SPX Power Team 9632 Post-Tensioning Valve for Double-Acting Systems

SPX Power Team, 9632, Post-Tensioning Valve for 10,000 PSI Double-Acting Systems

Features:

• Applications: Multi-strand, double-acting stressing jacks with an auxiliary seating cylinder.
• Actuation: Dual lever-operated, detent-positioned.
• Operation:
  • With valves "A" and "B" in center position, pump is started, and cable is inserted into stressing tool.
  • Valve "A" is placed in "Stress" position and cylinder extends to tension cable. Pump pressure controls force exerted by tensioning cylinder in this position. "Stress" port is checked internally, and can only be released by building pressure in the valve "B" return position.
  • When desired cable tension is achieved, valve "A" is placed in valve "B" position and valve "B" in "Seat" position. Seating portion of cylinder will be pressurized to seating pressure controlled by "Seat" relief valve (factory set to 3,900 psi).
  • Valve "B" is shifted to "Return" position, which is pressure controlled and will not exceed 2,200 psi. "Return" portion of stressing tool should be pressurized and will release "Stress" port when pressure reaches 15% of "Stress" port pressure.
  • "Stress" port will remain open and cylinder will return as long as pressure differential is maintained. "Stress" and "Seat" ports are open to reservoir.
  • When cylinder has fully returned, both valves are shifted to "Center" position and oil will be directed to reservoir. Maximum pressure setting for the "Seat" relief valve is 6,000 psi.
• Used on these pumps: PA17*, PA46*, PA55, PE17*, PE21*, PE30, PE46*, PE55, PE120, PE400, PG30*, PG55, PG120, PG400, PQ60 and PQ120 series.

Note: These pumps may have reduced first flow stage characteristics due to internal valve restrictions.
