Swing-check-valves with intermediate flange that matches your requirements

Do you have special requirements for your intermediate flange non-return valve? A one of a kind application, where a standard swing-check-valve simply can not be used? We would love to help you find an individual solution for your application. Whether it is aggressive media like DI water, high pressure ranges or high temperatures – our experts will help you find the right product or manufacture one specifically for your application.


Do you need a standard intermediate flange non-return valve for your pipeline, preferably at low cost? You are based in the USA and need flange sizes ANSI150? No problem for us – simply order your intermediate flange non-return valve at low cost from our online shop, or give us a call. Nominal sizes ranging from DN32 to DN400 and pressure ranges from PN10-PN40 fulfill all requirements in nearly any application. They are made of stainless steel, steel, PVC-U, PP, PVDF or aluminum bronze. Seals can be NBR, FKM, Viton, RPDM, PTFE or metal. For US customers, intermediate flange non-return valves can be made in ANSI 150. Also, the valves can be manufactured with a spring reset or without spring.
