Spreader Valves Technical Information
SPR-2FFL12
OPERATION
This is a compensated spreader valve with dual flow 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 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 lever-operated two-way valve |
|
|
dumps system flow to tank, allowing 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 motor movement potential. |
