Product Detail
Function and configuration
The 4WRPEH type high-response valve is a pilot-operated directional control valve with electrical position feedback and integrated electronics (OBE).
The valves basically consists of the housing (1), spool (2), sleeve (3), control solenoid with position transducer (4) and so on.
The specified command value is compared with the actual position value in the integrated electronics (OBE). In the event of a control deviation, the stroke solenoid is activated, which adjusts the control spool against the spring due to the change in the magnetic force.
Lifting/control cross-section is proportionally regulated to the command value. In case of a command value presetting of 0V, 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.
Switch-off behavior
With the electronics switched off, the valve moves immediately into the relevant safe basic position (fail-safe). The switch position P–B/A–T is passed through during this process, which can result in movements on the controlled component. This must be taken into account in system.
