4WRPEH6C3B02L-2X/G24K0/A1M 4/4-way NG6 / CETOP 3 servo solenoid directional control valve, directly operated, with electrical position feedback and on-board electronics (OBE). 2 litres a minute. 7 Pin connection +/- 10V

4WRPEH are direct operated directional control valve 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 

• Control solenoid with position transducer 

• On-board electronics (OBE) 

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 un-tensioned to a maximum and the valve is in fail-safe position.
