cryo 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.

Cryo-safety valve for cryogenic liquids and gases

Special cryo-safety valves serve to protect people and machinery in a low-temperature system, liquid nitrogen system or medical technology, for example for the use of liquid nitrogen or cryogenic oxygen. A system that works with cryogenic media, for example liquid nitrogen or cryogenic oxygen, always has two safety valves that are installed in parallel. These are controlled via a specially tested cryo-ball valve. This is necessary if a cryo-valve does not work or has to be serviced because of the cryogenic operating conditions. A cryo-safety valve must always be ready for use because a low-temperature system cannot simply be switched off. Our cryo-safety valves are made from high quality stainless steel and have a PTFE seal The are available in nominal widths ¼“ – 1“ inches. The setting range extends from 0.2 bar to a maximum of 70 bar. The valves are suitable for temperatures up to minus 200 degrees Celsius. We are happy to help you when designing your valve, get in touch.
