Fast reacting nozzle check valve with spring return, for drinking water and other neutral liquids to 80°C
The AVK spring loaded nozzle check valve is a reliable, fast reacting blocker of reverse flow in water pipes. In case of pump stop the spring loaded valve cone will make sure the water flow is shut off swiftly and quietly before it can change direction and cause water hammer. All metal parts are made of either stainless steel or epoxy coated ductile iron.
