Our miniature safety valves in angle type offer reliable protection for the smallest pressure systems, pressure vessels and steam generators and boilers. With TÜV and European component approval, they meet the highest safety standards and are ideal for applications in sensitive pressure ranges. Thanks to optionally available clamping ring connections, the safety valves can be easily and quickly installed in small pipe dimensions, which considerably increases flexibility and efficiency in use. These safety valves are specially designed to ensure maximum safety and reliable protection against overpressure in limited spaces.
