10000 psi, 3/8" ports, 5 gpm max flow rate.
Application: Single strand, single acting stressing jacks with Power Wedge seater.
Actuation: Lever operated, detent positioned.
Used on these pumps: PA17 (These pumps may have reduced first flow stage characteristics due to internal valve restrictions.), PA46 (These pumps may have reduced first flow stage characteristics due to internal valve restrictions.), PA55, PE17 (These pumps may have reduced first flow stage characteristics due to internal valve restrictions.), PE21 (These pumps may have reduced first flow stage characteristics due to internal valve restrictions.), PE30, PE46 (These pumps may have reduced first flow stage characteristics due to internal valve restrictions.), PE55, PE60, PE84, PE120, PE200, PE400, PG30 (These pumps may have reduced first flow stage characteristics due to internal valve restrictions.), PG55, PG120, PG400, PQ60 and PQ120 series.
To prevent sudden, uncontrolled descent of a load as it is being lowered, use a No. 9596 Load Lowering Valve or No. 9720 Counter Balance Valve in conjunction with the directional valve used in your application. Conversion kit 251528 must be used when mounting any of the valves on PA17 or PE17 pumps.

N/A 1.With valve in center position, pump is started.
2. Cable is inserted into stressing tool, valve is placed in “A” position. “Pull” portion of stressing tool is pressurized to specified level for proper cable tensioning (“A” port is checked internally, can only be released by building pressure in “B” position).
3. Valve is placed in “B” position, which is pressure controlled and will not exceed 6400 psi. “Return” portion of stressing tool is pressurized and will release “A” port when pressure reaches approximately one half the “A” port pressure. “A” port remains open as long as this pressure differential is maintained.
4. Pump is stopped, valve is placed in “A” position, releasing “B” port pressure.
