Diaphragm valves

What is a Diaphragm valve?

A Diaphragm valve is a flexible, pressure responsive element that transmits force to throttle, open or close a valve. Diaphragm valves separate the flow stream from the closure element using an elastomeric diaphragm, which is a flexible, durable material.

The diaphragm in a valve serves as a seal to prevent the liquid encountering other operating parts of the valve, avoiding contamination, corrosion and wear. The diaphragm valve is well suited for the control of the flow of corrosive materials and avoiding contamination of product within many processes around “clean utilities”, WFI (water-for-injection), and many purified water applications in Pharma & Biotech industry.

Flexachem Manufacturing Ltd offer SED Flow Control Gmbh valves. All are manufactured in Germany to the highest ASME BPE Standards.

The range of SED diaphragm valves supplied by Flexachem can be operated by a handwheel or a pneumatic actuator. The video below shows how the SED KMA 905 handwheel operated Diaphragm valve is operated.
