DONJOY sanitary stainless steel three piece butterfly valve, double flange butterfly valves
What is sanitary three piece butterfly valve?
Sanitary flange butterfly valve is composed by butterfly plate, valve body, seal ring, flange,flange seal and handle/actuator. Butterfly plate is connected with actuator and will start to work by the rotated actuator. When the valve is closed,the butterfly plate will form a seal with the sealing gasket, and the pipe system is cut off. When the valve body is opened,the pipe system is ready for transpotation.
