Trane VAL4911 TXV

When you're servicing a 7.5-ton system built for R-22 refrigerant, precision in superheat adjustment Is non-negotiable. The Trane VAL4911 TXV is a field-proven thermostatic expansion valve engineered to maintain optimal evaporator efficiency. Featuring a 1/2-inch inlet and a 7/8-inch outlet with sweat connections, this valve provides a secure, leak-resistant fit. The 60-inch capillary tube offers the necessary reach for flexible remote bulb placement, ensuring accurate thermal sensing and rapid response to load changes. As an authentic OEM HVAC replacement part, the VAL4911 (also referenced as VAL04911) eliminates the guesswork associated with generic alternatives, ensuring the flow rate and pressure drops match the original engineering of the air handler or rooftop unit. This 7.5-ton expansion valve is a critical component for restoring system stability and preventing compressor slugging in legacy commercial or high-capacity residential applications.

• Precise Refrigerant Control: Specifically calibrated for R-22 refrigerant to manage liquid flow and protect the compressor.
• Extended Capillary Reach: The 60-inch capillary provides ample length for proper bulb positioning on the suction line.
• Durable Brass Construction: Built to withstand commercial operating pressures and thermal cycling without fatigue.
• Direct OEM Compatibility: Ensures an exact mechanical fit for Trane and American Standard 7.5-ton equipment.
• External Equalizer: Features a 1/4-inch SAE external equalizer to compensate for pressure drops across the evaporator coil.

Is the VAL4911 compatible with R-410A systems?
No, this valve is strictly designed for R-22 refrigerant systems. Using it with R-410A will lead to improper superheat and potential system failure due to different pressure-temperature characteristics.

Does this TXV include the O-rings or mounting hardware?
This is a sweat-connection valve (ODF). While the valve includes the remote bulb and capillary, standard brazing supplies and specialized HVAC technician tools are required for installation.

Can I use this on a 5-ton or 10-ton unit?
The VAL4911 is rated specifically for 7.5-ton capacity. Oversizing or undersizing the TXV will result in hunting or evaporator flooding; always match the tonnage to the indoor coil specifications.
