Metal seat gate valve for drinking water and neutral liquids to max. 70°C

AVK metal seated wedge gate valves are primarily designed for the flow isolation of a length of pipeline or piece of equipment. It uses a ductile iron gate that houses bronze rings to ensure a watertight seal. The non-rising stem design ensures the stem thread is adequately lubricated by the water passing through the valve. In essence, the whole internals are water dependent for lubrication, a factor that safeguards the longevity of the valve.
