Daikin-McQuay 030569101 TXV

As a veteran HVACR technician, you know that field reliability starts with precise refrigerant metering. The Daikin-McQuay 030569101 TXV is a heavy-duty, 20-ton thermostatic expansion valve engineered specifically for high-capacity R22 refrigerant systems. Featuring a 7/8" ODF inlet and a 1 3/8" ODF outlet, this mechanical valve ensures optimal superheat control across varying load conditions, preventing liquid slugging and protecting the compressor in large-scale commercial or industrial setups. The 60-inch capillary tube provides the necessary reach for secure bulb placement on the suction line, even in complex Daikin-McQuay HVAC air handler configurations. This OEM expansion valve is a direct drop-in replacement for part numbers 305691A-01 and 072195007, often utilized in power head assemblies like the KTY735-VCP100 to maintain high-efficiency thermal exchange in aging R22 infrastructure.

Key Benefits

• Precise Superheat Management: Maintains a consistent evaporator pressure-temperature relationship to maximize thermal efficiency and system longevity.
• High-Capacity 20-Ton Rating: Optimized for large-tonnage commercial air conditioning and industrial process cooling.
• OEM Compatibility: Guaranteed fit for McQuay 030569101 specifications, eliminating field-modification headaches during emergency repairs.
• Extended 60" Capillary: Offers superior flexibility for bulb mounting, ensuring accurate sensing even in cramped evaporator cabinets.
• Rugged Brass Construction: Built to withstand high-vibration environments common in heavy-duty rooftop units and chillers.

Common Questions

What are the exact connection sizes for the 030569101?
This valve features a 7/8" ODF (Solder) inlet and a 1 3/8" ODF (Solder) outlet, designed for high-flow suction and liquid lines.

Is this TXV compatible with R410A?
No, this specific model is calibrated strictly for R22 refrigerant systems. Using it with R410A will lead to incorrect metering and potential system failure.

Does this include the power head?
Yes, the 030569101 is a complete thermostatic expansion valve assembly integrated with a 60-inch capillary and sensing bulb.
