Description
The Copeland 1838420 is a normally closed (NC), 2-way solenoid valve designed for refrigeration and HVAC systems requiring dependable, electrically actuated refrigerant flow control. Featuring a 7/8″ sweat (SWT) connection, this valve integrates seamlessly into copper refrigerant line installations, making it a go-to choice for commercial refrigeration, air conditioning, and heat pump applications.
In its de-energized state, the valve remains closed, preventing refrigerant flow and protecting the system during off-cycles or emergency shutdowns. When energized, the valve opens to allow precise refrigerant flow, supporting efficient system operation and temperature management.
