Johnson Controls VG1241AL Ball Valve

As a veteran tech, you know the value of a dependable control surface in a hydronic loop. The Johnson Controls VG1241AL is a high-performance 1/2-inch NPT ball valve designed specifically for the demanding environment of commercial HVAC systems. This two-way control valve features a forged brass body and plated brass trim, providing a robust 580 psig static pressure rating that stands up to system surges. With a 7.4 Cv rating and a characterizing disk, this valve delivers an equal percentage flow characteristic, ensuring precise modulation even at low-load conditions. The graphite-reinforced PTFE seats and EPDM O-rings are engineered for longevity, capable of handling hot water, chilled water, and 50% glycol solutions across a temperature range of 23?F to 203?F. Optimized for Johnson Controls VG1000 Series actuators, it offers easy field mounting and a 200,000-cycle life expectancy, making it a reliable choice for HVAC zone control and terminal unit applications.

• Precise Flow Control: The integrated flow-characterizing disk transforms the standard ball valve into a precision instrument with an equal percentage flow curve.
• High Close-Off Pressure: Engineered to provide a 200-psid close-off rating, preventing leakage and ghost energy consumption in hydronic systems.
• Reduced Maintenance: Dual EPDM O-ring stem seals and blowout-proof stem design ensure a leak-free operation for over 200,000 cycles.
• Versatile Media Compatibility: Rated for water and up to 50% glycol mixtures, covering the vast majority of chilled and hot water applications.
• Compact Profile: The 1/2" NPT threaded connection and streamlined body geometry allow for installation in tight mechanical closets and terminal units.

What actuators are compatible with the VG1241AL?
This valve body is designed for direct-coupled Johnson Controls actuators, including the VA9104 non-spring return and the VA9203 or VA9208 spring-return series.

Can this valve be used for steam applications?
No. While some VG1000 models with stainless steel trim support low-pressure steam, the VG1241AL uses plated brass trim and is strictly for hot water, chilled water, and glycol solutions.

Which port should be used as the inlet?
For proper operation of the characterizing disk, ensure that Port A is positioned as the inlet. Correct orientation is critical for achieving the specified 7.4 Cv flow rate and control accuracy.
