Lennox 11Y30 Expansion Valve
Professional-grade Lennox 11Y30 Expansion Valve stands as a critical 4-ton R410A expansion valve engineered for precision refrigerant metering in high-efficiency residential and light commercial HVAC systems. This thermal expansion valve (TXV), manufactured for Lennox by Danfoss (Part No. 104413-02), is designed to optimize evaporator heat transfer by maintaining a precise superheat setpoint across varying load conditions. It features an integrated check valve functionality, making it essential for heat pump applications where bi-directional flow control is required during heating and cooling cycles.
The Lennox 11Y30 TXV utilizes an external equalizer to compensate for pressure drops within the evaporator, ensuring the system operates at peak thermodynamic efficiency. Built with durable brass and stainless steel components, this HVAC expansion valve handles high-pressure R410A environments up to 711 psig. For technicians, the 11Y30 delivers consistent liquid refrigerant flow, preventing compressor floodback and "hunting" behaviors that lead to premature component wear. Whether performing a Lennox TXV replacement or a new 4-ton system install, this OEM valve ensures factory-spec performance and reliable oil return to the compressor.
Key Benefits- Optimized Refrigerant Control: Delivers precise 4-ton capacity metering specifically for R410A systems to maximize EER/SEER ratings.
- Integrated Check Valve: Simplifies heat pump installations by allowing reverse flow without additional external piping.
- Superior System Protection: Maintains stable superheat to prevent liquid slugging and extend compressor life.
- OEM Compatibility: Genuine Lennox replacement for part numbers 104413-02 and 119F7731, ensuring exact fit and manifold alignment.
- High Pressure Rating: Engineered for the rigorous demands of R410A with a maximum working pressure of 49.0 bar (711 psig).
- How do I verify if the Lennox 11Y30 is "hunting"? Check for rapid fluctuations in suction pressure and superheat. Hunting usually indicates an oversized valve or a poorly positioned sensing bulb. Ensure the bulb is mounted at the 2 o'clock or 4 o'clock position on the suction line.
- Can this be used on a 3.5-ton system? While designed for 4-ton units, minor adjustments to the superheat stem may allow application in slightly smaller loads, but always verify subcooling and evaporator saturation temperatures first.
- Does this valve solve low suction pressure issues? If the TXV is stuck closed or the sensing bulb has lost its charge, suction pressure will drop. Confirm the inlet screen is clear of debris before replacing.
