York S1-1TVMBG1 TXV Kit

Ensure precise refrigerant metering with the York S1-1TVMBG1 TXV Kit. This genuine OEM thermostatic expansion valve is engineered for high-efficiency R410A HVAC system parts, featuring a 3/4 inch Chatleff connection for a secure, leak-resistant mechanical seal. Designed specifically for split-system evaporators and air handlers, this thermal expansion valve kit includes a bolt-on TXV with an internal check valve, making it compatible with both cooling-only and heat pump applications. By dynamically adjusting the flow of refrigerant based on evaporator load, the S1-1TVMBG1 prevents liquid slugging and maintains optimal superheat across varying ambient conditions.

Field technicians will find this thermostatic expansion valve R410A critical for maintaining AHRI-rated performance in York, Luxaire, and Coleman equipment. The kit simplifies York TXV replacement by including 2.5 feet of thermal insulation, bulb clamps, and a PTFE washer. For proper York S1-1TVMBG1 installation, ensure the sensing bulb is mounted at the 10 o'clock or 2 o'clock position on a horizontal suction line to ensure accurate temperature sensing and reliable system operation.

• OEM Compatibility: Fits York CF, CM, CU coils and AP, AE, AVC air handlers for seamless integration.
• Enhanced Efficiency: Optimizes refrigerant vaporization to improve SEER ratings and cooling capacity.
• Mechanical Connection: The 3/4" Chatleff fitting allows for a reliable bolt-on installation without the need for brazing at the valve body.
• Bi-Flow Design: Integrated internal check valve supports bidirectional flow for heat pump defrost cycles.
• Complete Field Kit: Includes necessary hardware and insulation to ensure a professional-grade repair.

• Is a hard start kit required with this TXV? For many R410A systems, adding a hard start kit is highly recommended when moving from a fixed orifice to a TXV to assist the compressor during startup against high head pressure.
• Can this be used with R22 or R407C? No, this kit is specifically calibrated for the pressure-temperature characteristics of R410A and should not be used with other refrigerants.
• Where should the sensing bulb be placed? The bulb must be mounted on the suction line, ideally on a horizontal run, and fully wrapped with the included insulation to prevent ambient air from affecting the valve’s performance.
