Bohn 29300013 Thermostatic Expansion Valve Txv

Product Description

The BOHN 29300013 is a thermostatic expansion valve (TXV) designed for use in commercial refrigeration systems. The TXV meters refrigerant flow into the evaporator coil, maintaining the correct superheat level to protect the compressor and maximize system efficiency. This valve carries the Heatcraft parts designation VAK08AG and is sourced as a genuine Heatcraft commercial appliance component. Licensed refrigeration technicians and commercial HVAC-R service professionals install this part during system commissioning, routine maintenance, or valve replacement service.

This TXV is intended for commercial refrigeration applications where precise refrigerant metering is required. Typical installations include walk-in coolers, walk-in freezers, reach-in display cases, and other commercial evaporator systems that fall within the Heatcraft product lineup. The valve regulates refrigerant flow in response to suction line temperature and pressure, maintaining stable evaporator performance across varying load conditions.

Compatibility

Designed as an OEM-style replacement TXV for Heatcraft commercial refrigeration evaporator systems carrying the VAK08AG valve designation. Consult the equipment nameplate and service documentation to confirm compatibility before installation.

Installation Notes

TXV replacement and service must be performed by an EPA Section 608 certified refrigeration or HVAC-R technician. Before beginning work, recover all refrigerant from the system in accordance with EPA regulations and shut off all electrical power to the unit. Proper brazing practices, leak testing, evacuation to the required micron level, and recharge to the manufacturer-specified refrigerant type and weight are required after valve replacement. Do not reuse old flare fittings or ferrules during reinstallation.
