Refrigeration Valves
10 productsEvery circuit needs valves: to isolate a component for service, to drop pressure into the evaporator, to stop flow when the compressor stops. This group covers all four jobs — ball and hand valves for manual isolation, check valves for one-way flow, solenoid valves for automatic on/off, and thermostatic expansion valves for metering. The range also includes Maneurop and Rotalock style stop valves for compressor changeover, and service valves with a charging port for split air-conditioning work. When selecting, the line size is only the starting point. Check the Kv value against the flow you expect at the pressure difference available, confirm the connection style (flare SAE, solder ODF, or a threaded compressor stub), and make sure the temperature rating covers the line it sits on — a suction line valve sees very different conditions from one on the liquid line.
