Pressure compensated flow controls Model 2FRM are two-way restrictive-style flow regulators. They accurately control flow, independent of changes in fluid viscosity or pressure drop across the valve. This valve maintains a constant actuator speed independent of changes in load-induced pressure. Sharp edged throttle openings reduce the influence of flow variations from temperature change.

DFR – Pressure and flow control
In addition to the pressure control function, the pump flow may be varied by means of a differential pressure over an orifice or valve spool installed in the service line to the actuator. The pump flow is equal to the actual required flow by the actuator, regardless of changing pressure levels. The pressure control overrides the flow control function.
This direct acting, solenoid-operated, 4-way, 3-position spool valve is spring centered to the neutral position. When coil A is energized, the flow is from port 3 (P) to port 2 (A) and from port 4 (B) to port 1 (T). When coil B is energized, the flow is from port 3 to port 4 and from port 2 to port 1.
