Safety valves made of stainless steel, angle-type with threaded connections or cutting ring threaded connections

These angle-type safety valves are available for the first time with TÜV and European component approval. This allows the use of tested and approved quality on the smallest pressure tanks and small steam boilers with neutral and non-neutral gas and liquid mediums. The cutting ring threaded connections available as an option make this valve quick and easy to install for use in small pipelines.
