plate E 1, E 2, E 3, etc. with an additional leakage port, in case

higher return pressure is anticipated. Port Z approx. 20 or 40 bar (acc. to coding, acc. to table 7)

(outlet); ≤ 40 bar (inlet)

For control pressure, see Q-I-characteristics. The internal control oil circuit is sufficiently

protected against malfunctions caused by contamination by means of a disk filter.

a) Connection block

There are, apart from the standard versions acc. to sect. 3.1.1

and 3.1.2. additional damping variations for the LS-signal

type PSV (coding S or B) duct listed in tables 2 or 4. These are

required, if strong (load-) oscillations are externally induced on

the control circuit. A general rule concerning the use of one or

other variation can however not given.

Coding G

This version lacks the sequence valve at the damping element

which is apparent at the standard version to enable quick

depressurization down to the pre-load pressure during idle

position of the valve spool. This results in a stronger damping

effect than with the standard version, as all fluid from the spring

cavity of the 3-way flow controller must pass the thread type

throttle. Main application is with consumers prone to low frequent

oscillations - drawback is the delayed depressurization down to

the pre-load pressure during idle position of the valve spool

(pro-longed run-down).

Coding H

If on account of the required consumer velocity at least one spool

valve with reference coding A 5 (raised circulation pressure) is

utilized, then, in order to maintain the necessary pressure

difference between 2- and 3-way flow controller, the circulation

pressure of the 3-way flow controller must be raised to approx.

14 bar. This means, of course, greater power dissipation.

Coding Z, ZM, V and PA, PB, PD (acc. to table 8)

When using these valves for an emergency stop function, it has

to be taken into account that there will be a certain min. residual

pressure during pushing load while a valve spool is elevated!

Viscosity $ 60 mm

b) Spool valve sections

Coding A 1 (example SLF 5-A 1 L 120/63...)

On the one hand, there is a higher consumer flow with

directional spool valves without an inflow controller (coding A 1)

in comparison with one having a 2-way flow controller (coding

A 2, A 5), as the flow is then directly dependent on the control

pressure of either the connection block‘s 3-way flow controller

(approx. 10 bar) in type PSLF, or the metering valve of a variable

displacement pump (approx. 14 to 20 bar), in type PSVF. On the

other hand, the load-independence is lost, if several consumers

are actuated simultaneously, because the consumer with the

highest load pressure rules the pressure level of the LS-signal

given to the 3-way flow controller and so defines the available

oil flow in the system.

When another valve with lower pressure is actuated now, the flow

can only be regulated by throttling, which means if the highest

load pressure varies, the spool elevation (= throttling) of the

second consumer has to be reset to maintain a constant delivery

flow to the consumer. This consumer flow can be calculated

approx. by (Q

A, B

= expected consumer flow, Q

nom

= rated

consumer flow for a valve with inflow controller coding A 2,

controller

= pressure difference at the flow controller of the

connection block or pump). Q

, Q

· 0.2 ·|p

controller

Coding A 2 (example SLF 5-A 2 0 63/80)

The standard version of the spool valve comes with load

compensation. Due to the control pressure of the inflow

controller (approx. 6 bar), it regulates a constant flow related

only to the spool elevation, making its delivery independent of

other consumers or system pressure Q , |p

controller

· A

valve spool

Coding A 26 and A 56 (example SLF A-326 J 40/25...)

Symptoms of resonance (audible knocking of the 2-way flow

controllers) can be sometimes caused if pulsating consumers

e.g. radial or axial piston motors with a low number of pistons)

are connected.

This is prevented by use of a restrictor check valve combination

which delays the closing of the inflow controller. This doesn‘t

harm the characteristic of the functional cut-off or the pressure

limiting valves.

Coding A 5 (example SLF 5-A 5 J 160/160)

This version has an increased control pressure enabling high-

er consumer flows (see also above coding A 1 and A 2). The

pressure of the flow controller is 10 bar resulting in a 1.3 higher

flow compared to the standard version (coding A 2).

Coding A 7 (example SLF 5-A 7 H 160/160)

Like coding A 5, due to the necessary pressure drop only in

combination variable displacement pump / constant pressure

system i.e. basically type PSVF.

Coding A 8 (example SLF 3-A 8 L 80/63...)

To ensure max. flow for all subsequent valve sections, the high-

est flow rating (80/... or 160/...) must be selected for the A side

(continuation of P).

Coding AR 2, AR 5 and AR 7

The flow controller acts additionally like a check valve. Thus

preventing a reversal of the flow direction in case of starving

pump delivery.

Coding AA 9 (example SLF 5-AA 9 H 160/160)

Like coding A 5. This version has an increased control pressure

enabling higher consumer flows. Only suited for variable

displacement pump / constant presusre systems i.e. only suited

for PSVF.

The valve body is optimized for higher flow i.e. this controller

cannot be used with standard valve bodies.

Symbols

Flow pattern symbol P, A, T, Q, K (only size 3)

These spools show positive overlap. Type P overlaps in both

switching directions, i.e. during elevation of the spool the con-

nection P d A(B) is opened before of connection B(A) d R.

This results in an undesired pressure intensification at cylinders

(area ration . 1), therefore we recommend type A, T, Q or K as

these have a one-sided overlapping only. They are intended for

consumers such as hydro-motors / double acting cylinders (area

ratio 1:1) with righting moments / -forces, as well as at cylinders

with drawing loads (area ratio . 1). A short-term preloading

prevents „lowering jolts“ and „running empty“. These valve

spools can substitute load-holding valves to a limited extent. It

should be taken into account, that a short-term working against

the max. system pressure takes place.

The flow coding for A should be selected higher than for B with

spool codings A and T to prevent unintended pressure intensifi-

cations (for spool codings Q and K Q

c) Flow-pattern variations

Flow pattern symbol J, B, R, O and I, Y, Z, V

Oscillations may occur depending on application during start

(e.g. winches) or during normal operation (e.g. crane booms).

They can be caused by the natural frequency of the hydraulic

motors or external load variations e.g. swinging load. The flow

coding (table 15) of the respective spool should correspond to

the cylinder ratio as far as possible.

Flow pattern symbol W

This 4/2-way directional spool valve is intended for applications

where a constant velocity is required e.g. blower or generator

drives. The ability of prop. speed control is restricted, but load

independency is ensured via the inflow controller (table 13).

o Therefore only usable at open center systems (type PSLF)

pressure approx. 11 bar

o The flow while lowering is only throttled (no flow control

functionality) and therefore load-dependent. It is therefore

necessary (safety!) to limit the drop rate by a drop rate braking

of the valve spool (suffix to the types A, C, EA, HA, HEA, PA

acc. to sect. 3.2.1 tables 20 and 21 and sect. 4.3)

Maritime ambient climate

The aggressive sea atmosphere requires sufficient corrosion

protection of all moving part of the actuations with hand lever.

The actuation shaft in the hand lever housing is therefore made

of stainless steel as standard. All other parts are either corrosion

inhibiting gas nitrided or made of stainless steel.

Exception: Housing of pneumatic actuation P or PA which is

made of anodized light alloy.

Pressure surges in the return line

Minor leakage may appear at the spring domes of actuations

type AS, CS, E, EAS and E0AS when excessive pressure peaks

(>150 bar) do occur in the return line. This can be prevented

by use of enforcement flanges (suffix G acc. to table 21

in sect. 3.2.1).

Note: The perm. pressure in the return line is limited to approx.

50 bar (see sect. 4.1). The functionality of the actuation

solenoids could be harmed in case of excessive pressure.

e) Use of variable displacement pumps

With Load-sensing controls in alliance with variable displace-

ment pumps, the LS-signal duct for the pump pressure-flow

controller (Load-Sensing metering valve) is relieved, to minimize

circulation losses during idle position (no consumer flow ). This

limiting takes place via the proportional spool valves. Without this

decompression the pump would have to work during no-lift

position with all the remaining flow against the pressure set at the

safety valve of the pressure regulator.

As there exist spool valves without this limiting possibility,

some brands of pressure-flow controllers have a internal

bypass orifice or throttle between LS-signal entrance and

decompressed leakage outlet.

In case of the prop. spool valves type PSVF this is not necessary

and can even cause malfunctions due to lost control oil. The

control oil flow is for functional reasons consciously limited

(approx. 2 lpm) (slow-motion of the consumer).

Note: Care must therefore be taken, to ensure that a possible

bypass orifice in the pressure-flow regulator is plugged!

f) Combination with load-holding valves

It can happen due to exterior variations of load and resonance

that the control system starts to oscillate, if three regulation

devices, the 3-way flow controller in the pump or the connection

block, the 2-way flow controller at the spool valve section plus

load holding insert are connected in series. This can be effectively

suppressed by systematic use of a bypass orifice and throttle-,

check-, pre-load valve combination within the control oil circuit

at the load-holding valve type LHDV acc. to D 7770. A similar

behavior can be achieved with use of the over-center valves

type LHT acc. to D 7918.

g) Combination of more than 12 spool valves

Through the consecutive connection of the LS-signal duct, a

total of max. 12 spool valves can be linked. Whether the spool

valves are arranged in one or more valve banks is irrelevant. This

restriction results from the only limited available oil flow (ensu-

ring slow-motion movements). If more than 12 spool valves in

separated directional spool valve banks are to be coupled via the

LS-signal, a chaining via external shuttle valves is to be used.

i) Indications of actuation HEA

The following notes to the connection of the valve bank have

to be observed to ensure a flawless function of the electric and

hydraulic actuation.

Combination with hydraulic control devices similar

(circuitry acc. to example 1)

Examples 1

Combination with common hydraulic joy-sticks or

hydraulic control devices type FB and KFB acc. to D 6600

and D 6600-01 (circuitry acc. to example 2)

The pressure reducing valves integrated in the joy-sticks open

the consumer line to the tank during idle position. The control oil

flow would escape via this bypass when a valve is simultaneously

solenoid actuated. Therefore it is a must to provide check valves

for the control lines at this kind of circuitry. The same applies to

hydraulic actuations. The used throttles however limit the bypass

leakage. The control oil supply must be dimensioned so that

this leakage can be compensated (> 0.7 lpm per actuated valve

section plus the internal leakage of the hydraulic joy-stick).

6.3.4 Notes on changing the spool

The valve spools are not mated to one spool housing.

Therefore valve spools can be changed at any time to adapt

to changing consumer consumption.

The following routine is to be followed particularly:

Advice on changing the valve spool

1. Slacken screws ; (ISO 4762-M5x8-8.8-A2K), remove

spring cover

2. Remove screw < (M 6x40, machined flat head screw

drawing No. 7709 042)

3. Remove spring assembly including spring cap =

4. Slacken screws > (ISO 4762-M5x50-8.8-A2K)

5. Lift lever housing including spool out of spool housing,

drawing ? @

6. Remove circlip DIN 6799 3,2 and remove bolt A B

7. Assemble with (new) spool in reverse sequence

Attention: The control grooves of the valve spool should

always be installed towards the end plate!

Exception: Valve spools with flow coding 80

(size 3) and 160 (size 5) do not show

control grooves.

Indications for angling the lever housing by 180°

(inversion of the shifting mode)

As set out in 1. - 7. above, however instead of a new

valve spool the existing one has to be disconnected, angled

at 180° and remounted (see above mentioned note). The

intermediate plate C together with the lever housing, have

to be angled at 180°.

All lever housings of the valve bank have to be rotated!
