Application Overview
Industrial HVAC systems — including centrifugal and screw chillers, cooling towers, and large air-handling units — require pressure safety and service valves that meet ASME codes and satisfy insurance underwriters. Cyrus Shank provides UV-stamped relief valves with full individual test documentation for mechanical engineers of record and facility compliance teams.
Common Challenges
- !State mechanical codes and insurance carriers require ASME UV-certified valves
- !Individual test documentation needed for inspections and commissioning
- !System pressures vary widely across refrigerant types and design conditions
- !Large chiller plants require standardized valve specifications across multiple circuits
Why Cyrus Shank
- ASME UV stamps and individual test certificates for every valve
- Custom pressure settings to match your mechanical engineer's specification
- Compatible with R-134a, R-410A, R-1234ze, and other HVAC refrigerants
- Standardized kits available for multi-circuit chiller plants
- Fast lead times with traceable documentation packages
