Diaphragm Valves Manufacturers

Diaphragm Valves use a rubber, plastic or elastomer diaphragm to seal the stem. Diaphragm valves are generally more suitable for process liquids because of the low-pressure drop and the virtual impossibility of leakage. Diaphragm valves are controlled by a hand wheel. These valves are slower to operate and damaged by over tightening. Diaphragm valves are packless with solid Teflon diaphragm. Diaphragm valves are glandless valves that use a flexible elastometric diaphragm as the closing member and affect an external seal.
