Series 851bHF

Our D/G/H and F approved safety valves made of corrosion-resistant gunmetal, equipped with a metallic bellows and a metal-to-metal sealing, have been specially developed for use in heating and cooling systems within industry and building technology. These valves offer an optimum solution, particularly for systems that use indirect heating or cooling by means of heat exchangers, and are characterised by their universal applicability.

In accordance with the high standards of the Swiss SWKI, our safety valves not only guarantee reliable performance, but also compliance with relevant safety requirements. Their corrosion-resistant gunmetal construction ensures long-lasting functionality and safety in your systems.
