Johnson Controls VG7241RT Valve

The Johnson Controls VG7241RT is a professional-grade 1-1/2 inch 2-way normally open globe valve engineered specifically for precise regulation of hot water, chilled water, or 38 psig saturated steam in commercial HVAC systems. This VG7000 Series valve features a rugged cast bronze body and a high-performance brass trim, ensuring structural integrity under high-demand conditions. With a 28.9 Cv rating and an equal percentage flow characteristic, it provides the throttling accuracy required for modern building automation sequences. The normally open configuration ensures that the valve remains at full flow in the event of an actuator signal loss, protecting systems from freezing or overheating depending on the application. Designed with a standard threaded stem and push-down-to-close action, it is fully compatible with a wide array of pneumatic and electric actuators, including the VA-7000 and VA-4233 series. This 1-1/2" NPT globe valve supports fluid temperatures ranging from 35°F to 284°F, making it a versatile choice for standard hydronic loops and low-pressure steam service.

• Optimized Flow Control: The equal percentage flow design provides superior control at the lower end of the stroke, preventing hunting in variable load systems.
• Durable Construction: Built with a cast bronze body and brass trim to withstand the corrosive environments typical of HVAC hydronic systems.
• Versatile Actuation: Features a standard threaded stem that integrates seamlessly with both electric and pneumatic VG7000 series actuators.
• Safety-First Design: Normally open (N.O.) fail-safe position ensures continued media flow during power or signal interruptions.
• Wide Temperature Range: Rated for fluids between 35°F and 284°F, covering common chilled water and saturated steam applications.

What is the maximum close-off pressure for the VG7241RT?
Close-off pressure is dependent on the specific actuator used; however, typical pneumatic configurations provide close-off ratings around 35-109 PSI depending on the spring range and supply air pressure.

Can this valve be used for steam applications?
Yes, the VG7241RT is rated for saturated steam up to 38 psig. For higher pressure steam requirements, a stainless steel trim model would be necessary.

What types of actuators can be mounted to this 1-1/2" valve?
It is designed for use with Johnson Controls VA-715x, VA-720x, and VA-4233 series electric actuators, as well as V-3000 and MP8000 series pneumatic actuators.
