Non-Interflow Manual Valves

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: A Pressure Switch and/or Gauge (Analog or Digital) may be attached if desired. 
NOTE: Also, valve may be remote mounted with a 9510 Subplates. 
CAUTION: To prevent sudden, uncontrolled descent of a load as it is being lowered, use a Load Lowering Valve (No. 9596) orCounter Balance Valve (No. 9720) in conjunction with the directional valve used in your application. 
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 generated 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). 
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 9502 and 9520, order four 12001 cap screws. 
For valve 9576, order four 17428 cap screws.
