Flow Control valve

NU-TECH Flow Control Valves are designed to limit flow rate to an adjustable maximum.

  • Easily maintained without removal from the line.
  • Replaceable seat ring.
  • Heavy-duty, nylon-reinforced diaphragm.
  • Operates automatically off line pressure.
  • Used at water distribution system
  • Used at filter backwash control.
  • Diaphragm assembly Guided top and bottom.

  • It is designed to control or limit flow to a constant, predetermined rate regardless of fluctuation in upstream and downstream pressure.
  • Differential pressure across the orifice plate is less than the pilot setting , the valve remains open.
  • The pilot and main valve remain closed until manually reset.
  • It protecting against a break in the downstream pipe
  • Senses differential pressure across a factory-calibrated orifice plate, then accurately throttles to maintain field-adjustable flow rate
  • Orifice plate can be installed downstream or upstream, making it ideal for pressurized pipeline or open reservoir water-blending applications

  • Solenoid (On-Off)
  • Pressure reducing
  • Hydraulic check
  • Pressure sustaining
