Johnson Controls VG1241DR Valve

The Johnson Controls VG1241DR Valve is a high-performance 1 1/4-inch NPT ball valve engineered for precise control in HVACR systems. Featuring a 29.2 Cv rating, this two-way control valve is built with a forged brass body and plated brass trim, making it a reliable choice for regulating hot or chilled water and 50% glycol solutions. The equal percentage flow characteristic, provided by a specialized characterized insert, ensures optimal heat transfer and stable loop control by matching the non-linear response of heat exchangers. Field contractors rely on this VG1000 series valve for its 200,000-cycle life expectancy and the flexibility of NPT threaded connections for quick integration into existing pipe runs.

• Precise Modulation: The equal percentage flow design provides linear heat output for superior temperature stability in commercial hydronic systems.
• Robust Construction: Forged brass body combined with a chrome-plated brass ball and nickel-plated stem ensures long-term durability in non-potable applications.
• High Close-Off Pressure: Rated for up to 200 psid close-off, preventing leakage and unintended flow during system downtime.
• Versatile Application: Ideal for fan coil units, unit ventilators, and reheating coils within a wide media temperature range of 23? to 203?F.

What actuators are compatible with the VG1241DR?
This valve is designed for use with Johnson Controls VA9104 non-spring return or VA9203 and VA9208 spring return actuators using the appropriate linkage assemblies.

Can this valve be used for low-pressure steam?
No, this specific model features brass trim. For saturated steam applications up to 15 psig, a stainless steel trim model from the VG1000 series is required.

Does it matter which way the valve is installed?
Yes, for valves with a flow-characterizing disk (typically in Port A), Port A must serve as the inlet to ensure the intended equal percentage flow performance.
