Spreader Valves Technical Information
SPR-2FFL12
OPERATION
This is a compensated spreader valve with dual ow regulation and manual dump for an open circuit gear pump application. This is a direct replacement to the 2FFL12.
APPLICATIONS
The valve maintains constant regulated ow to two actuators even with changes in load pressure or input ow. The pressure-compensated regulating section bypasses excess pump ow 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 lever-operated two-way valve dumps system ow to tank, allowing on/o control of both regulated ows without changing either ow 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 motor movement potential.

Spreader Valves Technical Information
SPR-2FFLC12
OPERATION
This is a compensated spreader valve with dual ow regulation and manual dump for an open circuit piston pump application. This is a direct replacement to the 2FFLC12
APPLICATIONS
For use with variable displacement pressure compensated pumps in load sensing circuits that require two pressure compensated ow controls. The integral lever allows on/o pump control. This valve is designed for speed control of two actuators which must have individual ow settings. The LS port senses the load pressure on both actuators to signal the pump to increase or decrease the supply ow. With the lever in the unload position, no load is sensed and the pump de-strokes.

SPR-2FFLW86
OPERATION
This is a compensated spreader valve with dual ow regulation and solenoid dump for an open circuit gear pump application. This is a direct replacement to the 2FFLW86.
APPLICATIONS
For use with xed displacement pumps in circuits that require two pressure compensated ow controls, solenoid valve for on-o dump and pump relief. The valve maintains constant regulated ow to two actuators even with changes in load pressure or input ow. The pressure-compensated regulating section bypasses excess pump ow 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 ow to tank. This allows on-o control of both regulated ows without changing either ow 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.
