Sanitary diaphragm valve

Welding diaphragm valve is a special form of truncated valve. The opening and closing parts are a piece of soft material made of diaphragm. It will be the body cavity and the valve cover cavity separated. Welding diaphragm valve due to the valve body lining process and diaphragm manufacturing process, the larger valve body lining and larger diaphragm manufacturing process are difficult. So the diaphragm valve should not be used for larger diameter, generally used in ≤DN200 pipeline.

Welding diaphragm valve applicable to what occasions:

Diaphragm valve welding due to the diaphragm material.Diaphragm valve is suitable for low pressure and temperature is not high occasions. Generally do not exceed 180℃. Because diaphragm valve has good anti-corrosion performance. It is generally used in corrosive media devices and pipelines. Because the diaphragm valve temperature applicable medium is limited by the lining material and diaphragm material of the diaphragm valve body.
