Supco SUHS24 Humid Solenoid
Professional-grade Supco SUHS24 Humid Solenoid is a universal humidifier solenoid valve engineered for immediate field replacement of high-failure OEM components. Operating on a standard 24V humidifier valve circuit, this kit is designed to restore moisture control in residential HVAC bypass and power humidifiers. The SUHS24 solenoid is a direct cross of 4357 and provides a precise fit for the A01-0814-148, ensuring your system maintains target humidity levels without the cost of brand-specific parts.
For technicians in the field, the Supco SUHS24 eliminates the need for multiple stock parts. It effectively replaces Aprilaire 4040, Honeywell 320016939-002, and General 990-53 valves. The package includes a heavy-duty mounting bracket and various compression fittings to accommodate current water line diameters. This HVAC humidifier part utilizes a 24-volt AC coil that actuates the internal plunger, managing water flow to the distribution tray. Built for durability, it handles standard line pressures and resists mineral scale buildup, though it is not intended for systems requiring internal metering orifices.
- Universal Compatibility: Drops into most bypass and power humidifier setups, including those from Aprilaire, Skuttle, and GeneralAire.
- Complete Install Kit: Includes the valve, bracket, and necessary fittings for a fast, wrench-in installation.
- Contamination Resistance: Engineered to withstand the rigors of hard water and high-use heating seasons.
- Direct OEM Replacement: Replaces specific legacy numbers like 4357, A01-0814-148, and 320016939-002 with identical 24V specs.
Can the SUHS24 be used on 120V systems?
No, this is specifically a 24V AC component. Applying higher voltage will immediately burn out the solenoid coil. Always verify transformer output before wiring.
Why is the valve constantly running even when the furnace is off?
Continuous water flow usually indicates either a stuck plunger due to mineral deposits or a faulty humidistat relay that is staying energized. Check for 24V at the wires; if no power is present and water still flows, the valve seat is compromised and requires replacement.
Does this valve include a built-in strainer?
While the SUHS24 is built for debris resistance, we recommend verifying the presence of an inline strainer in your water feed line to prevent sediment from clogging the 24V orifice.
