Johnson Controls VG12A5HW Valve

The Johnson Controls VG12A5HW is a high-performance 3-inch flanged ball valve designed for precise flow control in demanding HVACR applications. Engineered with an ASME Class 150 flange connection, this 2-way ball valve features a 211 Cv rating and an equal percentage flow characteristic, ensuring stable modulation and hunting prevention in chilled or hot water systems. The rugged forged brass body is paired with stainless steel trim and a stainless steel ball, providing superior resistance to corrosion and scaling compared to standard chrome-plated components. This VG1000 series valve is built to handle high-pressure drops and maintains a bubble-tight shutoff to prevent energy loss. For contractors, the blowout-proof stem and high-temperature packing ensure long-term reliability in utility plant environments. Compatible with VA9000 series electric actuators, the VG12A5HW provides a low-torque solution for modern building automation systems seeking maximum efficiency and accurate temperature regulation.

Key Performance Benefits

• Precise Flow Control: The equal percentage flow curve provides linear heat output for optimized coil performance.
• Durable Construction: Stainless steel trim and ball offer enhanced protection against abrasive debris and chemical treatments.
• High Flow Capacity: A 211 Cv rating ensures minimal pressure drop across the valve in 3" piping systems.
• Standardized Integration: The ASME Class 150 flange ensures seamless installation into commercial piping networks.
• Zero Leakage: Internal seals provide a bubble-tight shutoff at high differential pressures.

Common Installation Questions

Is the VG12A5HW compatible with steam applications?
No, this specific forged brass valve is engineered primarily for chilled and hot water applications. Always verify the fluid medium and temperature ratings against the technical datasheet before installation.

What actuators are compatible with this 3-inch flanged valve?
The valve is designed to interface with Johnson Controls VA9104, VA9208, or VA9300 series actuators depending on the torque and control signal requirements of your BAS.

Can this valve be mounted in any orientation?
For optimal longevity, it is recommended to mount the valve with the actuator in the upright or horizontal position to prevent moisture from entering the drive mechanism.
