Johnson Controls VG1241BN Ball Valve

The Johnson Controls VG1241BN Ball Valve is a 3/4-inch NPT two-way control valve engineered for precision regulation in closed-loop HVAC systems. Built with a forged brass body and brass trim, this unit offers a static pressure rating of 580 psig and features an 11.7 Cv flow coefficient. Designed specifically for chilled and hot water applications, it utilizes a graphite-reinforced PTFE seat to ensure a leak-free seal across a fluid temperature range of 23°F to 203°F. The equal percentage flow characteristic provided by the characterizing disk ensures linear heat output, optimizing energy efficiency and system stability. This VG1000 Series ball valve is compatible with the VA9104, VA9203, and VA9300 series actuator assemblies for proportional or on/off control. With a 200 psi closeoff pressure and 500:1 rangeability, it provides the robust shutoff and fine-tuned modulation required for demanding commercial hydronic systems.

Key Benefits

• Optimized Flow Control: Featuring an 11.7 Cv rating and equal percentage flow for precise modulation of hydronic loads.
• Industrial-Grade Durability: The forged brass body and chrome-plated brass trim provide a static pressure rating of 580 psig.
• Maintenance-Free Reliability: Tested to exceed 200,000 cycles, with graphite-reinforced PTFE seats and EPDM O-rings for long-term leakage protection.
• High Closeoff Capability: Reliably manages up to 200 psi closeoff pressure, preventing unintended flow and system drifting.

Common Questions

Is the VG1241BN suitable for steam service?
No, this specific model features brass trim and is rated only for hot and chilled water applications. For low-pressure steam service up to 15 psig, a stainless steel trim model from the VG1000 series is required.

Which actuators are compatible with this valve body?
The valve is designed to interface with Johnson Controls direct-coupled actuators, including the VA9104 and VA9300 Non-Spring Return series, as well as the VA9203 and VA9208 Spring-Return series.

Can this valve be used in potable water systems?
This valve is intended for HVAC hydronic systems only and does not meet the low-lead requirements for potable water applications.
