For Use With

PA17*, PA46*, PA55, PE17*, PE21*, PE30, PE46*, PE55, PE60, PE84, PE120, PE200, PE400, PG30*, PG55, PG120, PG400, PQ60 and PQ120 series. * These pumps may have reduced first flow stage characteristics due to internal valve restrictions.

Operation

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 6,400 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.
