Duratech DURAPRO-12/17/21 R32 3-Way Valve

This genuine Duratech 3-way valve is a replacement component for DURAPRO-12, DURAPRO-17, and DURAPRO-21 heat pump units running R32 refrigerant. As part of the refrigerant circuit, this valve plays an important role in directing flow within the system.

What Does a 3-Way Valve Do?

A 3-way valve manages refrigerant flow between three connection points within the heat pump circuit. Depending on its position, it directs refrigerant along different paths, enabling functions such as bypassing certain components, managing defrost operations, or controlling system modes. The precise role varies depending on where the valve sits within the overall system design.

Signs of Valve Failure

Symptoms of a failing 3-way valve can include the heat pump not switching modes correctly, inefficient heating performance, error codes related to refrigerant flow or pressure, or the system behaving erratically during certain operating conditions. Because valve issues can mimic other faults, proper diagnosis is important to confirm the valve is the problem before replacement.

R32 Compatibility

This valve is designed specifically for R32 refrigerant systems. Components in R32 heat pumps are engineered to work with the characteristics of this refrigerant, so using the correct part is essential for safe and efficient operation.

Professional Installation Required

Any work on the refrigerant circuit requires a qualified engineer with F-Gas certification. The system must be safely recovered before removing the old valve, and recharged and tested after fitting the replacement. Attempting this work without proper training and equipment risks damage to the heat pump and potential safety hazards.
