Application: Single-acting cylinders.

Actuation: Solenoid operated, 115/230/24 volt, 50/60 Hz.

Function: Advances cylinder piston when solenoid is de-energized, and pump is running. When solenoid is energized, oil is directed back through valve “return” port and cylinder piston returns. To place cylinder in “hold” position, pump must be stopped or its flow held at the valve “pressure” port with the solenoid de-energized.

NOTE: Valve is equipped with a 9631 snubber valve in port “A.” The line from the “return” port of the valve must be unrestricted (100 psi back pressure maximum) back to the reservoir.

IMPORTANT: A 9580 in-line check valve must be installed in the “pressure” port if the supply pump is not equipped with an outlet check valve.

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.
