SFA Safety Relief Valves

The SFA Safety Relief Valves series is a family of angleway, direct-loaded safety relief valves designed to protect refrigeration vessels and other system components from excessive pressure. The series is built with low-temperature steel housings, stainless steel internal operating parts, and tightly closed spring housings that reduce the risk of refrigerant leakage. Across the range, the valves are available with multiple pressure-setting options and discharge capacities to match different refrigeration system requirements. The series is intended for use with several industrial refrigerants, including ammonia and carbon dioxide, and is designed so that the valve opens progressively as pressure rises and reseats after pressure drops below the closing range. Overall, the SFA series is intended for industrial refrigeration applications that require reliable overpressure protection with certified performance and refrigeration-specific construction.
