Pressure Sustaining Valve

100 – SERIES
    Features and Benefits:
  • Pressure Sustaining Valve is a hydraulically operated, diaphragm actuated control valve that sustains minimum preset upstream (back) pressure and opens fully when line pressure is in excess of the setting.
  • Unitized flexible super travel (FST) diaphragm and guided plug:
    a) Accurate and stable regulation with smooth closing.
    b) Requires low opening and actuation pressure.
    c) Prevents diaphragm erosion and distortion.
  • Ultra – high flow capacity – low pressure loss.
  • User friendly design simple in-line inspection and service.
  • Engineered plastic valve with industrial grade design.
  • Highly durable, chemical and cavitation resistant, no internal bolts and nuts.
  • Line Fill-Up Control Solutions.
  • Line Emptying Prevention.
  • Systems Subject to Varying Supply Pressures.
  • Infield Filters and Backwash Pressure Sustaining.
