Three Way Diaphragm Valve
The GAIRUI Three Way Diaphragm Valves is used to control non corrosive or general corrosive medium. The inner cavity surface of the valve body is unlined or covered with various kinds of rubber, suitable for different working temperature and fluid pipeline. The variety of lining materials can be applied to all kinds of media and has good corrosion resistance. The valve body and the cover are separated by the middle diaphragm, so that the valve cover and the valve stem part of the diaphragm are not eroded by the medium, and the diaphragm valve is a special stop valve.
