Johnson Controls VG1241BG Valve

The Johnson Controls VG1241BG is a 3/4-inch, two-way NPT forged brass ball valve engineered for precise fluid control in commercial HVACR systems. With a 4.7 Cv rating and a 500:1 rangeability, this valve utilizes an Amodel flow characterizing disk to maintain equal percentage flow characteristics, ensuring stable temperature regulation in chilled water, hot water, and up to 50/50 glycol solutions. This model features a chrome-plated brass ball and stem assembly, providing a cost-effective solution for standard hydronic applications. Designed for maximum durability, the valve is rated for 580 psig static pressure and 200 psid close-off pressure, effectively preventing leakage and system instability. The maintenance-free design is tested to exceed 200,000 full-stroke cycles, even in iron-oxide contaminated water, thanks to its graphite-reinforced PTFE seats and EPDM double O-ring stem seals. This HVAC control valve is compatible with VA9104, VA9203, and VA9208 series actuators, making it a versatile choice for field-mounted or factory-actuated assemblies.

• Precise Modulation: The 500:1 rangeability and integrated flow disk provide superior control over low-load conditions compared to standard globe valves.
• High Pressure Rating: Rated for a 580 psig static pressure (PN40), ensuring integrity in high-rise and large-scale commercial piping.
• Debris Resistance: Graphite-reinforced PTFE seats offer enhanced wear resistance against pipe scale and iron oxide.
• Standard Connection: 3/4" FNPT threaded ends allow for straightforward integration into existing American standard piping systems.
• Reliable Shut-off: Achieves tight seal performance with a 200 psi close-off rating, minimizing energy loss from bypass leakage.

Is the VG1241BG suitable for steam service?
No, this specific model features brass trim (chrome-plated brass ball and stem) and is not rated for steam. For low-pressure steam applications up to 15 psig, you must select the stainless steel trim equivalent (VG1245 series).

Which actuators are compatible with this 3/4" valve?
This valve is designed for direct-couple mounting with Johnson Controls M9100, VA9104, and VA9200 series electric actuators. It supports on/off, floating, and proportional control depending on the selected actuator.

What are the fluid temperature limits?
The brass trim VG1241BG is rated for fluid temperatures ranging from 23?F to 203?F (-5?C to 95?C), making it ideal for standard chilled and hot water loops.
