Diaphragm valves also known as exist of a value body with two or more gate, a diaphragm, & a “weir or saddle” or seat upon which the diaphragm closes the valve. The valve is put out from either plastic or metal.
Diaphragm valves can be controlled by various types of actuators e.g. manual, pneumatic, hydraulic, electric etc…
Primitively, the diaphragm valve was making for use in industrial applications. Consequent the design was adapted for use in the bio-pharmaceutical industry by using compliant materials that can put up with purify & sterilizing methods.
There are two most important categories of diaphragm valves: weir or saddle & other seals over a seat. Some times it’s called a “full bore or straight-way” valve. Saddle diaphragm valves are the most usually in process applications & the seat is more used in slurry applications to recede blocking issues but as a process valve too.
Diaphragm valves commonly come in two-gate forms; they can come with three ports too. Its call T-Valves. & more called block-valves.
