ON/OFF FLOAT LEVEL CONTROL VALVE, PN10/16

Full bore, AISI304/DI trim, AISI304 pilot, brass fittings/accs., EPDM/WRAS rubber, protected pos. ind.

Control valve, ON/OFF float level, for drinking water or other neutral liquids to max. 70°C

AVK series 879 diaphragm actuated level control valves automatically control the water level in a tank or a reservoir by means of a float.

The float activates the pilot that controls the main valve to keep the level around the predetermined setpoint. Control mode is ON/OFF.

Both full bore and reduced bore versions are available with the full bore having full capacity and the reduced bore having increased precision and smooth regulation at low flow rates.

Variant 879/106X99-001
Connection: Flanged
Material: Ductile iron
DN: DN50 - 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, 300µm, GSK approved, RAL 5017, according to DIN 3476 and WRAS-DVGW/W270/UBA
  • All rubber parts approved for drinking water
  • All non-coated internals made of stainless steel or bronze
  • Seat and pilot in stainless steel AISI 304
  • 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
  • Fittings, pipes and accessories in Ni-plated brass
