FUNCTION
The P4WR 6 is a direct acting
solenoid valve which combines the
directional control with the velocity
control of the consumer.
The controlled nominal flow is
proportional to the electrical input
signal at the coil.
Analogue to his size the coil creates
a force and moves the piston
against the spring. Herewith the
corresponding cross section
diameters are opened which
determines the flow rate in
dependence of the pressure
differential.
For the electrical control of the
valve there are electronic modules
available (see brochure 5.249.0
PEK-WAR).
