We are a premier control valve manufacturer in China, delivering high-quality valves and control actuators designed to meet the diverse needs of various industries.Diaphragm valves are essential for shut-off and throttling services across various industries, including Chemical, Fossil Power Plants, Pharmaceutical, Mining, Nuclear Power Plants, and Water Treatment. These valves are highly effective at handling liquids, slurries, and vacuum/gas, with a flexible membrane—typically elastomer reinforced with metal—ensuring a reliable seal. Tensioned by a stem or compressor with linear movement, the membrane presses against the body seal, isolating the operating components from the flow. This design makes diaphragm valves ideal for handling viscous, hazardous, abrasive, and corrosive fluids, preventing contamination.

Available in sizes from 1/2 inch to 14 inches (DN15-DN350) with a CLASS 200 LB rating, they are constructed from materials such as metals, solid plastics, rubber, and glass linings. This versatility makes them suitable for a wide range of chemical applications, including clear fluids and slurries. Their design also extends their service life in low-pressure and slurry fluid environments where other valves may corrode or become clogged.For more，know more about China Manufacturers.
