Pressure Regulator- A4 Dual Outlet A473E500A2A7S50B11YXSN

These A4 regulators are compact, heavy duty, pilot operated, iron alloy Outlet Pressure regulators.

The A4 Outlet Pressure Regulator modulates flow of refrigerant gas or liquid to maintain a constant downstream pressure as set-for, despite fluctuations in load. The regulator will gradually close when downstream pressure begins to rise above the setting and will gradually open when pressure begins to fall below the setting. These valves are generally ordered with close coupled strainer to prevent entrance of foreign material into the valve and the rest of the system.
