The structure of diaphragm valve is very different from that of general valves. It relies on soft rubber membrane or plastic membrane to control the movement of fluid. Commonly used diaphragm valve materials are divided into cast iron diaphragm valve, cast steel diaphragm valve, stainless steel diaphragm valve, and plastic diaphragm valve.
Commonly used diaphragm valves include rubber lined diaphragm valves, fluorine lined diaphragm valves, unlined diaphragm valves, and plastic diaphragm valves.
Product features of diaphragm valve:
(1) Low fluid resistance.
(2) Can be used for media containing hard suspended matter; since the media only contacts the valve body and diaphragm, no stuffing box is required, there is no stuffing box leakage problem, and there is no possibility of corrosion to the valve stem.
(3) Suitable for corrosive, viscous, and slurry media.
(4) Cannot be used in situations with high pressure.
