Trane VAL2980 TXV

For high-capacity R22 service work, the Trane VAL2980 is a critical 5 ton TXV designed for precise refrigerant metering. This thermostatic expansion valve (TXV) is engineered to maintain optimal superheat across varying load conditions, ensuring the evaporator coil operates at peak efficiency. Featuring 1/2" x 1/2" ODF (Outside Diameter Fitting) solder connections, this valve provides a secure, leak-free braze joint for standard copper linesets. As a veteran-grade refrigerant flow control component, it helps prevent liquid slugging and compressor damage in large residential and light commercial systems. The VAL2980 is a direct replacement for many older 5-ton Trane and American Standard units, offering a localized solution for maintaining legacy R22 systems without the need for immediate equipment conversion.

• Optimized Efficiency: Precise metering ensures ideal refrigerant saturation in the evaporator, maximizing cooling output.
• System Protection: Actively manages superheat to protect the compressor from liquid floodback.
• Heavy-Duty Construction: Built with high-grade brass and stainless steel components for long-term reliable service in the field.
• Universal Compatibility: Standard 1/2-inch sweat connections facilitate straightforward installation on most 5-ton R22 air handlers and cased coils.

Is the VAL2980 compatible with R410A systems?
No, this valve is specifically calibrated for the pressure-temperature characteristics of R22 refrigerant. Using it with R410A will result in incorrect metering and potential system failure.

Does this valve include an external equalizer?
The Trane VAL2980 typically features an external equalizer connection (0.25 ODF) to compensate for pressure drops across high-capacity evaporator coils, ensuring accurate sensing at the coil outlet.

Can I use this TXV on a 3-ton or 4-ton system?
This valve is sized specifically for 5-ton cooling capacities. Undersizing or oversizing a TXV can lead to hunting, poor oil return, or evaporator freezing; always match the tonnage to your equipment specifications.
