Diaphragm Valves for Hermetic Media Separation and Safe Process Control

Control demanding media with absolute safety. With our flow-optimised weir-type diaphragm valves, only the diaphragms and valve body come into contact with the process medium. This hermetic separation between the actuator and the valve body reliably protects your processes. The valves are suitable for both high-purity hygienic applications and for abrasive or heavily contaminated media.

Technical Specifications & Design Features

Choose flexibly between durable grey cast iron (GG-25 / EN-GJL-250) and high-quality stainless steel.

Adapt the diaphragm precisely to your process. Proven EPDM or highly resistant PTFE/EPDM are available.

Integrate the valves directly into your plant. Use internal threads, weld-on ends (EN 10357-A) or DIN flanges.

Design flexibly with a wide range of sizes. We offer threaded connections from 1/2" to 2" as well as flanged versions from DN15 to DN150.
