QVMZO are double proportional valves, which provide the indipendent flow and pressure control in systems with fixed displacement pump, according to the electronic reference signal.
They operate in association with electronic drivers, see sect. 7, which supply the proportional valves with correct current signal to align valve regulation to the reference signal supplied to the electronic driver.
The cartridge regulates the flow at port A according to the reference signal Q.
The cartridge operates as 3-way pressure compensator between P and A ports discharging excess flow through port T.
The pressure is regulated according to the reference signal P.
The pressure relief valve with manual setting operates as safety valve. The coils are fully plastic encapsulated (insulation class H) and valves have antivibration, antishock and weatherproof features.
