VG7441GT+423GGA Johnson Controls Valve / Actuator

Overview

The Johnson Controls VG7441GT+423GGA is an actuated valve assembly that combines a 1/2-inch 2-way globe valve from the VG7000 Series with a VA-4233-GGA-2 spring-return electric actuator. It features a durable cast bronze body with brass trim and is designed to provide precise, proportional control of hot water, chilled water, glycol solutions, or steam in commercial heating, ventilating, and air conditioning systems. The valve operates in a normally closed configuration, requiring a push-down-to-open action.

Features

• High-reliability long-life replaceable ring packing that provides excellent tight shut-off performance
• Cast bronze body with brass trim for robust corrosion protection
• Equal percentage flow characteristics for stable and precise control
• Equipped with a VA-4233-GGA-2 spring return electric actuator providing 61 lb-f torque
• Actuator features selector switches allowing field conversion between proportional, floating, or on/off control
• Includes a 12-foot cable for convenient electrical installation and connections
