P29NC-38C Johnson Controls Pressure Control

Overview

The Johnson Controls VG7841GT+7152G is a high-performance valve and actuator assembly designed for hot water, chilled water, or steam control in commercial HVAC systems. It integrates a 1/2-inch three-way mixing globe valve from the VG7000 series with a VA-7152 series non-spring-return electric actuator, providing accurate and stable environmental control.

Features

• Three-way mixing design with a linear flow characteristic for reliable fluid proportioning.
• Cast bronze body with durable brass trim and a long-life replaceable ring packing for excellent reliability.
• VA-7152 series non-spring-return electric actuator delivers 90 lbs of force for a tight close-off.
• Features a direct-coupled setup requiring no complex external linkages.
• Equipped with a magnetic clutch to protect internal gearing and ensure consistent sealing.

Specifications

• Pipe Size: 1/2 inch
• Connection Type: NPT (Threaded FNPT)
• Flow Capacity: 4.6 Cv
• Maximum Static Pressure: 400 psi up to 150°F
• Power Supply: 24 VAC, 50/60 Hz, 4.7 VA
• Control Signal: Proportional / Analog (0-10 VDC, 0-5 VDC, or 5-10 VDC jumper selectable)
• Medium Temperature Range: 35°F to 284°F
• Pressure Class: Meets ASME B16.15 Class 250 requirements

Applications

• Designed for precise flow modulation in commercial heating, ventilation, and air conditioning (HVAC) applications.
