Screw-in cartridge proportional pressure reducing valve, direct acting. The valve maintains the constant
pressure in the applicator pipeline (A-port) proportional to the input command signal. When the applicator is
overloaded, the circuit is connected to the tank (T-port) and protected against pressure overloading (relieving
function of the valve).

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).
