compact relief valve

For more than 50 years, HOERBIGER has been successful with relief valves for compressor safety technology. They offer protection against oil mist and gas explosions, both to people and equipment. The HOERBIGER EVN relief valves are ATEX-certified and meet the API 618 standard. Due to low-mass valve plates and low response pressure, they react instantly in the event of an explosion. Thanks to the integrated flame arrester, they ensure flameless pressure relief. Following an explosion, they immediately close again and are sealed, lowering the risk of secondary explosions. HOERBIGER relief valves allow continuous operating of the compressor immediately after an explosion. They are maintenance-free and operational for many years.
