Daikin-McQuay 032189304 Valve

The Daikin-McQuay 032189304 Valve is a heavy-duty 7/8" liquid line solenoid valve engineered for precise refrigerant flow control in commercial HVACR systems. Operating at 120V, this normally closed valve features a pilot-operated mechanism designed to handle high-pressure environments up to 500 PSI. This component is a critical OEM replacement part for McQuay air-cooled chillers and rooftop units, ensuring reliable seat sealing and optimal pressure drop across the liquid line. The ODF solder connection allows for a leak-proof integration into existing copper piping, maintaining system vacuum integrity. Built for high-cycle applications, it minimizes water hammer and provides consistent actuation under varying thermal loads. Whether you are performing a liquid line drier swap or a full system overhaul, utilizing this Daikin 032189304 solenoid ensures the system operates within original design parameters without compromising compressor reliability or refrigerant velocity.

Key Benefits

• Precise Flow Regulation: Optimized for liquid line refrigerant control to prevent floodback during off-cycles.
• High Pressure Rating: Rated for up to 500# MOPD, making it compatible with high-pressure synthetic refrigerants.
• Standard Electrical Compatibility: The 120V coil configuration integrates seamlessly with most commercial control circuits and contactors.
• Direct OEM Fit: Eliminates the need for field piping modifications when replacing legacy McQuay 032189304 valves.

Common Questions

What is the connection size for the Daikin 032189304?
This valve features a 7/8" ODF (over the outside diameter) sweat connection, suitable for standard liquid line copper tubing.

Can this valve be used on suction lines?
This specific model is optimized as a liquid line valve; using it in suction applications may result in excessive pressure drop and reduced cooling capacity.

Does this assembly include the solenoid coil?
Yes, the 120V 50/60Hz coil is included with the 032189304 assembly to ensure proper magnetic flux and valve lift.
