VG72K1PT Johnson Controls Recondition Kit

Overview

The Johnson Controls VG7241GT+423GGA is a high-performance valve and actuator assembly combining a 1/2-inch 2-way cast bronze globe valve with a VA-4233-GGA-2 spring-return electric actuator. It features an equal percentage flow characteristic with a Cv of 4.6, brass trim, and operates as normally open (push-down-to-close). This assembly provides precise proportional control for water and steam systems in commercial building automation and HVAC environments.
