Trane VAL8613 TXV

The Trane VAL8613 is a high-performance thermostatic expansion valve (TXV) designed for 5-ton R-22 HVAC systems. Engineered for precision refrigerant metering, this mechanical fitting TXV ensures stable superheat levels in both air handler and heat pump applications. It features 5/8" ODF inlet and outlet connections, specifically designed for seamless integration with legacy R-22 refrigerant circuits requiring accurate flow control to prevent liquid slugging and maintain evaporator efficiency. This OEM Trane replacement part (often cross-referenced as VAL08613) includes a non-bleed port and an external equalizer with a .125 OD x 20-inch capillary tube, providing the feedback needed for systems with high pressure drops across the evaporator. For technicians servicing residential or light commercial units like the 2TXCC060 or 2TXAD061 series, this 5-ton expansion valve provides the necessary 52/48 PSIG superheat setting to optimize heat exchange and protect the compressor during high-load cooling cycles.

• Optimized Efficiency: Maintains precise refrigerant flow to the evaporator, ensuring maximum heat absorption and system SEER performance.
• Broad Compatibility: Direct drop-in for Trane and American Standard 5-ton air handlers and heat pumps using R-22.
• Robust Construction: Manufactured by Sporlan for Trane, featuring durable mechanical fittings that stand up to high vibration and industrial use.
• Compressor Protection: Prevents refrigerant floodback by maintaining a consistent superheat, extending the service life of the 5-ton reciprocating or scroll compressor.

Is the VAL8613 a bleed or non-bleed type valve?
This is a non-bleed expansion valve, meaning it closes completely when the compressor cycles off, preventing high-to-low side pressure equalization and improving startup efficiency.

Can I use this TXV on an R-410A system?
No, the VAL8613 is specifically calibrated for the pressure-temperature characteristics of R-22 refrigerant. Using it with R-410A will result in improper metering and potential system failure.

Does this kit include the mechanical fittings?
Yes, this VAL08613 kit is typically supplied with the necessary mechanical fittings for the 5/8" line set, allowing for a secure connection without always requiring brazing at the valve body.
