Mcquay Daikin 106484002 Valve

The McQuay Daikin 106484002 Expansion Valve is a critical metering device designed for precise refrigerant flow control in 0.75-ton HVAC systems. Engineered for specific compatibility with McQuay and Daikin water source heat pumps and fan coil units, this thermostatic expansion valve (TXV) features a 3/8-inch inlet and a 1/2-inch outlet connection. By dynamically adjusting the orifice based on cooling load requirements, it maintains optimal superheat levels, preventing liquid slugging and protecting the compressor from premature failure. This OEM replacement valve ensures the system operates within original factory specifications, maintaining energy efficiency and heat transfer rates. For technicians performing HVAC troubleshooting on 3/4-ton light commercial units, this valve provides the exact pressure drop and flow rate needed to stabilize suction pressure across varying ambient conditions.

• Precise Superheat Control: Maintains exact refrigerant regulation to maximize evaporator coil efficiency.
• Direct OEM Fit: Drop-in replacement for McQuay 106484002, eliminating the need for field piping modifications.
• System Protection: Actively prevents liquid refrigerant from returning to the suction line.
• Durable Construction: Built to withstand high-pressure fluctuations in R-410A or R-22 applications depending on system configuration.

What are the connection sizes for the 106484002 valve?
