Pressure Relief/Sustaining valve (ACV-201)

NU-TECH ACV Pressure Relief/Sustaining Valves operates when inlet pressure is above the set point, and throttle when pressure is below the field-adjustable set point. The valve will be in closed position if upstream pressure drops below the set point and will fully open when the upstream pressure exceeds the set point.

  • Easily maintained without removal from the line.
  • Replaceable seat ring.
  • Heavy-duty
  • nylon-reinforced diaphragm.
  • Operates automatically off line pressure.
  • Diaphragm assembly Guided top and bottom.

  • Closed under normal operating pressures.
  • Valves opens when pressure rises to the set point
  • Valves will close when system pressure drops below set point.
