Aaon R15730 Thermostatic Expansion Valve 3/8" x 7/8" ODF

The Aaon R15730 is a genuine OEM thermostatic expansion valve (TXV) designed for commercial HVAC refrigeration systems. This precision-engineered valve features 3/8" inlet and 7/8" outlet ODF (Outward Drawn Flare) copper connections, making it compatible with Aaon rooftop units and air conditioning equipment.

Key Features:

• 3/8" x 7/8" ODF copper tube connections for direct brazed installation
• Thermostatic sensing bulb regulates refrigerant flow based on superheat
• Maintains optimal evaporator efficiency and system performance
• Precision-machined brass body for durability and long service life
• Factory calibrated for accurate refrigerant metering
• Direct replacement for Aaon commercial rooftop units and packaged systems

This TXV controls the flow of liquid refrigerant entering the evaporator coil by sensing superheat at the coil outlet, ensuring the evaporator operates at peak efficiency while preventing liquid floodback to the compressor. Essential for maintaining proper system operation in commercial refrigeration and air conditioning applications.
