Johnson Controls VG2231VM Valve

The Johnson Controls VG2231VM is a heavy-duty 4-inch globe valve engineered for precision control in high-capacity HVAC systems. This 2-way normally open valve features an ANSI Class 125 flat-faced flange connection and a robust cast iron body designed to handle rigorous commercial demands. With a 150 Cv flow coefficient and a modified linear flow characteristic, it ensures stable modulation in chilled or hot water applications. The internal assembly utilizes brass trim and a 3/8-inch threaded stem configured for push-down-to-close action. Technicians prefer this series for its reliable seating and compatibility with pneumatic or electric actuators. Whether managing primary loop flow or large-scale air handling units, this VG2000 series flanged valve provides the mechanical durability required for precise pressure and temperature regulation in complex hydronic circuits.

Key Benefits

• Optimized Flow Control: The 150 Cv rating and modified linear profile prevent hunting in the control loop.
• Industrial Construction: Rugged cast iron body with brass trim provides longevity in closed-loop hydronic systems.
• Standardized Fitment: ANSI Class 125 flanged ends ensure straightforward integration with existing 4-inch piping infrastructure.
• Field Serviceable: The push-down-to-close stem design allows for standard actuator mounting and easier maintenance access.

Common Questions

What is the maximum fluid temperature for the VG2231VM?
