ASCO 8220G29 is a 1-1/2" NPT, two-way normally closed solenoid valve from the RedHat family, designed for steam and hot-water service and driven by a 120 VAC coil. The brass-bodied valve features 1-1/2" NPT ports and a 22.5 Cv flow rating, enabling precise control in heating lines, boilers, and steam or hot-water systems. It is rated for steam service in the 5 to 125 psi range and hot-water service up to about 150 psi, opening when energized to permit flow and sealing shut when de-energized. Typical configurations include 2-way, 2-position operation with NC (normally closed) behavior, making it a common choice for automated heating-system sequencing and process-control applications.
