Diaphragm valves play a crucial role in shut-off and throttling services across diverse industries, including Chemical, Fossil Power Plants, Pharmaceutical, Mining, Nuclear Power Plants, and Water treatments. Capable of efficiently handling liquids, slurries, and vacuum/gas, these valves feature a flexible membrane, typically elastomer reinforced with metal, ensuring a secure seal. Tensioned by a stem/compressor with linear movement, the membrane contacts the body seal, effectively isolating the operating parts from the flow. This design renders diaphragm valves ideal for viscous, hazardous, abrasive, and corrosive flows, preventing contamination. Available in sizes ranging 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.
