775 Series

The Rockwood Swendeman 775 Series RSL-SS safety relief valves are designed for air and gas service in cryogenic and industrial systems where PED compliance is required but ASME certification is not. Featuring a stainless steel body, these non-ASME coded valves deliver reliable overpressure protection with excellent corrosion resistance and clean performance in demanding environments.

Engineered for use on cryogenic storage tanks, pipelines, and pressurized gas systems, the 775 Series RSL-SS provides consistent relief control and rapid resealing for high-purity or high-value gases such as oxygen, nitrogen, argon, and hydrogen. Its rugged stainless steel construction ensures long-term durability and system integrity, even under extreme conditions.

Backed by the trusted Rockwood Swendeman name, the RSL-SS offers a dependable, code-conscious solution for air and gas safety relief in both cryogenic and industrial applications.
