P170LB-6C Johnson Controls Pressure Control

Overview

The Johnson Controls VG7441ET+423GGA is an actuated globe valve assembly designed primarily to regulate the flow of water and steam in response to the demand of a controller in HVAC systems. It combines a 1/2-inch 2-way normally closed mixing valve body with a VA-4233-GGA-2 spring-return electric actuator. The valve features a durable cast bronze body with brass trim and NPT threaded connections, providing reliable and precise control for commercial building environments.

Features

• Push-down-to-open, normally closed configuration with spring return stem up action.
• Equipped with a long-life replaceable ring packing that provides high reliability and maximum service life.
• Every valve unit is factory-tested for tight shut-off capabilities.
• Proportional control operates on a 0 to 10 VDC input signal.
• Manual opener functionality allows for easier setup and troubleshooting.
