Ammonia-compatible, ASME-certified relief valves for food and beverage processing refrigeration systems.
Series 850
Zero-Downtime Valve
250–400
PSI Range
SS Internals
Ammonia Compatible
ASME UV
Certified
Application Overview
Food and beverage processing facilities run large ammonia refrigeration systems that demand pressure relief valves with stainless steel internals, ASME UV stamps, and the ability to operate continuously under USDA-regulated conditions. The Series 850 dual relief assembly is widely specified in processing plants where in-service valve maintenance is required without system shutdown.
Common Challenges
- !USDA regulations require continuous refrigeration — no system shutdowns for maintenance
- !Ammonia (R-717) requires stainless steel internals for corrosion resistance
- !High system pressures up to 400 PSI demand heavy-duty valve construction
- !ASME code compliance required for all pressure-bearing components
Why Cyrus Shank
- Series 850 dual relief allows valve service without system shutdown
- Stainless steel internals standard for ammonia compatibility
- Custom set pressures from 50–400 PSI, individually tested
- ASME UV-stamped with individual test certificates
- Proven in large-scale food and beverage processing plants nationwide
