The primary purpose of a solenoid valve in a refrigerant liquid line is to prevent flow into the evaporator during the off cycle. On multiple systems, a solenoid valve may be used in each liquid line leading to the individual evaporators. A liquid line solenoid is just a valve that opens and closes, it has a magnetic coil and depending on whether the valve is normally open or normally closed it opens or closes when the coil is energized. The MOPD is largely determined by the solenoid valve type, but it also depends on the coil that is used.
This factor is not a problem if the valve is used in the liquid line with normal cooling operation. Find great deals on eBay for liquid line solenoid valve.
With this information, the correct valve can be selected from the Selection Tables. For Liquid Line capacity data, see Page and and individual specification pages. For Suction Line capacity data, see capacity tables Page and 7. For Discharge Gas capacity data, see capacity tables Page and 7. All solenoid valves are tested and rated in.
Liquid line solenoid valve products are most popular in Domestic Market, Mid East, and Eastern Asia. In direct-acting solenoid valves, the plunger opens and closes an orifice inside the valve.
