Product Description

Superior offers the most complete range of refrigeration relief valves in the industry. All valves have been designed, constructed and rated in accordance with ANSI/ASHRAE 15-1994 Standard Safety Code for Mechanical Refrigeration.

Each valve is stamped U.V./N.B. to indicate National Board certifications as to capacities. Certified National Board ratings are printed on the next page.

These pressure-relief valves are all PTFE seated, permitting their use in applications of either high or low temperatures where the conventional rubber seated valves are often completely unsatisfactory.

Part Numbers indicate style and size of relief valve only – customer must specify pressure setting when ordering.
