DIN/ANSI/GB/JIS/Bsw Diaphragm Valve with Flang Eg41j-10c

The structure of the diaphragm valve is different with general valve, is a new type of valve, is a special kind of block valves, its opening and closing is a diaphragm, made with soft materials within the valve body cavity with the valve cover cavity and drive components separated, is now widely used in various fields. The commonly used diaphragm valves are lined with a diaphragm valve, a fluoridated diaphragm valve, an unlined diaphragm valve, and a plastic diaphragm valve.
Diaphragm valves are fitted with a flexible diaphragm or composite diaphragm in the valve body and bonnet, and the closing part is a compression device connected to the diaphragm. The seat can be a weir or a pipe wall of a straight channel. The advantage of the diaphragm valve is that its control mechanism is separated from the dielectric pathway, which not only guarantees the purity of the working medium, but also prevents the possibility of working parts of the medium in the pipeline. In addition, the stem does not need to be sealed in any form unless used as a safety facility in the control of harmful media. Diaphragm valve, the work is only in contact with the medium diaphragm and the valve body, both can be used in a variety of different materials, so the valve can be ideal to control a variety of working medium, especially suitable for medium with chemical corrosive or suspended particles. Diaphragm valve working temperature is usually limited by the diaphragm and body lining material used, its working temperature range is about - 50 ~ 175 ºC. The diaphragm valve structure is simple and consists of body, diaphragm and valve head. The valve is easy to disassemble and repair quickly, and the diaphragm can be completed on site and in a short time.
