Application:For systems using large cylinders or extended lengths of hydraulic hose.

Operation:Controls surges by restricting flow if it exceeds 7 gpm. When flow subsides, valve reopens automatically. Has 3/8" NPTF male end to thread into return port of system control valve, and a 3/8" NPTF female end, permitting return hose to be directly connected.

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, 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).

3-WAY/3-POSITION (CLOSED CENTER) NON-INTERFLOW MANUAL VALVE WITH POSI-CHECK

Application Single-acting cylinders.

Actuation Lever operated, detent positioned.

Functions Pos. 1 Oil is directed from pump to cylinder and holds with pump shut off; line to reservoir is blocked. Pos. 2 All oil is open to reservoir through tank line.

Center pos. Cylinder pressure is held; pump should be shut off.

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

10, 000 PSI., 3/8" PORTS, 5 GPM MAX FLOW RATE.

NOTE:APressure Switchand/or Gauge (AnalogorDigital) may be attachedif desired.

NOTE:Also, valve may be remote mounted with a9510 Subplates.

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

4-WAY/3-POSITION (CLOSED CENTER) MANUAL VALVEApplication Single or double-acting cylinders.

Actuation Lever operated, detent positioned.

FunctionsAdvance, hold and return. Closed center design makes valve suitable for operating multiple cylinders from a single pump.

Used on these pumps P460, PA17, PA46, PA55, PA60, PE17, PE21, PE30, PE46, PE55, PE84, PE90, PE120, PE200, PE400, PQ60 and P120 series.

10, 000 PSI., 3/8" PORTS, 5 GPM MAX FLOW RATE.

NOTE:APressure Switchand/or Gauge (AnalogorDigital) may be attached to valves 9500, 9501, 9506, 9511 if desired.

NOTE:Also, valves may be remote mounted with a9510 Subplates.

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

Application:Provide an economical means of protecting an hydraulic circuit against over pressurization.

Operation:These factory preset valves are designed for maximum flow rate of 5 gpm. Furnished with 1/8" NPTF male port. All valves weigh 0.2 lb. See chart in 'Specifications'for ordering information.

NOTE: Care should be exercised to protect workers from hot, pressurized hydraulic oil. Install these valves only in an enclosed or shielded area.
