Carrier EF17BZ251 Reversing Valve 1/2 " x 3/4 " ODF 24V

The Carrier EF17BZ251 is a vital Reversing Valve designed for specific Carrier HVAC equipment, likely heat pumps. This key component measures roughly 7.2" long, 6.4" wide, and maintains a slim profile at 2.5" high. It operates on a standard 24-volt electrical signal. Despite its unassuming size, it plays a central role in your heat pump's ability to deliver year-round comfort. The EF17BZ251 Reversing Valve functions by changing the direction of refrigerant flow within your Carrier heat pump. In heating mode, the valve directs warm refrigerant towards the indoor unit to deliver warmth. When switched to cooling mode, the valve flips the flow, sending cool refrigerant indoors for air conditioning. This precise control of refrigerant direction is essential for efficient heat pump operation.
