WVB 3-Way Valves

3-way valves with lifting stem. Stem sealing provided by metal bellows for hermetic sealing.

AWP 3-way valves are designed to be used in the refrigerant cycles of industrial refrigeration systems. They are normally installed between pressure vessels or between pressure pipes and two safety valves. AWP 3-way valves are activated by a handwheel. Turning the handwheel clockwise opens the outlet nozzle facing away from the handwheel. Thus the other outlet nozzle closes forcibly. It is therefore not possible to lock both outlets at the same time. In WVB 3-way valves the stem sealing is provided by a metal bellows which ensures a complete hermetic sealing. AWP 3-way valves are maintenance-free.
