VG1245AD+9T4GGA Johnson Controls Valve / Actuator

Overview

The Johnson Controls VG1245AD+9T4GGA is an actuated ball valve assembly that combines a 1/2-inch, 2-way forged brass ball valve with a VA9104-GGA-3S non-spring return electric actuator. Designed to regulate the flow of hot water, chilled water, glycol solutions, and low-pressure steam, this assembly delivers highly precise and accurate control in response to the demands of a controller. It features an innovative flow characterizing disk to maintain optimal temperature regulation and utilizes a durable stainless steel ball and stem for reliable long-term performance.

Features

• High-Performance Construction: Built with a forged brass body, 300 series stainless steel ball and stem, EPDM O-ring stem seals, and graphite-reinforced PTFE seats.
• Equal Percentage Flow: Equipt with a flow characterizing disk to maintain equal percentage flow characteristics, providing superior temperature control.
• High Life Expectancy: Tested to provide a minimum of 200,000 leak-free, full-cycle operations.
• Direct-Coupled Actuator: Comes factory-assembled with a VA9104 non-spring return electric actuator featuring M3 screw terminals for quick electrical connection.
