stainless-steel-safety-valve with flange or thread connection

The stainless-steel-safety-valve is a kind of safety valve, that is characterized by its resistance to a wide variety of media. This means a stainless-steel-safety-valve with FKM seal can be used with oily air, in extreme temperatures, and with chlorinated water, VE water and drinking water, depending on the alloy and quality of the stainless steel. Our safety valves are made of high quality V4A stainless steel such as 1.4408 and 1.4571. These materials are especially resistant to acids. That's why our safety valves are often used in pharmaceutical industry, medical technology, with drinking water and wherever aggressive media come into play. The high resistance to aggressive media makes stainless-steel-safety-valves ideal for chemical and petrochemical industry. But even in food industry, stainless-steel-safety-valves come in handy, due to their resistance to disinfectants and cleaning agents.

Different models of stainless-steel-safety-valves

The big advantages of stainless-steel-safety-valves from NieRuf GmbH are not only the high quality workmanship and the available acceptances (material certificate 3.1 or TÜV individual acceptance 3.2 on the preset pressure), but also the wide range of models, nominal sizes (¼“ - DN100), preset pressures (0,2 bar to 350 bar) and connections (internal & external thread, flange, clamp etc.). Please feel free to explore our range of stainless-steel-safety-valves down below, or use our configurator to assemble your ideal valve.
