Concentric butterfly valve with loose liner for drinking water and neutral liquids. AVKs Series 76 range of concentric butterfly valves are available in wafer and lug design with lever and gearbox. They provide best in class to our customers for concentric loose liner butterfly valves and are produced at excellent quality using AVK GUMMI rubber liner and fusion bonded epoxy coating on ductile iron. The design is with anti-blowout shaft, hexagon connection, low friction bearings and an EPDM liner with reinforced seating area and profiled flange gaskets.

ductile iron


The flange gasket is thick and profiled to ensure correct fit in valve body, and the high quality EPDM ensures continuous elasticity and no brittleness even towards end of lifetime (alternative NBR, or high temperature EPL)

Rubber is approved for drinking water (minimum biofilm and minimum contamination ensured)

Integrated profiled gasket from AVK GUMMI

High quality fusion bonded epoxy coating on ductile iron for higher strength (alternative SS AISI 316 disc)

Ergonomic handle DN50-200 and wormgearbox for larger sizes

Long neck design for insulation AISI 420 stainless steel shaft

Double PPOM bearing and an EPDM 0-ring as backup sealing safely ensures no leakage from the neck

Reinforced seating area at shaft to ensure less deformation on installation, Shaft holes dimensioned to create compression around the shaft

Pin-less and two stub shaft design ensures a higher flow compared to a though-pin

PTFE coated bearings at the top and bottom of the disc for low friction also during the end of lifetime C especially important for motorized butterfly valves


Electric actuator SS AISI 316 disc High temp EPDM liner (EPL) Lug type and wafer types
