VG7441GT+3008EP Johnson Controls Valve / Actuator

Overview

The Johnson Controls VG7441GT+3008EP is a high-performance 1/2-inch 2-way globe valve assembly designed for the precise control of hot water, chilled water, and steam in commercial HVAC systems. Featuring a normally closed configuration (push-down-to-open), it utilizes a factory-mounted V-3000 pneumatic actuator with an exposed design and a positioner to ensure optimal, reliable valve positioning. The cast bronze body paired with brass trim provides excellent durability and equal percentage flow characteristics, delivering highly efficient performance for demanding building automation applications.

Features

• Heavy-duty cast bronze body with brass trim offers reliable corrosion protection and long-term durability.
• Factory-mounted V-3000 pneumatic actuator with positioner provides precise control over valve adjustments.
• Normally closed operation (push-down-to-open) ensures a reliable fail-safe position.
• Equal percentage flow characteristic provides precise and stable linear control across a 25:1 rangeability.
• Long operational lifetime, with the series tested to withstand over one million cycles.
• Serviceable design allows for in-place valve repacking to maximize uptime and lower maintenance costs.
