Description
Overview
The Johnson Controls VG7281NT is a 2-way, normally open globe valve engineered for precise flow control in commercial HVAC hydronic systems. Featuring a 1″ union sweat connection with standard tubing, this valve is built for easy installation and reliable long-term performance. Its cast bronze body and brass trim construction deliver outstanding corrosion resistance and durability in demanding heating and cooling applications.
Flow Characteristics
The VG7281NT utilizes an equal percentage flow characteristic, which provides smooth, proportional control across the full stroke range. This makes it ideal for applications where precise modulation is critical, such as chilled water coils, hot water coils, and heat exchangers.
