Aseptic Diaphragm valves
SED Flow control Hygienic Diaphragm valves are designed to suit aseptic processes in Biotech and Pharmaceutical industry. We offer Manual and pneumatically operated diaphragm valves manufactured with an intelligent design to ensure high quality and long lifetime.
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.
