When you need to replace a refrigeration solenoid valve, Grainger carries the right one for your system, plus the solenoid coil to match. Regulate your refrigerant with a thermostatic expansion valve, and put in a filter-dryer to keep it in good condition. Even install a new refrigerant line if you're doing a serious rebuild. Come to Grainger for reliable HVACR supplies. Refrigeration solenoid valves can be used with all CFC, HFC and HCFC refrigerants but are not for use with ammonia.
