PAN-ENH1620WDP Johnson Controls PANEL

Overview

The Johnson Controls VG7842ET+7150G is a 1/2-inch 3-way mixing globe valve assembly equipped with a VA-7150 series non-spring-return electric actuator. Designed for commercial HVAC systems, this assembly precisely regulates fluid temperatures by blending hot and cold water or steam in hydronic loops to achieve specific control setpoints. It features a durable cast bronze body with brass trim, offering high reliability and excellent corrosion resistance.

Features

• Three-way mixing configuration optimizes temperature consistency by smoothly blending fluid paths.
• VA-7150 non-spring-return electric actuator provides direct-coupled installation with no additional linkage required.
• Magnetic clutch protects internal gearing and ensures a tight close-off with 90 lbs of force.
• Long service life with over one million cycles tested for sustained operational durability.
• Serviceable design permits in-place valve repacking to reduce maintenance downtime.
