Description
The Daikin-McQuay 106489123 is an OEM thermostatic expansion valve (TXV) engineered for precise refrigerant metering in Daikin-McQuay commercial and applied HVAC systems. Featuring an external equalizer design, this valve accurately responds to evaporator outlet superheat conditions, ensuring stable system performance across varying load conditions.
Key Features
- 5/8″ ODF liquid-line inlet connection for reliable, leak-free installation
- 1/2″ ODF suction-line outlet connection
- External equalizer port for accurate superheat sensing in longer evaporator circuits
- 5-foot capillary tube for flexible bulb placement and routing
- OEM Daikin-McQuay replacement part — direct-fit for compatible applied equipment
Why Use a TXV with External Equalizer?
An external equalizer connects the TXV sensing element directly to the evaporator outlet pressure, bypassing pressure drop across the evaporator coil. This is essential in systems with multi-circuit or longer evaporator coils where internal equalizer designs would result in improper superheat control, reduced efficiency, or potential compressor flooding.
