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.
