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.

Electric Actuator Diaphragm Valve
The KOSEN Electric Actuator Diaphragm Valves is composed of a valve body, a valve cover, a valve stem, a disc, a diaphragm, an electric device and other driving parts.The opening and closing of the valve is driven by the connecting shaft of the electric device to drive the stem nut, so that when the valve rod moves axially, the valve flap can be driven up and down to achieve. When the power supply breaks down and the valve is in urgent need of opening and closing, the hand - electric handoff handle should be first converted to the manual marked position, and the flash door can be opened and closed through the rotating handwheel. When rotating clockwise, the valve can be turned off; otherwise, it will turn on. When the electric operation is resumed, the switch handle must be switched to the position marked with electric mark, so that the electric operation can be carried out.Learn More
Cast Steel Weir Type Diaphragm Valve
The KOSEN Cast Steel Weir Type Diaphragm Valves has self draining function to ensure no residue and make the pipeline cleaner and healthier. The valve body has various materials, such as cast iron, ductile iron, cast steel, forged steel and lining. Lining materials include: Glass, ETFE, PFA, PVDF, Halar rubber, which can be specially processed according to needs. The unique valve cover patent design prevents the diaphragm from being too tight and the pressure is too high, so that the diaphragm is in normal working condition. The seal of the diaphragm can be zero leakage of the valveLearn 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
