Operation

 


This is a compensated spreader valve with dual flow regulation and solenoid dump for an open circuit gear pump application. This is a direct replacement to the 2FFLW86.

Applications


For use with fixed displacement pumps in circuits that require two pressure compensated flow controls, solenoid valve for on-off dump and pump relief. The valve maintains constant regulated flow to two actuators even with changes in load pressure or input flow. The pressure-compensated regulating section bypasses excess pump flow to tank. The pump operates at the highest load pressure plus control section pressure drop. The tank or bypass port must be referenced directly to tank and not to a working line. The direct acting relief valve senses system pressure and protects the pump from shock or overload pressure surges. The built-in, solenoid-operated, two-way valve unloads system flow to tank. This allows on-off control of both regulated flows without changing either flow setting. In the unload condition an 8.6 bar [125 psi] check valve may be required in either the A port, the S port or both ports to reduce the potential of motor movement.
