Sanitary Diaphragm Valve – sanitary-stainless-steel valves and fittings manufacturer

The working temperature of the pneumatic sanitary diaphragm valve is usually limited by the materials used in the diaphragm and the valve body lining. Its working temperature range is about -50～175℃. The imported diaphragm valve has a simple structure, consisting of three main parts: valve body, diaphragm and bonnet assembly. The valve is easy to quickly disassemble and repair, and the replacement of the diaphragm can be completed on site and in a short time.
Pneumatic sanitary diaphragm valve is a special form of shut-off valve. The difference from other valves is that it adopts a structure without a stuffing box; the rubber diaphragm can completely isolate the corrosive medium in the flow channel from all driving parts. So as to eliminate the disadvantages of “running, leaking, dripping and leaking” of the usual valves.
Replace the valve core assembly with a corrosion-resistant lining and a corrosion-resistant diaphragm. The pneumatic sanitary diaphragm valve body is made of cast iron, cast steel, or cast stainless steel, and is lined with various corrosion-resistant or wear-resistant materials, diaphragm rubber and polytetrafluoroethylene. The liner has strong corrosion resistance and is suitable for the adjustment of strong corrosive media such as strong acid and strong alkali.

The structure of the sanitary diaphragm valve is quite different from the general valve. It is a new type of valve and a special form of cut-off valve. Its opening and closing part is a diaphragm made of soft material, It is separated from the inner cavity of the valve cover and the driving parts, and is now widely used in various fields.

The sanitary diaphragm valve is equipped with a flexible diaphragm or combined diaphragm in the valve body and the valve cover, and the closing part is a compression device connected with the diaphragm.

The valve seat can be a weir shape or a pipe wall that directly leads to the flow channel. The advantage of the diaphragm valve is that its operating mechanism is separated from the medium passage, which not only ensures the purity of the working medium, but also prevents the possibility of the medium in the pipeline from impacting the working parts of the operating mechanism.
