Pressure pmax = 400 bar (6000 psi)Flow Qmax = 210 lpm (55 gpm)

The directional spool valves types PSL and PSVserve to control both, the direction of movement and the load-independent, stepless velocity of thehydraulic consumers. In this way several consumersmay be moved simultaneously, independently fromeach other at different velocity and pressure ratings,as long as the sum of the partial flows needed for thisis within the total delivery supplied by the pump. The proportional spool valves of this pamphlet aredesigned as valve banks and consist of three func-tional groups:

Table 13: Spool valve; basic unit

Coding Basis for max. consumer oil flow

Standard, with inflow controller, for simultaneous load compensated movementof several consumers.

Without inflow controller intended for singularly / successively actuated functions. Ifmore valve sections are actuated, only the one acting against the highest load pres-sure will move proportional to the spool elevation. Additional functions on the con-sumer side are not possible. The max. consumer flow depends on the 3-way flow con-troller in the connection block. For the max. flow of the indiv. section, see table 13.

With inflow controller (for symbol see coding 2) but with reinforced spring at the 2-way flow controller (control pressure approx. 9 bar). Can be used only together withconnection block type PSL.U(Y)H../...-5- or type PSV fed by a variable displacementpump / constant pressure system. See also note in sect. 7.1a.

The max. pressure achievable a t 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 PSL (see curves)or at the pump controller (PSV). Return ports R(R1) are rated ≤ 20 bar (50 bar with enforced springhousing, table 21. It is recommended to employ end plate E1, E2, E3, etc. with an additional leak-age port, in case return pressure > 20 bar is anticipated.

Example 1:

D 7700-5 page 28

a) The connection block

There are additional damping variations available for the LS-signal duct (type PSV, coding S or B) listed in table 2 and 5 (apartfrom the standard versions acc. to sect. 3.1.1 and 3.1.2). These are required, if strong (load-) oscillations are externally inducedon the control circuit. However, a general rule concerning the use of the one or the other variation can not be given.

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 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 typethrottle. Main application is with consumers prone to low-frequent oscillations - drawback is the delayed depressurization downto 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 pressure) isutilized, then, in order to maintain the necessary pressure difference between 2- and 3-way flow controller, the circulation pressure ofthe 3-way flow controller must be raised to approx. 14 bar. This means, of course, greater power dissipation.

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 idleposition (see also curves in sect. 4.2). The valve opens automatically if the occurring load pressure (LS pressure) drops below25% 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 pressure (& pump circulation pressure) is not sufficient for elevating the spool at lower deliv-ery flows. Load pressure must be min. 20 bar.

To coding UH

The control pressure of the 3-way flow controller must be raised by approx. 15 bar to ensure a pressure difference between 2- and 3-way flow controller if at least one directional spool valve coding 5 (increased circulation pressure) is used due to the required consumer velocity. An increased dissipation power of the control system is obliged with this. The by-pass valve (seecoding U) is therefore integrated as standard to minimize pressure losses during idle pump circulation.

To coding Y, 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 consumed by the prop. directional spool valve bank. When connecting two valve banks type PSL in series, it is necessary to employ version YH for the first one to maintain a sufficient pressure drop required for a flawless control function.

b) To the spool valve sections

To coding 1 (example SL5-51 L 120/63...)On the one hand, there is a higher consumer flow with directional spool valves without an inflow controller (coding 1) in compar-ison with one having a 2-way flow controller (coding 2, 5), as the flow is then directly dependent on the control pressure of eitherthe 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 simul-taneously, because the consumer with the highest load pressure rules the pressure level of the LS-signal given to the 3-way flowcontroller and therefore defines the available flow in the system. As soon as another valve with higher load pressure is actuatednow, the flow for the first consumer can only be regulated by throttling, i.e. if the highest load pressure varies, the spool elevation(= throttling) of the first valve section has to be reset to maintain a constant delivery flow to the consumer. This consumer flow canbe calculated approximately by:

To coding 2 (example SL5-52 0 63/63...)The standard version of the spool valve section is load compensated and is equipped with an inflow controller (coding 2). Due tothe 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:

To coding 5 (example SL5-55 H 160/80...)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. 9 bar resulting in a 1.25 higher flow when compared to the standard version (coding 2).It makes only sense to use this version for flow codings higher than 160, as a higher control pressure causes higher losses aswell!

c) Variations for special operation conditions or requirements

Operation at potentially explosive areas

Variation: - Hydraulic actuation (type H, HA or HEA) - Pneumatic actuation (type P or PA)- Electro-hydraulic actuation (type E and EA) in a explosion-proof version, conforming EEX m II T4.

Order coding: G 24ex (see also section 4.3)

Maritime ambient climate

The aggressive sea atmosphere requires sufficient corrosion protection of all moving part of the actuations with hand lever. Theactuation 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 ofanodized light alloy).

D 7700-5 page 29

Pressure surges in the return duct

A return pressure of approx. 50 bar is approved (see sect. 4.1). At higher return pressure no guarantee for the reliability of the actuation solenoids can be given!.

d) Use of variable displacement pumps

With Load-sensing controls in alliance with variable displacement pumps, the LS-signal duct for the pump pressure/flowcontroller (Load-Sensing metering valve) is relieved, to minimize circulation losses during idle position (no consumer flow ). Thisrelieve takes place via the proportional spool valve sections. 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 without this decompression.As there exist spool valves without this limiting possibility at the market, some brands of pressure/flow controllers feature aninternal 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 loss of control oil. The control oil flow is consciously limited (approx. 2 lpm) for functional reasons (slow-motion of the consumer).Attention: Care must therefore be taken, to ensure that a possible bypass orifice in the pressure/flow regulator is plugged!Example: Pressure/flow regulator of manufacturer Mannesmann Rexroth, Brueninghaus Hydraulik; Type DFR1 (orifice plugged)should be used instead of type DFR (with orifice).

e) 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 of the pump or the connection block, the 2-way flow controller at the spool valve section andthe load holding insert are connected in series. This can be effectively suppressed by systematic use of a bypass orifice and acombination of throttle, check valve and pre-load valve within the control oil circuit at the load-holding valve type LHDV acc. toD 7770. A similar behavior can be achieved with over center valves type LHT acc. to D 7918.

f) Combination of more than 10 spool valves

A total of max. 10 spool valves can be linked, via a consecutive connection of the LS-signal duct. It is irrelevant, whether the spoolvalves 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 shuttle valves is to be used, if more than 10 spool valves in separated directionalspool valve banks are to be coupled via the LS-signal.

g) Flow pattern symbol variants

Flow pattern symbol J, B, R, O, and I, Y, ZOscillations may occur depending on application during start (e.g. winches) or during normal operation (e.g. crane booms). Theycan 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.

Notes on changing the valve spool

1. Slacken screws ; (ISO 4762-M6x8-8.8-A2K), remove spring cover

2. Remove screw < (M 6x40, flat head screw 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 lock washer DIN 6799-3.2 and bolt AB7. Assemble with (new) spool in reverse sequence

Note: The control grooves of the valve spool always have to direct towards the end plate (installed state)Exeption: Valve spools with flow coding 160 do not have control grooves.

Indications for angling the lever housing by 180° (inversion of the shifting mode)

As set out in points 1 to 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°.

7.4 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 variable displacement pump systems (correct type then PSV 5(6) S../..-5 or PSV UNF6 S). This requires replacing the parts listed below.

Attention: The screw (part No. 6380 013) D or SOLEX carburetor jet M4x0.6 E are secured with Loctite. Loctite (or similar) must

be applied again when replacing these parts.

This conversion cannot be carried out at the type PSL 5(6) U(H) and PSL 6Y since the integrated valve combination forbids a combination with variable displacement pump systems.

It is necessary to replace the tapped plug by the damping screw (7778 301) F, while converting a type PSV to type PSL (does not

apply to type PSV 5(6)S..-5 and PSV UNF 6S..-5; as these are already equipped with it).

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.

b) Combination with common hydraulic joy-sticks

The pressure reducing valves integrated in the joy-sticks openthe consumer line to the tank during idle position. The control oilflow would escape via this bypass when a valve is simultaneouslyactuated via the solenoid. Therefore it is a must to provide checkvalves for the control lines at this kind of circuitry. The same ap-plies to hydraulic actuation. The used throttles however limit thebypass leakage. The control oil supply must be dimensioned sothat this leakage can be compensated (> 0.7 lpm per actuatedvalve section plus the internal leakage of the hydraulic joy-stick).
