Pneumatically Actuated Diaphragm Valve – Overview

The DIASTAR 025 has the highest closing forces in the portfolio of pneumatically actuated diaphragm valves. Functions include FC (fail-safe to close), FO (fail-safe to open) and DA (double-acting). Suitable wherever high pipe pressures of up to 10 bar need to be controlled on both sides. Pneumatic diaphragm valves are used for regulating, as well as closing, controlling and monitoring volume flows. This type of valve has decisive advantages when transporting contaminated, aggressive or abrasive media, due to its simple function and optimised construction. Only the valve body and diaphragm come into contact with the medium. Applications include contaminated, solid or ultrapure media.
