Loose liner butterfly valve for neutral liquids like drinking water, river water and treated wastewater free from solids and fibrous impurities to max 70°C

The AVK Series 76 is a wide range of concentric, loose liner butterfly valves available in both flanged, wafer and lug design and with AVK's own high quality rubber liner that significantly increases the service life. The one-piece replaceable liner also serves as a profiled flange gasket and comes in either drinking water approved EPDM, high temperature EPDM or hydrocarbon resistant NBR. Disc material is stainless steel or epoxy coated ductile iron. The shaft in stainless steel, installed in low friction bronze/PTFE bearings in an anti-blow out design plus the unique disc sealing profile results in low operating torque and long life.
