Air Operated Diaphragm Valves

Originally, the diaphragm-operated valve was manufactured for industrial applications. However, over the years; the design of the pneumatic-operated diaphragm valve was adapted for use in the biopharmaceutical industry by using compliant materials that can withstand sanitising and sterilising methods. Air-actuated diaphragm valves can be manual or automated. As a shut-off valve, they are commonly used in process systems within the Industrial, Food and Beverage, Pharmaceutical and Biotechnology industries.

The two main categories of air-operated diaphragm valves include seals over a saddle or weir and those known as the full bore or straight-way valve, where the seal is over a seat. The weir or saddle type diaphragm operated valve is most commonly used in process applications, while the seat type is common in slurry applications and exists as a process valve. While a pneumatic-operated diaphragm valve will usually come as a 2/2-way diaphragm valve, they are also available with three ports (3/2-way diaphragm-operated valves).
