Mueller Type Refrigeration Magnetic Check Valve 1/4'' to 3 1/8'' Solder
Magnetic type refrigeration check valve is designed for installation in commercial refrigerating systems and in residential or industrial air conditioning plants. They are used to control the unidirectional flow of refrigerant to prevent backflow; the magnetic actuator guarantees a high reliability standard. When you install the refrigeration check valve in the system, it will rapidly balance the high pressure and low pressure inside of the compressor when the compressor stops working, when it reaches balance, then the refrigerants won't flow until the air conditioning or the refrigeration unit restarts.
