High quality swing check valves or dual plate check valves for your specific needs!
Challenging applications ask for a variety of different check valves. Depending on the mounting position, installation place, temperature and medium, different check valves should be used. Depending on the medium, which flows through the system, the temperature and the installation place, the material of the swing check valves needs to be chosen. NieRuf offers check valves made of stainless steel, steel, PVC-U, PP; cast iron and GGG40. They come with FPDM, PTFF, NBR and FKM seals, in diameter DN15, DN20 and even up to DN500 or DN600.
Your request regarding check valves is our motivtion! NieRuf!
No matter what your challenge regarding check valves looks like, our team at NieRuf Industriearmaturen will take it on! Together with you, we will find the right solution. With demanding or aggressive media, we suggest check valves made of stainless steel. Frequently used backflow preventers are check valves and dual plate check valves. The swing check valves can be set up with an additional spring to facilitate closing. With high pressure ranges and high flow rates (which means high KV/KVS), dual plate check valves should be used, for they have a significantly low loss of flow. If you need specific connections to you pipeline, the DISCO- check valve can be used. We would love to help you find the right swing check valve from our extensive product range.
