High performance safety valves with bellows to protect non-intrinsically safe solar plants with temperatures above 200 °C as well as district heating systems, boilers and pressure vessels. The metal bellows protects sliding and moving parts from the medium and thus from dangerous soiling. The spring housing and spring are protected against the ingress of steam and high temperatures.
