flange-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.

Safety valve with flange DN15 - DN100

Flange-safety-valves are often used in pipelines that are under pressure, in order to protect them from overpressure, especially in pipelines with higher nominal sizes and pressure ranges. The flange valves for pressure ranges from PN16 to PN40 are available in nominal sizes from DN15 to DN100. The set pressure can range from 0,2 bar to 40 bar, depending on the model. The flange of the safety valves is manufactured according to DIN EN 1092-1 or DIN EN 1092-2. The thickness tolerance is according to DIN 2533 or 2545, the sealing surfaces comply with DIN 2526 Form C. The seal for our flange-safety-valve can be either EPDM, metal or FPM. All flange-safety-valves are manufactured from grey cast iron EN-JL 1040, stainless steel 1.4408 or cast steel 1.0619+N. NieRuf GmbH is you well-known expert and currently offers three different models of flange-safety-valves: With closed lifting device and bonnet, with gastight cap and closed bonnet or with open lifting device and bonnet.

Insert of flange safety valves

Flange-safety-valves are favored in steam systems and steam boilers, since in these applications flange connections are predominant. The construction allows for significantly higher nominal sizes, which in turn allows for higher discharge capability compared to thread safety valves. This high discharge capability is especially relevant in large tanks, which makes the high quality flange safety valves from NieRuf the ideal valve.
