For the highest demands and requirements completely made of highly corrosion- and temperature-resistant stainless steel for the protection of non-intrinsically safe solar systems with temperatures above 200 °C, district heating supply systems and steam systems. The stainless steel bellows also protects sliding and moving components as well as the spring chamber from medium deposits and high temperatures. Due to the approval for both liquid and gaseous media, the safety valve offers a high level of functional safety, regardless of the phase condition of the medium.
