POD : MULTI-TURN /QUARTER TURN VALVES

General Information

  • Data Acquisition System for Test Records of Quarter Turn and Multi Turn Valves.
  •  Measurement of opening time, closing time, Dwell time at full open condition. Dwell time measurement at full close condition. Measurement of linear travel distance of valve stem.
  • Display of no of cycles
  • Adjustable forward and reverse speeds for opening/closing of valve.
  • Measurement of torque during valve opening and closing at various angular position, different line pressure.
  • Counter memory will be retained at the time of sudden power failure.
  • Different models can be built up to suit different size and torque requirement.
  • Prefilling pump ( optional ) for prefilling the valve before test
  • Hydraulic Driven/ Air driven pump for high pressure built up of water.
  • Pressure release solenoid / pneumatic actuated valve
  • Suitable for angle flanged stop valve, straight way valve, straight way union, offset straight way union and other quarter turn valves
  • High precision pressure sensor for line pressure measurement.
  • The present model is suitable for 10 to 100 Nm / 5 to 25 RPM
  • Graphs / trends can be plotted for followings :
  • Torque v/s percentage opening at a fixed line pressure
  • Torque v/s line pressure
