| Describe |
| Proportional flow control valves of type 2FRE … feature a 2- way function. They can control a flow, which is determined by an electrical command value, in a pressure- and largely temperature-compensated way. |
| They basically consist of housing, proportional solenoid with inductive position transducer, metering orifice, pressure compensator, stroke limiter and check valve. The setting of the flow is determined by the setting (0 to 100 %) on the command value potentiometer. The selected command value causes metering orifice to be adjusted via the amplifier and the proportional solenoid. The inductive position transducer senses the position of metering orifice. Any deviations from the command value are corrected by the closed-loop position control. |
