VG1245AG+9A4GGA Johnson Controls Valve W/ Actuator

Overview

The Johnson Controls VG1245AG+9A4GGA is a factory-assembled 1/2-inch 2-way ball valve and electric actuator combination designed to regulate the flow of hot water, chilled water, or low-pressure steam in commercial HVAC systems. This assembly features a durable forged brass valve body with stainless steel trim and is paired with a VA9104-GGA-2S non-spring-return electric actuator for precise proportional control.
