York S1-025-31963-000 TXV

The York S1-025-31963-000 TXV is a critical OEM thermostatic expansion valve engineered for precise refrigerant metering in specialized HVACR applications. Featuring 3/8 x 5/8 ODF (Outside Diameter Female) sweat connections, this valve is designed to maintain the optimal superheat required for system stability, specifically targeting R-22 refrigerant service. It functions as the dividing point between the high-pressure liquid line and the low-pressure evaporator, dynamically adjusting flow to prevent liquid slugging and compressor floodback. As a genuine York replacement part, it ensures exact fitment for compatible units such as the DH060N10P2AAA3 series, maintaining the pressure drop characteristics required for high-efficiency cooling. For technicians servicing legacy refrigeration sets or specific residential split systems, this refrigerant flow control component provides the necessary sensitivity to load changes, ensuring the evaporator coil remains fully active without risking mechanical failure at the compressor head.

• OEM Compatibility: Guaranteed fit for York and Johnson Controls brands, eliminating the need for field modifications on 3/8 x 5/8 ODF lines.
• Precise Superheat Control: Maintains exact refrigerant levels in the evaporator to maximize heat transfer efficiency.
• System Protection: Actively prevents liquid refrigerant from returning to the compressor, extending the operational life of the system's "heart."
• R-22 Specific Calibration: Calibrated for the specific pressure-temperature relationship of R-22 refrigerant systems.

Is this TXV compatible with R-410A systems?
No, this specific model is designed and calibrated for R-22 refrigerant. Using it with R-410A will lead to incorrect metering due to the significant difference in operating pressures.

Does this valve require a separate sensing bulb?
This is an integrated thermostatic expansion valve assembly that includes the necessary sensing element to monitor suction line temperature for real-time adjustments.

What does the 'ODF' connection type signify for installation?
ODF stands for Outside Diameter Female, meaning the unit is designed for a sweat/braze connection where the copper tubing slides into the valve ports.
