Resilient seated, quarter turn, eccentric plug valve with welded nickel seat, for wastewater and other neutral liquids to max. 70°C
AVK eccentric plug valves are quarter turn with obstacle-free bore, adapted for pump control shut-off and throttling service with bi-directional flow in applications where waste water is contaminated with particles or hydrocarbon residues. The plug is fully vulcanized with AVK’s own hydrocarbon resistant NBR rubber compound which due to its sturdy design, double bonding vulcanization and the rubber’s ability to regain its original shape features an outstanding durability. The valve seat is corrosion resistant, welded nickel with a full port design that allows for high flow capability, an ISO 5211 actuator flange is incorporated in the valve housing and fusion bonded epoxy coating protects internally and externally.

- Bonnet bolts in stainless steel A4-70, encircled by the bonnet gasket and sealed with hot melt
- Fusion bonded epoxy coating to DIN 3476, GSK approved, blue RAL 5017
- V-type stem seal packing, easily adjustable during use
- Self-lubricating, stainless steel backed, PTFE coated, bronze bearing along with upper and lower bronze washers ensures consistently low operating torque
- Actuator mounting flange to ISO 5211
- Rectangular port opening, full port area
- Flange feet on large sizes for easy transport
- Seals from both directions up to 16 bar
- Plugs with integrated stems
- Plug stem extensions with zinc plating for corrosion protection
