Pressure Compensated Adjustable Flow Control Valve

Changes in flow rates are achieved by mechanically varying the spring force acting on a spool that has a fixed orifice and metering compensator.

Pressure compensated adjustable flow control valve.

This pressure compensated adjustable flow control valve maintains a constant flow rate out of port 1 regardless of load pressure changes in the circuit downstream of port 1 as shown by the performance graphs plotting pressure drop from port 2 to port 1 across the valve versus flow rate through the valve. The fr08 30f is a screw in cartridge style pressure compensated non adjustable hydraulic flow regulator valve. Or a restrictive type 2 way flow regulator when the bypass port 2 is blocked. J02e2 j04c2 and j04e2 are fully adjustable pressure compensated flow regulators.

The excess flow port is not a work port and must be returned to tank. These valves can operate with hydraulic system flows as high as 56 lpm and pressures up to 420 bar with the option of an integrated adjustable or tuneable reverse free flow check valve. Once the controlled flow demand is satisfied the compensator spool shifts and passes any excess flow to the excess flow port. Eaton flow control valves precisely factor in the temperature pressure and volume of flow for efficient handling of each application.

The lefc performance as a flow control is very similar to the large fc51 because they both use the same spring and compensator spool. The brand lefc large electronically adjustable proportional pressure compensated flow control is an electronically controlled version of the original large fc51 style flow control valve. One the adjustable pressure compensated controlled flow and the other excess flow which over and above the controlled flow. Whether the hydraulic system requires integrated relief screw in cartridge valves pressure compensation or a more specific combination of features eaton can provide the perfect fit.

Parker s pressure compensated flow control valves are ideal for cylinder or motor control and or bleed off applications within a broad range of markets such. In the opposite flow direction those valves only meter through a fixed orifice and do not compensate.
