VG12A5GT Johnson Controls Ball Valve

Overview

The Johnson Controls VG12A5GT is a heavy-duty, 2-1/2 inch 2-way flanged ball valve designed to regulate the flow of hot water, chilled water, and 50/50 glycol solutions in commercial HVAC systems. It features a forged brass body with a 300 series stainless steel ball and stem assembly, delivering exceptional corrosion resistance and a maintenance-free design that performs for over 200,000 cycles. It comes less actuator, allowing for field mounting of compatible spring return or non-spring return electric actuators.

Features

• Heavy-duty forged brass body providing high static pressure integrity
• 300 Series stainless steel ball and stem for enhanced corrosion resistance and longevity
• Amodel flow characterizing disk providing an equal percentage flow characteristic for stable, accurate temperature control
• Graphite-reinforced PTFE seats backed with EPDM O-rings to maintain a constant seating force and prevent leaks
• Maintenance-free design tested for reliable performance in iron-oxide contaminated water
