Thermostatic operated water valve type WVTSis suitable for controlling the temperature of aflow of water or neutral brine.WVTS opens on rising sensor temperature andis indirect servo operated thermostatic valve.It is suitable for controlling temperature inindustrial applications by regulating thequantity of cooling water or neutral brine thatcools down the process.The valves are self-acting, i.e. they operatewithout the supply of auxiliary energy such aselectricity or compressed air.The required temperature is maintainedconstant without unnecessary use of coolingwater in cooling systems.The operating economy and-efficiency aremaximized.
