Pneumatic Diaphragm Valve price As a part of the valve body, the diversion weir of the pneumatic weir diaphragm valve is equivalent to the valve seat, and the diaphragm is pressed on it to intercept the flow of the medium. Diaphragm valves of this type are generally larger in size. The convex diversion weir reduces the stroke of the diaphragm valve from fully open to fully closed, thereby reducing the stress and strain of the diaphragm. When it is closed, the valve disc with the diaphragm moves down to make it seal with the weir of the valve body to meet the requirement of cutting off the fluid.

Diversity of valve body materials, including cast iron, nodular cast iron, cast steel, forged steel and lining various materials. 2. Lining materials include: Glass ETFE PFA PVDF Halar rubber, which can also be specially processed according to requirements. 3. The unique patented design of the bonnet prevents the diaphragm from being over-tightened and over-pressured, so that the diaphragm is in a normal working state. 4. It can be maintained online, reducing maintenance costs and man-hours, and providing you with more convenience. 5. The valve cover is completely separated from the fluid, which avoids fluid corrosion and makes the valve safer and more reliable. 6. No bottom shaft leakage, avoiding the bottom shaft leakage of conventional valves. 7. The sealing of the diaphragm can ensure zero leakage of the valve. 8. Different fluorine lining materials and coating materials can meet your needs for different media. 9. Diaphragm valve is also suitable for use in vacuum conditions. Why Choose Us? 1.
