Aaon V29710 Valve

The Aaon V29710 is a high-performance BBIZE-6-B15-GA TXV Valve engineered for precise refrigerant metering in commercial HVAC systems. This balanced port thermostatic expansion valve is the direct engineering replacement for the legacy Aaon R15770, ensuring seamless mechanical compatibility during field retrofits. Designed to handle varying head pressures and load fluctuations, the V29710 maintains optimal evaporator superheat across a wide operating range, preventing liquid slugging and protecting the compressor. Its internal check valve and robust construction make it ideal for heat pump and cooling-only applications where reliable refrigerant flow control is critical. For technicians servicing Aaon rooftop units or chillers, this Aaon replacement TXV provides the exact OEM specifications required to restore factory-standard efficiency. The valve's design minimizes seat erosion and provides stable modulation, ensuring the HVAC expansion device performs under high-demand commercial HVAC maintenance cycles without hunting or premature failure.
