Safety valves Danfoss are designed to protect components against excessive pressure. They meet rigorous quality requirements for industrial refrigeration installations set by international certifying organizations. The valves are suitable for working with HCFC, HFC, R717 (Ammonia), and R744 (CO2) refrigerants over a wide range of temperatures - up to 100°C. Safety valves are installed to prevent pressure from rising above the allowable level for individual system components and for the entire installation. In case of excessive pressure, the valves discharge refrigerant from the system. Danfoss safety valves provide the highest level of safety, high efficiency, and ease of installation.
