Johnson Controls VG1241AD Valve

The Johnson Controls VG1241AD Valve is a high-performance 1/2 inch NPT ball valve engineered for the precise regulation of hot and chilled water or 50% glycol solutions in commercial HVAC systems. Featuring a 1.2 Cv flow coefficient, this two-way control valve utilizes an integrated Amodel flow characterization disk to deliver a consistent equal percentage flow characteristic, ensuring linear heat transfer and stable temperature control across the full range of operation. The forged brass body is rated for a static pressure of 580 psig, while the plated brass trim and blowout-proof stem provide field-proven reliability in demanding hydronic applications. Designed for seamless integration with Johnson Controls VA9104 or VA9203 series electric actuators, its 500:1 rangeability enables fine-tuned throttling that mitigates hunting in the control loop. With a high close-off pressure rating of 200 psi and dual EPDM O-ring stem seals, the VG1241AD maintains a leak-free seal beyond 200,000 cycles even in iron-oxide contaminated water, reducing long-term maintenance requirements for mechanical contractors.

• Precise Flow Control: The Amodel disk ensures equal percentage flow for optimized heat exchanger performance.
• Heavy-Duty Construction: Built with a forged brass body and plated brass trim to withstand up to 580 psig static pressure.
• Exceptional Seal Life: Dual EPDM O-ring seals and graphite-reinforced PTFE seats are tested for 200,000 cycles.
• Universal Compatibility: Standard 1/2" NPT connections and a compact profile allow for easy installation in tight mechanical spaces.
• High Close-Off: Rated for 200 psi close-off, ensuring tight shut-off and preventing ghost flows in the system.

What actuators are compatible with the VG1241AD?
This valve is designed to be field-mounted with Johnson Controls M9000 series actuators, specifically the VA9104 non-spring return and VA9203 spring return models for proportional or on/off control.

Can this valve be used for steam applications?
The VG1241AD features brass trim, which is rated for water and glycol. For low-pressure steam up to 15 psig, a stainless steel trim model from the VG1000 series is required.

What is the maximum fluid temperature rating?
This Johnson Controls VG1241AD handles a fluid temperature range of 23?F to 203?F (-5?C to 95?C), making it suitable for both chilled water and standard hydronic heating loops.
