Swing-check-valve intermediate flange type

Intermediate flange swing-check-valves are crucial in closed systems, power plant construction, pipeline construction as well as biogas and gas power plants. They are protective devices to prevent backflow, which is an important safety precaution. When implementing an intermediate flange non-return valve, quality is especially important in order to guarantee safety and longevity.
Intermediate flange swing-check-valves are also often used in shipping industry, oil production and processing and water treatment plants. Intermediate flange swing-check valves from NieRuf are characterized by a very short thus space-saving construction. They are self-centering and the eyebolt makes them easy to implement and exchange.

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 or ANSI300? 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 DN500 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 and ANSI 300. Also, the valves can be manufactured with a spring reset or without spring.
