Whatever the application, Edwards has the right solution to meet your process requirements. Well known for its innovation in pump design, Edwards applies the same energy and commitment to its valves. The result is an extensive range of valves, with a choice of actuation methods, materials and size. Materials of construction have been uncompromisingly selected for performance in high vacuum. Confidence in Edwards valves begins early in the design process. We use techniques such as finite element analysis to optimise the design of the valve. An arduous testing program in EDWARDS environmental testing laboratory prior to release to production ensures that every valve we supply will meet the needs of your application. Once in production, all valves are subject to stringent quality control and are individually tested with a helium mass spectrometer leak detector. Bellows sealed pipeline valves are manufactured with 100% grease free O-rings exposed to vacuum delivering unrivalled low contamination levels.
