The water valves give modulating regulation of the condensing pressure and so maintain it constant during operation. When the refrigeration plant is stopped, the cooling water flow is shut off automatically.

Pressure and temperature controlled water valves are used for regulating the flow of water in refrigeration plants with water-cooled condensers.

Pressure controlled WVFX can be supplied in stainless steel housing which can be used in connection with sea water cooling of condensers and compressors.

Temperature controlled water valves opens on rising sensor temperature.
