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. Key Benefits 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. Common Questions 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.
