Steam-safety-valve

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.

Overpressure valves for steam generators and boilers

Steam applications are found widely in industry, but are also very feared. If steam comes into contact, for example, with water, a so-called steam shock occurs, which can have dangerous effects for people and machinery. Therefore, when selecting the components used, e.g. overpressure valves, particular attention should be given to high quality products. The valve serves to release unwanted overpressure, for example in a boiler. It must be ensured that the release of the steam and the hot water takes place in an environment free of people and components.  The steam overpressure can be released safely, for example, via a release pipe. The steam overpressure valves are securely fitted by the factory at your desired setting. Changing the setting manually at a later date is not advised. When the valve is released once, its functioning must be checked. Cleaning is also recommended. The valves in steam generators have to be checked according to TRD 601 every 4 weeks. If it is found that dirt has damaged the valve during its actuation, it should urgently be replaced. Otherwise, the seal of the entire system or another release in the event of overpressure cannot be guaranteed. Feel free to ask our technology department about the design and calculation of the pressure setting and the release performance. So that your steam system or boiler is reliably protected against overpressure, we exclusively use high quality materials. Every valve is also tested after it has been set.
