QVHMZO and QVKMZOR are proportional valves, direct operated, which provide indipendent pressure and 3-way compensated flow controls according to the electronic reference signals.
They operate in association with electronic drivers, see section 8 which supply the proportional valves with correct current signal to align valve regulation to the reference signal supplied to the electronic driver.
The flow is controlled by a throttle , directly operated by the proportional solenoid . The mechanical pressure compensator keeps a constant Delta p across the throttle , thus the regulated flow is independent to the load conditions.
The exceeding flow is returned to tank through the port P.
The pressure is controlled by the compensator , piloted by the proportional pressure relief valve .
The coils are fully plastic encapsulated (insulation class H) and valves have antivibration, antishock and weather-proof features.
