Type AVTB temperature controllers are self-acting and used to control the water temperature in hot water tanks, heat exchangers, oil preheaters etc. Controller closes on rising temperature.
Type WVTS is a cooling water regulating valve that is suitable for controlling the temperature of a flow of water or neutral brine and opens on rising sensor temperature. Large self-acting cooling water regulating valves for accurate flow control based on sensor temperature Open on rising temperature Cast iron valve body Thermostatic pilot elements (2 or 5 m capillary tube) ordered separately
Type WVS water valves are used for regulating the flow of water in refrigeration plants with water-cooled condensers. The water valves give modulating regulation of the condensing pressure within defined limits during operation. When the refrigeration plant is stopped, the cooling water flow is shut off automatically. Water valves can be used with flammable refrigerants. Double sealing between the refrigerant and the water line ensures that in case the bellows damage and the refrigerant leak, it cannot enter in to the water. This severely limits the safety implications. It means that the valve can be used together with a double walled heat exchanger and water circuit in such a system does not need to be considered as part of the installation for flammable refrigerants.
