Series 451bG

Our stainless steel safety valves from the 451 series with stainless steel bellows set standards in terms of temperature resistance and features. These high-quality valves are specially designed to meet the highest requirements for corrosion and temperature resistance. They provide reliable protection for non-intrinsically safe solar systems and district heating supply systems that operate at temperatures above 200 °C.

The use of high-quality stainless steel and a stainless steel bellows in the construction of these safety valves guarantees exceptional durability and performance under extreme conditions. They are the ideal solution for demanding applications where reliability and safety at high temperatures are essential.
