NBR,EPDM,PTFE Diaphragm Control Valve, 1/2-14 IN, CL 200 LB

We are a leading control valve manufacturer in China, providing high-quality valves and control actuators designed to meet a wide range of industrial applications. Diaphragm valves play a vital role in shut-off and throttling services across various industries such as Chemical, Fossil Power Plants, Pharmaceutical, Mining, Nuclear Power Plants, and Water Treatment. These valves are designed to efficiently handle liquids, slurries, and vacuum/gases, featuring a flexible membrane—typically elastomer-reinforced with metal—that ensures a secure seal. Tensioned by a stem/compressor with linear movement, the membrane makes contact with the body seal, effectively isolating the operating parts from the flow. This design makes diaphragm valves ideal for handling viscous, hazardous, abrasive, and corrosive flows, preventing contamination. Available in sizes from 1/2 Inch to 14 Inch (DN15-DN350) with a CLASS 200 LB rating, they come in metals, solid plastics, rubber, and glass linings, catering to a wide range of chemical applications, including clear fluids and slurries. Their durability makes them suitable for low-pressure and slurry fluid environments, where other valves may corrode or clog.
