Series 851bG

Our high-performance safety valves with bellows offer an optimum solution for protecting solar systems that are not considered intrinsically safe and where temperatures of over 200 °C can occur. They are also ideal for use in district heating systems, steam boilers and pressure vessels. These valves are characterized by their metal bellows, which effectively protect sliding and moving parts from direct contact with the medium and thus prevent the formation of dangerous deposits.

In addition, our safety valves offer reliable protection for the spring chamber and the compression spring against penetrating steam and high temperatures. These features guarantee a high level of operational safety and durability of the valve, even under extreme conditions.
