Honeywell V5086A-1023 radiator valve with a 1/2 in NPT threaded connection is designed to regulate water flow in hydronic heating systems. This valve controls radiator temperature by modulating the water passing through the radiator circuit. The 1/2 inch NPT specification defines the connection size and threading for compatible installation in standard radiator piping. Part of Honeywell's V5086A family, this valve fits systems that use NPT-threaded radiator fittings.
