Question

Quizplus · Accepted Answer

Stem type service valves can be closed to isolate the section of the system that contains the compressor, allowing it to be removed without losing refrigerant from the entire system. Schrader valves and R-134a style refrigerant valves are used for accessing the refrigerant system for pressure readings and adding or removing refrigerant, but they do not allow for isolation of specific parts of the system. Manifold service valves are used for connecting gauges and other tools for testing and servicing the system, but they also do not allow for isolation of specific parts of the system.
