VG7842NT+7150G Johnson Controls Valve / Actuator

Overview

The Johnson Controls VG7842NT+7150G is a high-performance 1-inch 3-way mixing globe valve assembly integrated with a VA-7150 series non-spring return electric actuator. Designed for commercial and residential HVAC systems, this assembly provides precise temperature and fluid flow control of hot water, chilled water, or steam. It features a robust cast bronze body with a flow coefficient of 11.6 Cv and utilizes a synchronous motor-driven actuator to deliver dependable, energy-efficient operation in complex climate control environments.

Features

• Synchronous motor-driven VA-7150 electric actuator delivers 90 lb (500 N) of nominal thrust in a compact design.
• Built-in magnetic clutch provides a constant output force for positive close-off while protecting the motor from damage during stall conditions.
• Unique yoke design allows for easy field mounting and reduced stroke adjustment time.
• Standard 3-way linear flow characteristic optimizes fluid mixing applications.
• Robust construction utilizing a durable cast bronze body and a stainless steel stem to ensure a long operational cycle life.
