The Johnson Controls V47AB-5C TEMP ACT MODULATING Valve; TEMP Water REG Valve; 1/2″75/135F CROSS AMBIENT
The V47 modulating valves regulate the flow of water to maintain a desired temperature. V47A valves OPEN on a temperature increase at the bulb while V47N valves CLOSE on a temperature increase at the bulb. The V47 temperature valves are widely used on heat exchangers to maintain optimum operating temperatures of internal combustion engines, air compressors, hydraulic oil, etc. Important benefits from the use of water valves include maximum operating efficiency of the equipment and a substantial savings effected by the conservation of water flow. They are used on condenser applications where expensive fluids are economically recovered or where the use of cooling water is restricted and on such varied applications as the temperature control of swimming pools and the control of paint temperatures on industrial printing machines.
