Diaphragm valve

The structure of the diaphragm valve is very different from that of ordinary valves. It is a new type of valve and a special type of block valve. Its opening and closing parts are a diaphragm made of soft materials, which separates the inner cavity of the valve body from the inner cavity of the valve cover and the driving parts. Now it is widely used in various fields. Features: (1) Small fluid resistance. (2) It can be used for media containing hard suspended solids; As the medium only contacts the valve body and diaphragm, there is no need for stuffing box, no stuffing box leakage problem, and no possibility of corrosion to the valve stem. (3) Suitable for corrosive, viscous and slurry media. (4) It should not be used in high pressure situations.
