Johnson Controls VG1241ES Valve

The Johnson Controls VG1241ES is a heavy-duty 1 1/2" 2-way ball valve specifically engineered for precise control in commercial HVACR hydronic systems. This forged brass ball valve features a 46.8 Cv rating and is designed with a characterized insert to provide an equal percentage flow characteristic, ensuring linear heat output across a wide range of actuator strokes. Built with a chrome-plated brass ball and a nickel-plated brass stem, the VG1241ES is optimized for chilled water, hot water, and 50% glycol solutions. Its robust NPT threaded connections and EPDM O-ring stem seals support a static pressure rating of up to 580 psig, making it a reliable choice for high-demand HVAC control valve applications. The VG1000 series architecture allows for seamless field-mounting of spring return or non-spring return electric actuators, providing technicians with the flexibility required for complex site retrofits or new installations without compromising on long-term seal integrity or flow accuracy.

• Equal Percentage Flow: Provides predictable control and stable temperature regulation even under varying load conditions.
• High Flow Capacity: The 46.8 Cv rating ensures low pressure drop across the 1 1/2" NPT piping for 1.8 million parts in stock efficiency.
• Durable Construction: Forged brass body and graphite-reinforced PTFE seats offer exceptional wear resistance in iron-oxide contaminated systems.
• Maintenance-Free Reliability: Tested for over 200,000 leak-free cycles to ensure uptime in critical mechanical rooms.
• Versatile Media Handling: Compatible with fluids ranging from 23?F to 203?F, covering most standard heating and cooling specifications.

Is the VG1241ES rated for steam service?
No, this specific model with brass trim is rated for hot and chilled water and glycol only. For saturated steam applications up to 15 psig, a stainless steel trim model from the VG1000 series is required.

What actuators are compatible with this valve body?
The VG1241ES is designed to work with Johnson Controls VA9104, M9109, VA9203, and VA9208 series actuators. Ensure the correct mounting linkage is used for non-integral models.

Can this valve be installed in any orientation?
The valve should be installed with the actuator at or above the centerline of horizontal piping. Do not mount the actuator below the pipe to prevent damage from condensation or leakage.
