Climatemaster 33B0002N06, Thermal Expansion Valve Bbive – 5, TXV

Climatemaster 33B0002N06 — Bi-Flow Thermal Expansion Valve, BIVE-5

The Climatemaster 33B0002N06 is a genuine OEM bi-flow thermal expansion valve
in the BIVE-5 size. Its job is to meter liquid refrigerant into the evaporator and modulate that
flow so the coil holds a consistent superheat across changing load conditions.

About this part

Heat pumps reverse refrigerant flow between heating and cooling, so they need an expansion
valve that can meter in one direction and pass refrigerant freely in the other. That is what the
bi-flow design does, and it is the reason a cooling-only TXV cannot be swapped in.

Capacity matters just as much as the physical fit. A valve sized for a larger tonnage will
overfeed the coil, while an undersized valve starves it, and either condition shortens compressor
life. Confirm the full part number from your unit’s parts list before ordering, and while you have
the system open, replace the liquid line filter drier at the same time.
