Section III. REPAIR OF REFRIGERANT SYSTEM VALVES
7-17. General
a.
The rebuilding and/or replacement of the refrigerant control valves and high-low pressure switch are discussed in
this section. The valves discussed are: the solenoid valve, liquid quench valve, hot gas bypass valve, the thermostatic
expansion valve, and pressure relief valve.
b.
Since the valve bodies do not generally require replacement, the valves are rebuilt in
7-9
