The type 2FRE proportional flow control valves have a 2-way function. They can, from an applied electrical command value, regulate a flow which is pressure and to a great extent temperature compensated. They basically comprise of the housing, proportional solenoid with inductive position transducer, measuring orifice, pressure compensator, stroke limiter, as well as an optional check valve. The setting of the flow is determined (0 bis 100 %) at the command value potentiometer. The applied command value, causes via the amplifier as well as the proportional solenoid, the adjustment of the measurement orifice. The position of the measurement orifice is obtained by the position transducer. Any deviations from the command value are compensated for by the position feedback control.
