VG7842NT+72CHGA Johnson Controls Valve / Actuator

Overview

The Johnson Controls VG7842NT+72CHGA is a 1-inch, 3-way mixing cast bronze globe valve assembly integrated with a VA7820 series spring-return electric actuator. It is engineered to precisely regulate fluid flow in response to the demand of an HVAC controller.

Features

• Equipped with a field-selectable spring-return electric actuator supporting proportional, on/off, or floating control.
• Features a durable cast bronze body with corrosion-resistant brass linear trim.
• Utilizes long-life replaceable ring packing for increased reliability and easy in-place serviceability.
• Every valve is factory-tested to ensure tight fluid shutoff.

Specifications

• Valve Size and Pattern: 1-inch, 3-way mixing with NPT threaded end connections.
• Flow Capacity: 11.6 Cv with linear flow characteristics and a 1/2-inch stroke.
• Pressure Ratings: ASME B16.15 Class 250 body rating with a closeoff pressure of 182/213 psig.
• Electrical and Force: 24 VAC supply voltage generating a 180 lb force.
• Fluid Limits: Water limits from 35 to 284 degrees Fahrenheit; saturated steam up to 38 psig at 284 degrees Fahrenheit.

Applications
