Product Parameters

 

 

Function, section
Valves of type 4WRPEH are direct operated directional
control valves with electrical position feedback and
integrated electronics (OBE).
Set-up
The 4WRPEH high-response valve mainly consists of:
Valve housing with control spool and sleeve in servo
quality (1)
Control solenoid with position transducer (2)
(optionally with electronics protection membrane (5))
On-board electronics (OBE) (3) with analog or IO-Link
interface (4) (optionally with damping plate (6))

Function
The integrated electronics (OBE) compares the specified
command value to the position actual value. In case of
control deviations, the stroke solenoid will be activated.
Due to the changed solenoid force, the control spool is
adjusted against the spring. Stroke/control spool
cross-section is controlled proportionally to the command
value. In case of a command value presetting of 0, the
electronics adjusts the control spool against the spring to
central position. In deactivated condition, the spring is
untensioned to a maximum and the valve is in fail-safe
position.

Control solenoid shut-off
In case of the following errors, the control solenoids are
de-energized by the integrated electronics (OBE) and the
control spool is set to fail-safe position:
Falling below the minimum supply voltage
