York S1-1TVMCA1 TXV Kit

When you are upgrading or maintaining a split system, the York S1-1TVMCA1 is the professional-grade solution for managing superheat in older R-22 refrigerant units. This genuine OEM thermal expansion valve (TXV) kit is optimized for 1.5 to 2.5-ton applications, specifically for York air handlers and indoor coils like the CM, CF, and CU series. Engineered with a 3/4-inch Chatleff connection, this bolt-on valve facilitates a secure, leak-free mechanical seal without requiring complex brazing at the distributor, saving significant time during a field conversion or component replacement.

The S1-1TVMCA1 TXV kit includes an internal check valve, making it fully compatible with both cooling-only and heat pump cycles. By precisely modulating refrigerant flow based on evaporator load, it prevents liquid slugging and ensures the compressor operates within safe parameters. Every kit comes complete with a sensing bulb, bulb straps, 2.5 feet of thermal insulation, and a Teflon washer to ensure a complete and successful install. For technicians working on HVAC 1.5-2.5 ton systems, using this York-certified part is essential for restoring factory-rated efficiency and achieving stable suction line pressure.

Key Benefits for Contractors:

• Universal Compatibility: Works with York family brands including Luxaire, Coleman, and Champion R-22 equipment.
• Field-Proven Reliability: The thermal expansion valve features a bolt-on design that eliminates the risk of overheating internal components during installation.
• Enhanced Flow Control: Specifically calibrated for R-22 expansion valve applications to maintain optimal superheat and maximize coil heat transfer.
• Installation Ready: Includes an external equalizer line and everything needed for a seamless retrofit from fixed orifice to TXV.

Common Questions:

Is the S1-1TVMCA1 compatible with R-410A systems?
No, this kit is specifically designed for R-22 refrigerant. Using it with R-410A will result in incorrect flow rates and potential system damage.

Does this kit require a hard start kit?
When adding a TXV to a system that previously used a fixed orifice, a hard start kit is often recommended to assist the compressor during the initial pressure equalization process.

Can I use this on a 3-ton evaporator coil?
This specific model is sized for 1.5 to 2.5 tons. For 3-ton systems, the S1-1TVMCB1 is the appropriate match to ensure proper refrigerant metering.
