VG7443GT Johnson Controls Valve

Overview

The Johnson Controls VG7443GT is a high-performance 2-way bronze globe valve designed to regulate the flow of hot water, chilled water, or steam in commercial heating, ventilating, and air conditioning (HVAC) systems. Belonging to the VG7000 Series, this valve operates with a Push-Down-to-Open (PDTO) action, meaning it is normally closed when using pneumatic or spring return actuators. It features durable stainless steel trim for extended operating life and utilizes standard Johnson Controls Ring Pack Packings to ensure maximum reliability and tightly sealed shutoff.

Features

• Push-Down-to-Open (PDTO) configuration, functioning as a Normally Closed valve.
• High-durability stainless steel trim designed to withstand demanding environments, including saturated steam.
• Standard Johnson Controls Ring Pack Packings provide industry-leading reliability and extended operating life.
• Every individual valve is strictly tested for tight shutoff to ensure optimal occupant comfort and maximize energy conservation.
• Standardized bonnet and stem design allows complete actuator interchangeability for seamless field retrofits or upgrades.
• ANSI Class 250 pressure/temperature compliance guarantees safety standards and robust operational limits.
