Description
The AAON V36640 is a genuine OEM thermostatic expansion valve (TXV) engineered specifically for AAON HVAC equipment. Featuring 5/8″ and 7/8″ ODF (Outside Diameter Flare) connections, this valve provides accurate, responsive refrigerant metering to maintain optimal evaporator superheat — a critical factor in system efficiency, compressor protection, and overall equipment longevity.
Key Features
- Genuine AAON OEM replacement part — ensures proper fit and performance
- 5/8″ inlet x 7/8″ outlet ODF connections for straightforward field installation
- Thermostatic expansion valve design for precise refrigerant flow control
- Maintains optimal evaporator superheat to protect the compressor
- Helps maximize system efficiency and reduce energy consumption
- Built to AAON quality standards for reliable, long-term operation
Why Choose a Genuine OEM TXV?
Using a factory-specified TXV ensures the valve is calibrated to the exact refrigerant charge, evaporator coil size, and operating conditions of your AAON unit. An improperly matched expansion valve can lead to poor superheat control, liquid slugging, or reduced capacity — all of which shorten equipment life and increase operating costs. The V36640 eliminates guesswork and keeps your AAON system running as designed.
Application
- Direct OEM replacement for compatible AAON rooftop units and air handlers
- Suitable for use in commercial HVAC refrigeration circuits
