The range of Danfoss WVS automatic water valves are used to regulate the flow of water in refrigeration plant with water-cooled condensers (HCFC, HFC and HC) in order to ensure constant proportional regulation of condensing pressure. The water valve modulates the water flow to maintain the condensing pressure at a constant level during operation. When the refrigeration plant is stopped, the cooling water flow is shut off automatically.

Below 20% of the maximum capacity, the WVS valve operates as an on-off regulator (full open/full closed).
