Waukesha Cherry Burrel Diversion Valve
Flow Diversion Valve: It is a valve to divert flow in the fluid line. It works on the signal coming from the temperature sensor/Transducer to divert the flow of the fluid. The Waukesha Cherry-Burrell Flow diversion valve is excellent in operational use in the factory. The dairy firms uses this kind of valve to divert the flow of the fluid before the pasteurizer line. The Pasteurizer need above 90 degree Celsius temperature, if the temperature of the fluid is less than 90 degree then the temperature transducer gives signal to the diversion valve and then the diversion valve divert the fluid to the Balance Tank. In the other hand if the temperature is above 90 degree Celsius then the diversion valve is operates to the forward direction .
