Application: Single or double-acting cylinders.

Actuation: 9593, 9524 and 9554 are solenoid 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.

不E: When using more than one valve on a pump, the tank port may require a check valve (9580) to permit inadvertent, momentary extension of a retracted cylinder.

不E: If pump is equipped with an internal outlet check, a "hold" position can be maintained with the pump shut off.

不E: 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).

不E: Valves have 1/4" NPTF ports. 3/8" to "1/4" adapters are included.

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

不E: 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.
