Altitude Control valve (ACV-900)

The NU-TECH Altitude Control valve is designed to control the water level in tanks or elevated storage reservoirs without use of floats or sensors.

  • 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.
  • Valves equipped with separate adjustable opening and closing speed controls

  • One way valve: It is designed to open & allowing into tank & close drip tight when water level is achieved.
  • Two way valve: it is designed to open & allowing into tank & close drip tight when water level is achieved. This valve also opens & allows return flow when inlet pressure is lower than tank head pressure.
  • Monitors tank head pressure through a field-installed sensing line that opens for tank fill and closes at the desired level

  • One way flow with pressure sustaining.
  • One way & two way flow with delay open for return flow.
  • One way & two way flow with solenoid

  • Accurate shut-off to within inches of set point
  • Automatic tank fill and shut-off without the use of floats or sensors
  • Minimum pressure loss.
  • High level point adjustable with single screw.
