Lennox 64W50 Expansion Valve

Lennox 64W50 Expansion Valve

Optimize your refrigeration or air conditioning system with the Lennox 64W50 Expansion Valve (OEM part 1000679-39). This thermostatic expansion valve (TXV) is engineered for high-performance refrigerant metering, featuring a 5-ton cooling capacity and a precisely calibrated 95 ± 2 PSIG pressure rating. Designed to maintain stable superheat control, the 64W50 ensures consistent evaporator coil performance across fluctuating load conditions. This valve is built with durable brass construction and utilizes a 3/8-inch SAE female inlet and a 1/2-inch SAE female outlet for secure, leak-resistant HVAC refrigerant flow control. As a genuine Lennox replacement part, it is optimized for compatibility with R-410A, R-22, and R-407C systems, provided the correct POE or mineral oil flushing procedures are followed. Installing this OEM expansion valve helps prevent liquid slugging and protects the compressor, ensuring the longevity and efficiency of residential split systems and light commercial rooftop units.

Key Benefits:
  • Precision Refrigerant Metering: Maintains a stable 5-ton capacity to maximize evaporator efficiency.
  • Broad Refrigerant Compatibility: Engineered for use with R-410A, R-22, and R-407C (refer to specific Lennox technical data).
  • Robust Brass Construction: Enhanced durability for demanding HVAC/R environments and industrial cooling applications.
  • Optimized Superheat Regulation: Features a minimum superheat range of 6°F to 15°F to protect against compressor damage.
Common Questions:
  • Is the Lennox 64W50 compatible with older R-422D retrofits? While designed for R-410A and R-22, compatibility depends on matching the P/T charts and ensuring oil compatibility.
  • What are the connection sizes for this valve? This unit features a 3/8" SAE female inlet and a 1/2" SAE female outlet for standard flare connections.
  • Does this TXV require an external equalizer line? Yes, the 64W50 utilizes an external equalizer port for accurate pressure sensing at the evaporator outlet.
