Metal seat gate valves with rotating, non-rising stem. Operating direction clockwise to close or clockwise to open. For drinking water and neutral liquids to max. 70°C, and sewage without solid impurities. On DN350-600 operation is either by manual handwheel/gearbox or by electric actuation; on DN≥700 operation is possible only via gearbox or actuator that is able to support the axial thrust loads.

AVK metal seated gate valves are designed for isolation of pipeline sections or individual pieces of equipment. The use of a ductile iron body and gate with bronze seal rings creates a heavy duty, watertight seal. The non-rising stem design ensures the stem thread is adequately lubricated by the water passing through the valve, a factor that safeguards the longevity of the valve.
Variant 54/4344-002
Connection: Flanged
Material: Ductile iron
DN: DN350 - DN1000
