Johnson Controls VG7241NT Valve

The Johnson Controls VG7241NT is a high-performance 1 inch NPT globe valve engineered for precise modulation in commercial HVAC systems. This 2-way normally open valve features a cast bronze body and brass trim, providing a robust solution for regulating hot water, chilled water, and saturated steam up to 38 psig. With a 11.6 Cv rating and an equal percentage flow characteristic, it ensures stable and linear thermal output across varying load conditions. Designed with a standard threaded stem and push-down-to-close operation, this valve is fully compatible with VA-7000 and VA-4233 series electric actuators, as well as V-3000 pneumatic series. The ANSI Class 250 pressure rating and spring-loaded V-ring packing offer long-term reliability and leak-free performance in demanding mechanical rooms. Contractors selecting this VG7000 series component can rely on its industry-standard dimensions for seamless field retrofits and efficient system integration.

• Equal percentage flow characteristic provides superior modulation and precise control of heat exchangers and coils.
• Cast bronze construction with brass trim ensures high durability and resistance to corrosion in hydronic applications.
• Normally open fail-safe position (Push-Down-to-Close) maintains flow during power or signal loss.
• Actuator interchangeability allows for easy mounting of both pneumatic and electric actuators using standardized kits.
• ANSI Class 250 rating supports high-pressure system requirements with a temperature range of 35°F to 284°F.

What is the maximum close-off pressure for the VG7241NT?
The close-off pressure depends on the specific actuator paired with the valve. For instance, pairing with a VA-4233 series actuator typically provides a 63 psig close-off rating.

Can this valve be used for steam applications?
Yes, the VG7241NT is rated for saturated steam up to 38 psig when used with appropriate high-temperature packing and compatible actuators.

Is the packing field-serviceable?
The VG7000 series is designed for longevity, featuring standard ring packings that allow for in-place valve repacking to minimize system downtime.
