Diaphragm Valve

Diaphragm valves are engineered for tough work environments in the chemical processing, water treatment, pollution control, food and beverage, mining, pharmaceutical, pulp and paper, power generation industries. Diaphragm valves are available in two basic forms: weir type and straight through types. The weir design is best for general use applications or for tough corrosive and abrasive services. The straight through type can be used in situations where the flow direction changes within the system.

Types of Diphragm Valve

Primarily there are three basic designs of diaphragm valves
