Control valve, one way altitude level/constant flow, for drinking water or other neutral liquids to max. 70°C

AVK series 869 diaphragm actuated one-way altitude/flow control valves combine pressure altitude control with a flow limiter to maintain the level in a water tank or reservoir without the use of floats or sensors. The altitude pilot senses the pressure from the water level and opens to refill when the level drops below the setpoint, but keeps the flow within the adjustable maximum flow rate. The one-way mode makes sure to block the flow in case of reverse differential pressure.

Replaceable springs inside the pilots make it possible to operate in different pressure ranges and still keep the high precision. Setting and adjustment on control knobs on the pilots.

Variant 869/203H-001
Connection: Flanged
Material: Ductile iron
DN: DN65 - DN600
PN: PN10/16

Features

  • The lifted seat design controls the flow around the plug so that in case of cavitation this happens with minimal damage away from plug and seat
  • The parabolic shape of the plug creates a smooth regulating characteristic with low gain around the near-closed positions improving control performance at low flow
  • Non-symmetric axial position of rubber diaphragm results in low stretch stress when closed
  • Body and bonnet of ductile iron coated with fusion bonded epoxy, 300 micron, GSK approved, RAL 5017, according to DIN 3476 and WRAS-DVGW/W270/UBA
  • All rubber parts approved for drinking water
  • All non-coated internal parts in stainless steel or bronze
  • A needle valve fitted between the upstream side and the control chamber allows for adjustment of the regulation reaction time
  • Closing the needle valve isolates the control chamber and fixes the position of the main valve allowing for service of the pilot valve
  • Integrated lifting holes on body from DN150 for ease of handling
