Application: Single or double-acting cylinders; air operated (minimum of 50 psi air pressure required.)

Actuation: 9595 is air operated.

Operation with single-acting cylinder: Either oil port « A » or « B » must be plugged on valve. With port « B » plugged, solenoid is energized to position « A, » oil port « A » becomes pressurized. When solenoid is energized to position « B, » oil port « A » becomes the return port.

Operation with multiple single-acting cylinders: A pressure line from one bank can be connected to oil port « A » and the other to oil port « B » on the valve. Sequence: When energized to position « A, » oil port « A » becomes pressurized and clamps the fixture connected to oil port « A »; oil port « B » becomes a « return » port for cylinder connected to oil port « B, » and retracts it. The opposite happens when solenoid « B » is energized.

Operation with double-acting cylinder: Port « A » is connected to « advance » port of cylinder, oil port « B » connects to cylinder « return » port. Solenoid is energized to position « A, » oil port « A » becomes pressurized to extend cylinder piston. The opposite happens when solenoid « B » is energized. Valve does not hold in « retract » position.

NOTE: When using more than one valve on a pump, the tank port may require a check valve to permit inadvertent, momentary extension of a retracted cylinder.

NOTE: If pump is equipped with an internal outlet check, a « hold » position can be maintained with the pump shut off.

NOTE: Valves are shipped without control switch.
For valves 9524, 9554 and 9593, use Remote Hand Control (No. 304718).
For valve 9595, use Remote Hand Control (No. 209593).

NOTE: Valves have 1/4″ NPTF ports. 3/8″ to « 1/4″ adapters are included.

NOTE: Maximum tank line pressure for remote mounted valves is 500 psi.

NOTE: Valves are shipped without control switch. Use Remote Hand Control (No. 202777).

CAUTION: To prevent sudden, uncontrolled descent of a load as it is being lowered, use a Load Lowering Valve (No. 9596) or Counter Balance Valve (No. 9720) in conjunction with the directional valve used in your application.
