Johnson Controls VG7241LT+3003D Valve Assembly

The Johnson Controls VG7241LT+3003D is a rugged, field-proven 2-way normally open pneumatic globe valve assembly engineered for precise modulating control in commercial HVAC systems. This 3/4-inch NPT valve features a high-grade cast bronze body and durable brass trim, ensuring reliable performance when handling hot water, chilled water, or 50/50 glycol solutions. With a 7.3 Cv rating and an equal percentage flow characteristic, it provides stable fluid regulation even under varying pressure drops. The assembly is equipped with a V-3000 series enclosed pneumatic actuator featuring a 4-8 PSI spring range, allowing for efficient spring return operation. This VG7000 series assembly is designed to meet ANSI Class 250 standards, making it a staple for contractors maintaining pneumatic terminal unit control and air handling systems. Its compact yoke design facilitates installation in tight mechanical spaces while maintaining serviceability for long-term facility maintenance.

Key Benefits

• Optimized Flow Control: The 7.3 Cv equal percentage flow design prevents hunting and ensures stable temperature regulation in mixing or throttling applications.
• Durable Construction: Built with a cast bronze body and brass trim to withstand the rigors of continuous HVAC cycling and resist internal corrosion.
• Reliable Failsafe: The spring return enclosed pneumatic actuator ensures the valve returns to its normally open position during a loss of control air.
• High Pressure Rating: Complies with ANSI Class 250, providing the structural integrity needed for high-static pressure hydronic loops.
• Industry Standard Compatibility: Native 3/4" NPT connections and a 4-8 PSI spring range allow for seamless integration into existing Johnson Controls pneumatic systems.

Common Questions

What media is the VG7241LT+3003D compatible with?
This valve is designed for use with hot water, chilled water, and glycol solutions up to 50% concentration. It is also rated for saturated steam applications up to 38 psig.

Can the actuator be replaced without removing the valve from the line?
Yes, the VG7000 series features a modular design that allows for the pneumatic actuator to be serviced or replaced while the bronze valve body remains in the piping.

What is the default position of this assembly?
This specific configuration is normally open (N.O.), meaning the valve remains in the open position via the internal spring until pneumatic pressure is applied to the 3003D actuator.
