Description
The Copeland 047504 is a direct acting, 2-way normally closed refrigeration solenoid valve body designed for reliable flow control in commercial and light commercial refrigeration systems. Featuring a 3/8″ sweat connection, this valve body provides a leak-tight, brazed installation that is ideal for professional HVAC/R technicians. The normally closed design ensures the valve remains shut in the de-energized state, providing a critical safety function that prevents refrigerant flow during power loss or system shutdown.
