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.

Applications:
• Line Fill-Up Control Solutions.
• Line Emptying Prevention.
• Systems Subject to Varying Supply Pressures.
• Infield Filters and Backwash Pressure Sustaining.
