Johnson Controls VG1841AE Valve

The Johnson Controls VG1841AE Valve is a high-performance 1/2-inch 3-way ball valve engineered for demanding HVACR systems. Built with a forged brass body and plated brass trim, this unit is designed to regulate the flow of hot or chilled water in response to specific controller demands. Featuring an equal percentage flow characteristic via a specialized internal disk, it ensures linear heat transfer in coils for precise temperature management. The 1.9 Cv rating is tailored for low-flow applications requiring a 200 psi close-off pressure to prevent bypass leakage. This NPT threaded valve is fully compatible with Johnson Controls M9000 and VA9000 series actuators, providing seamless integration for proportional, floating, or on/off control. With graphite-reinforced PTFE seats and EPDM O-rings, the assembly is rated for a broad fluid temperature range from 23?F to 203?F, maintaining 580 psig static pressure integrity in complex hydronic circuits.

• Precise Flow Control: The equal percentage flow characteristic provides stable control at lower openings, preventing hunting and system instability.
• High Close-Off Rating: Delivers 200 psi close-off pressure to ensure tight shutoff and prevent unintended energy transfer through the bypass.
• Rugged Forged Construction: The forged brass body and nickel-plated stem offer superior durability and 200,000-cycle life expectancy.
• Actuator Compatibility: Designed for field or factory mounting with VA9104, M9106, and VA9203 series electric actuators.

What is the proper piping configuration for this 3-way valve?
For mixing applications, Port A must be the coil inlet and Port B the bypass inlet. Ensure the actuator is mounted at or above the pipe centerline to prevent moisture damage.

Can this brass trim model be used for steam service?
No, the VG1841AE with brass trim is rated for hot and chilled water only. Stainless steel trim models are required for low-pressure steam applications.

What maintenance is required for the VG1000 series?
This is a maintenance-free design. If the valve fails to operate within its original technical specifications, the assembly or valve body should be replaced.
