VG7842RT+7152G Johnson Controls Valve / Actuator

Overview

The Johnson Controls VG7842RT+7152G is a high-performance 1-1/2 inch 3-way mixing globe valve assembly integrated with a VA-7152 series non-spring-return electric actuator. It features a rugged cast bronze body designed to regulate hot water, chilled water, or glycol solutions up to 50% concentration in commercial HVAC building automation systems. Driven by a 24 VAC proportional electric motor actuator, it delivers reliable, precise flow control and exceptional rangeability.

Features

• Direct-coupled non-spring-return electric actuator simplifies installation by removing the need for external linkages.
• Magnetic clutch technology ensures tight shutoff protection and safeguards internal gearing from damage.
• Long-lasting replaceable ring packing ensures maximum system reliability and service longevity.
• Rated for up to one million operating cycles to minimize required maintenance.
