Johnson Controls A-4400-607 Replacement Drain Valve

Ensure consistent moisture removal and system reliability with the Johnson Controls A-4400-607 Replacement Drain Valve. This authentic OEM HVACR replacement part is engineered specifically for Johnson Controls A-4000 Series air dryers manufactured with a date code after 9923. Designed for pneumatic air dryer maintenance, this valve provides critical water flow management to prevent condensate carryover in downstream pneumatic lines, protecting sensitive instrumentation from corrosion and failure.

The A-4400-607 is critical for technicians servicing A-4000-156 and A-4000-158 condensate drains. Its corrosion-resistant construction is built to withstand industrial environments, operating efficiently across a temperature range of -10 to 140°F. Integrating this high-performance pneumatic drain valve ensures your compressed air system maintains its specified dew point by clearing accumulated liquids without pressure loss. For contractors, specifying the correct date-code-sensitive drain valve is essential for a seamless first-time fix and long-term system integrity.

Key Benefits for Technicians:

• Compatible with Johnson Controls A-4400 air dryer units and A4000-156/158 condensate drain systems.
• Optimized for post-9923 date code configurations for exact mechanical fit and performance.
• Robust corrosion-resistant housing increases longevity in high-moisture pneumatic applications.
• Maintains system integrity by ensuring automated and reliable condensate expulsion.
• Simplifies field repairs with direct-fit OEM specs, reducing diagnostic and installation time.

Common Questions:

Is the A-4400-607 compatible with older A-4000 dryers?
No, this specific valve is designed for units produced after the 9923 date code. For models manufactured prior to 9923, the A-4110-607 is typically the required part. Always verify the date code on the dryer's nameplate before ordering.

What systems use the A-4400-607 drain valve?
It is primarily used in Johnson Controls pneumatic control systems where an A-4000-156 or A-4000-158 condensate drain assembly is installed to manage moisture in the air supply.

Can this valve be rebuilt?
While some pneumatic components have seal kits, veteran technicians usually recommend a full replacement of the A-4400-607 to ensure reliable operation, as internal wear from particulate matter can compromise the valve's seating over time.
