Enhanced surface protection for mobile sector available for the steel parts (ISO 9227, 520 h salt spray)

Functional Description

A direct-operated, spool-type hydraulic pressure reducing-relieving valve in the form of a screw-in cartridge.
Reduced pressure in output (A) is proportional to DC current input. When the appliance is overloaded, the
circuit is protected against damage by high pressure by connecting it to the tank (channel T).
Note: Consult factory for special OEM versions of this product.

 Elektronic control unit EL7

An electronic control unit (ECU) EL7 is used for the valve control. The ECU converts the input command signal into an output current control PWM
signal for solenoid coils. The ECU EL7 is available as external for connection to the DIN rail (EL7-E, see datasheet HA 9152) or integrated on the valve
in the form of connector plug (EL7-I, see datasheet HA 9151).
