NieRuf: your experienced safety valve partner!

Safety valves are essential in pipeline construction as well as in other closed construction systems such as biogas plants and industrial facilities. They are not only mandatory by law, but also lifesaving safety devices. They are used to prevent overpressure that can result in environmentally harmful gases and fluids. If you want to make sure that your facility is protected against overpressure, you will need to work with safety valves. NieRuf is an expert in that market segment and therefore a competent specialist for those who wish to install safety valves. No matter which nominal size, seal variety or connection variety you need to install, we will have the matching product in stock. Please do not hesitate to talk to us. We would love to advise you on our valve models.
