Copeland Comfort Control (Alco) 030621 Solenoid Valve

The Copeland Comfort Control (Alco) 030621 Solenoid Valve (Model 210CA3/4B3/4B) is a genuine OEM two-way, normally closed industrial solenoid valve body designed for dependable air and water flow control in commercial HVAC and industrial applications. Featuring 3/4-inch female NPT connections, a 5.5 Cv flow coefficient, and a 0–125 PSI operating pressure range, this pilot-operated valve delivers reliable on/off control for higher-flow systems while minimizing pressure drop. When de-energized, the valve remains closed and opens when the appropriate solenoid coil is energized. The 030621 is supplied as a valve body only and requires a compatible Copeland solenoid coil selected for the correct system voltage. Before installation, verify the media, operating pressure, temperature, flow direction, piping size, differential pressure requirements, and coil compatibility to ensure proper operation and long-term system performance.
