About: Alpine Hardware is a replacement humidifier solenoid valve manufactured for most humidifiers. The solenoid valve turns water on and off to your humidifier but does not regulate volume which is done by a different part called an orifice. Contains pre-installed strainer in the inlet side of the valve for capturing clogging elements in the water such as dirt and sand. Uses pre-existing compression fitting on the outlet side. Electrically operated and uses 24 volts and 2.3 watts. Manufacturer of this valve recommends that any wiring on your humidifier be completed by a professional contractor.
