Armstrong International A23519 Valve

The Armstrong International A23519 is a direct replacement solenoid fill valve engineered specifically for EHU-600 and EHU-701 electronic steam humidifier series. This OEM humidifier component features an integrated flow washer for precise water volume regulation and is equipped with a straight 3/8" compression fitting to ensure a leak-free connection to the supply header. Designed to withstand the high-temperature cycles common in industrial steam humidification, the A23519 manages water intake with high seat integrity, preventing mineral bypass and scale accumulation at the inlet. For field technicians, this valve simplifies humidifier maintenance by utilizing a standard electrical interface and rugged housing that resists mechanical fatigue. Whether servicing an existing Armstrong EHU humidifier or performing a preventative overhaul, using this HVAC replacement part ensures the system maintains the correct water level in the canister, optimizing moisture output and protecting the internal electrodes from dry-fire conditions.

• Direct Compatibility: Precision-fit for Armstrong EHU-600 and EHU-701 series steam humidifiers.
• Integrated Flow Control: Pre-installed flow washer maintains consistent GPM regardless of fluctuating inlet pressures.
• Simplified Installation: Straight 3/8" compression fitting allows for quick attachment to standard copper or plastic tubing.
• Industrial Durability: Engineered to handle high-duty cycles in commercial HVACR environments.

Is this fill valve compatible with the older EHU-500 series?
The A23519 is specifically designed for the EHU-600 and EHU-701 models. Check the humidifier's technical data plate to confirm the prefix before installation.

Does this assembly include the flow restrictor?
Yes, this replacement fill valve includes the internal flow washer to regulate water velocity into the cleaning tank.

What is the primary indicator that the A23519 needs replacement?
Common failure points include mineral blockage in the 3/8" compression fitting or an energized coil that fails to actuate the plunger, leading to water level errors on the humidifier controller.
