Diaphragm Valves

Diaphragm Valves are the valves which have body with one or more ports, an elastomeric diaphragm and a weir or saddle or a seat on which the diaphragm seats and closing the valve. There are two types of Diaphragm Valves, one type seals over a weir or saddle - Is called Weir type (Reduced bore type) and other seals over a full diameter bore seat.. is called Full bore type, Or Straight through type valve. The weir type valves are used in most common in process application and full bore type valves are used for slurry application to reduce blocking issue, but exists also as a process valves. Diaphragm valves can be manual hand wheel or pneumatic electric hydraulic actuated automated. Their application is generally as shut-off valves in process system and new designed is suited for regulating and controlling process flow. They are used for Industrial chemical plants, food and beverage, pharmaceutical and biotech industries. These valves were developed for Industrial applications, but later on the design was adapted for use in the bio-pharmaceutical industries by using compliant materials that can withstand sanitizing and sterilizing methods.
Features : Diaphragm valves are Dip proof Closure even with suspended solids in media. Universal use due to individual combinations of body and diaphragm materials adapted to media. Bonnet(hood) &Diaphragm pressure (compressor) piece are not in contact with the medium. Lift restriction as standard. Numerous actuation type of manual as well as automation are available. The diaphragm Valves offer the most corrosion protection possible at costs less than Hastelloy, Titanium, Zirconium and Tantalum. These valves are designed for highly-corrosive media, abrasion resistance, contamination & hot acids including hydrochloric acid, sulfuric acid, Sour gas(H2S), acetic acid & nitric acid. Aseptic Diaphragm Valves available which are the most important control components in Todayâs biopharmaceutical process s
