The RCZE valve is an externally adjustable
balance ported TEV with an internal
check valve for heat pump applications. This
makes the RCZE valve an excellent replacement
for all OEM CBI and CBBI valves as

RCZE
well as other applications requiring a R-410A expansion valve on heat
pumps. The RCZE valve may also be used on air conditioning (cooling
only) applications. This allows you to reduce inventory to also
replace the I, RI, BI and BBI valves. The RCZE valves utilize the
KT-45 element design for the higher pressures of R-410A systems.
