Application – Single or double-acting cylinders.

Actuation – Lever operated, detent positioned.

Functions – Pos. 1 – Oil is directed to “advance” side of cylinder, oil from “retract” side goes to reservoir; cylinder “holds” with pump shut off. Pos. 2 – Oil goes to “retract” side of cylinder; cylinder “holds” with pump shut off. When using as a 3-way valve for single-acting cylinders, port “A” or “B” is plugged.

Used on these pumps – P460, PA6D, PA17, PA46, PA55, PA60, PE17, PE21, PE30, PE46, PE55, PE84, PE90, PE120, PE200, PE400, PQ60 and PQ120 series.

NOTE: 9504 can be remote mounted with a 9510 Subplates.

NOTE: A Pressure Switch and/or Gauge (Analog or Digital) may be attached to this valve.

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.

IMPORTANT: Conversion kit 251528 must be used when mounting any of the valves on PA17 or PE17 pumps.

IMPORTANT: When ordering any valve for a PE30 or PG30 series pump, ½” longer mounting screws are required.
For valves 9504, 9584, 9610 and 9610A, order four 12001 cap screws.
For valve 9582, order two 12001 and two 10856 cap screws.

NOTE: Valves 9501, 9502, 9504 and 9507 can have a port blocked or have a closed center position. When a port is blocked and the valve is shifted to the blocked port, the pump will generate excessive heat. An electric or rotary air pump can either be turned off manually or with a pressure switch. Reciprocating air pumps may be adjusted to stall out and stop.

NOTE: Gauge ports monitor pump pressure only, not pressure to the hydraulic cylinder(s).
