Leak-tight. Durable. Safe. When there is no room for compromise on leak-tightness, Swissfluid diaphragm valves combine reliable sealing with high media resistance and a simple, maintenance-friendly design.
The diaphragm forms a secure barrier between the process medium and the actuating mechanism. This protects the actuator components and reduces the risk of external leakage. Liquid and gaseous media can be reliably shut off, throttled, and regulated.
A variety of body, lining, and diaphragm materials allows for precise adaptation to the specific application. The integrated travel stop protects the diaphragm against mechanical overload and promotes a long service life.
A lined diaphragm valve completely isolates the process medium from the valve body and the actuator by means of a flexible diaphragm. As a result, only the resistant lining and diaphragm materials come into contact with the medium. This design ensures a high level of tightness and is particularly suitable for demanding applications involving corrosive or aggressive process media.
Swissfluid diaphragm valves are used for demanding process media, for example in the chemical, pharmaceutical, petrochemical, and paper industries, as well as other process sectors. They are particularly suitable for corrosive, abrasive, and contaminated media, as well as for applications requiring reliable shut-off and a high level of tightness.
Various housing materials and linings are available depending on the application. These include, for example, cast steel or cast stainless steel with PFA or PFA-AS linings, which meet the relevant resistance requirements. Depending on the application, various materials such as PTFE or PTFE-AS are used for the diaphragms; the choice depends on the medium, temperature, and operating conditions. Support diaphragms are available in EPDM and FPM versions.
Yes. Swissfluid diaphragm valves can be automated using various actuators. This allows them to be integrated into modern process plants, enabling reliable remote control as well as safe automation of shut-off and control processes.
