1. General

The directional spool valves types PSL and PSV serve to

control both, the direction of movement and the load-inde-

pendent, 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 valve banks and consist of three functional

groups:

The high control pressure of variable displacement pump controllers may lead to unintentional

movements of consumers with low load pressure even while the respective valve is in its idle

position. The pump gallery is completely blocked with type PSV 5 N to ensure a definitive

separation of pump and consumer circuit. This takes place by means of a solenoid valve. The

LS-gallery together with the LS-controller may be additionally relieved via a separate 2/2-way

directional seated valve.

Brief description

The shut-off valve can arbitrarily block the

pump gallery for all subsequent consumers.

The switching signal can be either hydrauli-

cally (/H) or electrical (/E). The connection to

all subsequent valve sections can be either

open (S) or blocked (V) if not actuated.

The main application is with circuits where it

is necessary to lock (block) one or more con-

sumers due to functional or safety reasons.

”Connection block PSL” on next page) or at the pump flow regulator (PSV). Return port R(R1)

Ò 50 bar; port T pressureless 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 bar (acc. to coding, see table 7) (outlet); Ò 40 bar (inlet)

a) The connection block

There are additional damping variations available for the LS-

signal duct listed in table 2 (apart from the standard versions acc.

to sect. 3.1.1). These are required, if strong (load-) oscillations

are externally induced on the control circuit. However, a general

rule concerning the use of the one or the other variation can not

be given. Both versions may be retrofitted any time.

To coding U (or UH)

The pump idle circulation pressure is reduced by means of an

additional by-pass valve, if all directional spool valves are in idle

position (see also curves in sect. 4.2). The valve opens automa-

tically if the occurring load pressure (LS pressure) drops below

25% of the (still remaining) pump pressure.

Attention: A minimum pump delivery flow of approx. 150 lpm

must be maintained for electro-hydraulic actuation

with internal control oil supply. The control pressu-

re (& pump circulation pressure) is not sufficient for

elevating the spool at lower delivery flows.

To coding Y and YH

Additional, pressure resistant port F for the excess oil from the

3-way flow controller. This enables to control separately located

consumers by making use of the excess delivery flow not con-

sumed by the prop. directional spool valve bank.

It is important that the pressure induced via port F is minimum

15 bar lower than the load pressure applied to the 3-way flow

controller of the first valve bank, if a consumer connected to this

valve bank is simultaneously operated. Otherwise the LS control

system will fail, and the excess flow might be forced via the main

pressure limiting valve.

To 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 posi-

tion 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).

To coding H

When on account of the required consumer velocity at least one

spool valve with reference number 5 (raised circulation pressu-

re) is utilized, then, in order to maintain the necessary pressure

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

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

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

To coding Z, ZM, V and PA, PB, PD (see 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!

b) Spool valve sections

To coding 1 (example SL 5-51 L 120/63...)

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

spool valves without an inflow controller (coding 1) in compari-

son with one having a 2-way flow controller (coding 2, 5), as the

flow is then directly dependent on the control pressure of either

the connection block‘s 3-way flow controller (type PSL approx.

10 bar), or the metering valve of a variable displacement pump

(approx. 14 to 20 bar) for type PSV. On the other hand, the load-

independence is lost, if several consumers are actuated simulta-

neously, because the consumer with the highest load pressure

rules the pressure level of the LS-signal given to the 3-way flow

controller and therefore defines the available flow in the system.

As soon as another valve with higher load pressure is actuated

now, the flow for the first consumer can only be regulated by

throttling, i.e. if the highest load pressure varies, the spool elevati-

on (= throttling) of the first valve section has to be reset to maintain

a constant delivery flow to the consumer. This consumer flow can

be calculated approximately by:

A, B

, Q

nom

· 0.2 ·|p

controller

To coding 2 (example SL 5-52 0 63/63...)

The standard version of the spool valve section is load compen-

sated and is equipped with an inflow controller (coding 2). Due

to the control pressure of the inflow controller (approx. 6 bar), it

regulates a constant flow related only to the spool elevation

(groove edges at the spool act like a metering orifice), making

its delivery independent of other consumers or system pressure:

Q , |p

controller

· A

valve spool

To coding 5 (example SL 5-A 5 H 160/160...)

This version features an increased control pressure enabling

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

pressure of this flow controller (coding 5) is approx. 10 bar resul-

ting in a 1.3 higher flow when compared to the standard version

(coding 2).

To coding 7 (example SL 5-A 7 H 160/160)

Like coding 5. To be used only together with variable displace-

ment with connection block type PSV and variable displacement

pump / constant pressure system because of the necessary

pressure drop.

To coding R 2, R 5 and R 7

Beside its control function the flow controller acts also as a

check valve. Thus preventing a possible flow reversal in case of

insufficient supply from the pump.

To coding 8, 81, 82 (example SL 5-58 L 120/160...)

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

highest flow rating (.../160) must be selected for the B side

(continuation of P).

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).

Flow pattern symbol G

3-position 3-way-spool for single acting cylinder

Restrictions:

o No LS-Signal while lowering

o Therefore only usable at open center systems (type PSL) and

electric actuation with restrictions – idle pump circulation

pressure approx. 11 bar

o The lowering function is just a throttle valve function (load

dependent lowering speed). The system needs to be protected

by a separate flow control valve (to limit the max. speed e.g.

with type SB acc. to D 6920).

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

when excessive pressure peaks do occur in the return line

(during rapid on/off of consumers). 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

Load-sensing controls in alliance with variable displacement

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 decompres-

sion 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 PSV 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 de-

vices, 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 10 spool valves

A total of max. 10 spool valves can be linked, via a consecu-

tive connection of the LS-signal duct. It is irrelevant, whether

the spool valves are arranged in one or more valve banks. This

restriction is caused by the limited oil flow being available

(ensuring slow-motion movements). A chaining via external shut-

tle valves is to be used, if more than 10 spool valves in separated

directional spool valve banks are to be coupled via the LS-signal.

h) Mechanical 2-axis joy-stick

Two neighboring valve sections (functions) can be simultan-

eously actuated via hand lever

Order coding: PSL 51/250 - 5

- 52 L 160/80/K

- 52 H 80/63/K

- 52 L 120/63/A-E 1

(It is possible to combine this mechanical 2-axis joy-stick with

electro.-hydraulic actuation)

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 like type FB and

KFB acc. to D 6600 and D 6600-01

These control devices can be directly connected, due to their

function and low inner leakage.

Combination with common hydraulic joy-sticks

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 actuation. 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).

All installation, set-up, maintenance and repairs must be

performed by authorized and trained staff. The use of this

product beyond the specified performance limits, use of non

specified fluids and/or use of not genuine spares will cause

the expiration of the guarantee.

6.3.1 Mounting

The mounting of the valve bank must be performed in such

a way that no stress is induced.

Three screws and elastic washers between valve assembly

and frame are recommended for fastening.

6.3.2 Piping

All fittings used must utilize deformable seal materials.

Do not exceed the specified torque!

6.3.3 Notes for converting the connection block

The connection blocks type PSL 5(6)...-5 and PSL UNF 6..-5

can be converted any time into a connection block for varia-

ble displacement pump systems (correct type then PSV 55

S../..-5 or PSV UNF 6 S). This requires replacing the parts

listed below.

Attention: The screw (parts No. 6380 013)

D Dor carburetor

jet M4x0.6 E Eare secured with liquid screw lock,

which must be applied again when replacing these

parts.

This conversion cannot be carried out at the

type PSL 5(6) U(H) and PSL 6 Y since the inte-

grated valve combination forbids a combination

with variable displacement pump systems.

It is necessary to replace the tapped plug by

the damping screw S F (7778 301), while

converting a type PSV to type PSL (does not

apply to type PSV 5(6) S..-5 and PSV UNF 6 S..-5;

as these are already equipped with it).

6.3.4 Notes on changing the spool

The valve spools are not mated to one spool housing. The

refore 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-M6x8-8.8-A2K), remove

spring cover

2. Remove screw < (M8x40, machined flat head screw

drawing DIN 7991)

3. Remove spring assembly including spring cap =

4. Slacken screws > (ISO 4762-M6x60-8.8-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

Note: The control grooves of the valve spool should

always be installed towards the end plate!

Exception: Valve spools with flow coding 160 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 inter-

mediate plate

C together with the lever housing, have to be

angled at 180°.

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