Function, sectional diagram

Construction

The valve consists of three main assemblies:

– Pilot valve (1) with control spool and sleeve, return springs,

control solenoid and inductive position transducer

– Main stage (2) with centering springs and position feedback

– On-board trigger electronics (3)

Power failure

In the event of a power failure or an open circuit, the

on-board electronics cut off the electricity to the control

solenoid and the pilot spool moves to the fail-safe position,

relieving the control oil chambers of the main stage.

The main stage control spool is held by springs in the offset

position.

Functional description

When the control solenoid is not actuated, the control

spool is held by springs in the fail-safe position, and the

main stage spool remains in spring-centered offset position

at 1…6 % of the stroke in the direction P-B/A-T.

In the on-board electronics, the pre-defined setpoint is

compared with the actual value for the position of the main

stage control spool. In the event of an error signal, the

control solenoid is actuated, and the pilot spool is moved

as the magnetic force changes. The flow released through

the control cross-sections causes the main control spool to

move. The stroke/control cross-section of the main control

spool is controlled proportionately to the setpoint. If the input

setpoint is 0 V, the electronics move the main stage control

spool to mid position.

The control oil is conveyed to the pilot valve either internally

via port P or externally via port X. The oil returns to the tank

internally via port T or externally via port Y.

Control oil supply

Important

Hydraulic symbols are largely derived from the symbols

of the switching valves. 4/3-way servo solenoid directional

control valves (pilot operated) do not have a closed mid

position when switched off! They only perform their function

in an active, closed control loop, even if the pilot valve

features a fail-safe 4th position. See technical data for

details on “switch-off behavior”.

Important

Pilot operated 4/3-way servo solenoid directional control

valves only perform their function in an active closed control

loop and do not have a fail-safe position when switched off.

For this reason, many applications require the use of

“external check valves”, which must be taken into account

during the On/Off switching sequence.
