Description
The Daikin-McQuay 910179370 is an OEM thermostatic expansion valve (TXV) engineered for precise refrigerant flow control in compatible Daikin-McQuay HVAC and refrigeration systems. Thermostatic expansion valves are a critical component in the refrigeration cycle, automatically metering the flow of liquid refrigerant into the evaporator coil to maintain optimal superheat levels — protecting the compressor and maximizing system efficiency.
Key Features
- OEM Daikin-McQuay replacement TXV for direct-fit installation
- Automatically meters refrigerant flow to maintain proper superheat
- Helps protect the compressor from liquid slugging
- Supports consistent system efficiency and cooling capacity
- Designed for compatibility with Daikin-McQuay equipment using this OEM part number
Why Choose an OEM TXV?
Using a genuine OEM thermostatic expansion valve ensures proper fit, calibration, and performance within your Daikin-McQuay system. Aftermarket substitutes may not match the factory-specified superheat setting or connection dimensions, potentially leading to reduced efficiency or equipment damage. The 910179370 is the manufacturer-specified replacement, giving technicians confidence in every installation.
