AVK ON/OFF FLOAT LEVEL CONTROL VALVE, PN10/16
Reduced 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 879/006X99-001 | |
|---|---|
| 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, 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
