Diaphragm valves are widely used in various industrial applications due to their ability to control fluid flow effectively while providing reliable sealing. The rubber-lined diaphragm valve is designed to handle corrosive and abrasive fluids, featuring a flexible rubber diaphragm that creates a tight seal. For automated operations, pneumatic cylinder-operated diaphragm valves utilize compressed air to open and close the valve, offering quick and efficient control. The PTFE lined diaphragm valve is ideal for chemical applications, providing excellent resistance to corrosive substances, while FEP and PFA lined diaphragm valves offer enhanced chemical resistance and durability for harsh environments.



Various materials enhance the performance of diaphragm valves. The SG iron diaphragm valve provides strength and resilience, making it suitable for demanding applications. Ductile iron and cast iron diaphragm valves are common for heavy-duty operations, offering robust construction for various operating conditions. Epoxy-coated diaphragm valves are designed to resist corrosion and prolong service life. Connection types include screwed diaphragm valves and flanged ends diaphragm valves, providing flexibility in installation.



For automation, electric diaphragm valves and pneumatic diaphragm valve actuators enable remote operation and precise control over fluid flow. The PVC, UPVC, and PVDF diaphragm valves are lightweight and resistant to chemical attack, suitable for water treatment and other applications. Lastly, the Ductile Iron ASTM A536 Grade 60-40-18 diaphragm valve combines the benefits of ductile iron with high-strength properties, making it a reliable choice for various industrial processes.
