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.

Y Type Diaphragm Valve
The KOSEN Y Type Diaphragm Valves includes the valve body, the valve stem, the isolation ring, the diaphragm and the diaphragm cavity cover. 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
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
Stainless Steel Thread Weir Diaphragm Valve
The KOSEN Stainless Steel Thread Weir Diaphragm Valves is specially designed to control the general corrosive medium, and can be used for opening and closing and throttling of various pipelines or equipment. The lining valve is suitable for urban construction, chemical industry, metallurgy, petroleum, pharmaceuticals, food, beverages, and environmental protection.Learn More
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
