Description
The York S1‑1TVMBD1 is an OEM Thermostatic Expansion Valve (TXV) Kit for HVAC / air‑conditioning / heat‑pump systems that use R‑410A refrigerant. It’s designed to precisely regulate the flow of refrigerant into the evaporator coil, adjusting dynamically based on load conditions and temperature — which helps optimize cooling performance, improve energy efficiency, and protect the system from refrigerant mis‑distribution (too much or too little refrigerant flow).
Key Features
- Refrigerant: R‑410A compatible
- Connection Type: ¾‑inch Chatleff connector — standard for many split‑system coils and air‑handlers.
- Includes: Valve body + internal check valve, ~2.5 ft thermal insulation wrap, bulb clamp/straps, Teflon washer, installation instructions / hardware.
- Function: Regulates refrigerant flow into the evaporator coil based on load/temperature — ensures proper refrigerant vaporization and keeps suction-line pressures correct, preventing issues like liquid slugging or inefficient cooling.
- Application: Designed for compatible indoor coils and air‑handler units (e.g. coil models CF, CM, CU and air‑handler models AP, AE, AVC, among others) when matched with an appropriate outdoor condensing unit.
- System Size Compatibility: Typical use for split‑system air conditioners and heat pumps — commonly for residential to light‑commercial tonnage (verify coil/condensing unit specs for exact match).
