Description
Henry ammonia pressure relief valves are designed to provide dependable overpressure protection in industrial refrigeration systems using ammonia refrigerant. Built with a robust forged steel body, these valves are engineered to handle the demanding conditions common in ammonia applications. All pressure-retaining components are constructed from steel, with internal parts made from plated or stainless steel for durability and corrosion resistance. A chemically inert, non-stick PTFE seal ensures reliable performance and long service life. Female NPTF threaded connections help ensure leak-resistant installation, while the angled valve design allows flexibility when routing discharge piping. Suitable for ammonia as well as HFC, HCFC, HFO, and CO₂ refrigerants, Henry pressure relief valves are available in multiple set pressures and sizes to meet a wide range of system requirements. Each valve includes an installation date sticker and provisions for third-party identification tags, making them a reliable and compliant choice for protecting compressors, vessels, and other refrigeration system components.
