Emerson Flow Control (Alco) 047521 Valve Less Coil 1/2" SAE N/C 200RB

The Emerson Flow Control (Alco) 047521 Less Coil solenoid valve is intended to be used in refrigeration and air conditioning applications. This normally closed N/C valve, with the actual metric size of 1/2 inch SAE connection, regulates refrigerant flow. When energized, the valve opens and refrigerant flows through the valve. It stays closed when de-energized. Such detailed control enhances system’s effectiveness and productivity. Valve Less Coil design enables to choose and fit a coil of the desired voltage and application for use, hence flexibility. Advantages of this valve include increased system effectiveness, decreased energy use, and increased reliability.
