Bard part number 5651-248BX is an OEM electronic expansion valve (EEV) assembly listed as EEV E2V30, supplied boxed for service replacement. This metering device is used in compatible Bard wall-mount and packaged systems to precisely regulate refrigerant flow into the evaporator so the unit can maintain stable superheat and reliable cooling performance under changing load conditions. Replacing a faulty EEV can help address symptoms like erratic suction pressure, poor capacity, coil freeze-up, or control faults tied to unstable refrigerant feed, but correct selection matters since EEVs are matched to the specific model, refrigerant circuit, and control strategy. Verify compatibility by matching the Bard part number 5651-248BX to your unit model and serial, and confirm any required driver/controller and wiring connections before installation.
Bard uses suffixes like "BX" to manage parts internally. These do not change the physical form or function of the part.
A part number ending in "BX" simply means it is packaged in a box for shipping, rather than for internal assembly use.
Example: 8406-142BX is physically identical to 8406-142.
