AVK ONE WAY ALTITUDE LEVEL CONTROL VALVE, PN10/16
Reduced bore, AISI304/DI trim, AISI304 pilot, brass fittings/accs., EPDM/WRAS rubber, protected pos. ind.
Control valve, one way altitude level, for drinking water or other neutral liquids to max. 70°C
AVK series 879 diaphragm actuated one-way altitude control valves automatically maintain the water level in a tank or a reservoir without the use of floats or sensors. The altitude pilot senses the water level and opens to refill when the level drops below the set-point.
A replaceable spring in the pilot makes it possible to operate in different altitude ranges and still keep the high precision. Adjustment of the setpoint is by a control knob on the pilot.
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.

|---|---|
| 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, 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
- Feed back to the control is provided by the pressure from the height of the water column eliminating the need for floats or sensors
- Fittings, pipes and accessories in Ni-plated brass
