In industrial ammonia (R-717) refrigeration systems, choosing the right valve isn’t just a design preference; it’s a safety-critical decision. Ammonia is toxic, mildly flammable, and typically flows through the system at elevated pressures while constantly shifting between liquid and vapor phases.

Understanding how globe valves, ball...
