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.
