The KOSEN 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.

The diaphragm is provided with a through hole on the top of the diaphragm, which is arranged in contact with the stem and can move along with the stem and extend the hole to the outside. The outer sleeve of the indicating rod is provided with a shaft sleeve, and the shaft sleeve is fixed on the inner wall of the through hole.Learn More
Straight Through Diaphragm Valve
The KOSEN Straight Through 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 liquid pipeline. Diaphragm valve is a special type of truncation valve, flexible seal open and closed, to ensure no leakage, streamlined flow channel, so that the pressure loss is small, no packing letter, so there is no leakage, the valve body and cover are separated by the middle diaphragm, so that the valve cover above the diaphragm, the valve stem and other zero parts are not eroded by the medium and the diaphragm can be replaced, The maintenance cost is low, the lining material is diverse, it can be applied to all kinds of media, and has the characteristics of high strength and good corrosion resistance.Learn More
