Johnson Controls VG1241AG Valve

The Johnson Controls VG1241AG is a high-performance 1/2 inch NPT ball valve engineered specifically for precise control in hot and chilled water systems. This two-way control valve features a 4.7 Cv rating and an equal percentage flow characteristic, provided by a specialized Amodel flow-characterizing disk. The forged brass body is complemented by plated brass trim, ensuring reliable operation across a wide fluid temperature range of 23?F to 203?F. Designed for HVACR contractors, this valve supports a 580 psig static pressure rating and can handle close-off pressures up to 200 psi. The VG1000 Series ball valve is highly compatible with VA9104, M9106, and M9109 series non-spring return actuators, as well as VA9203 and VA9208 spring return models. With a maintenance-free design featuring dual EPDM stem seals and 15% graphite-filled PTFE seats, it is rated for a 200,000-cycle life expectancy in non-potable water and 50% glycol applications.

Key Benefits

• Precise Flow Control: The equal percentage flow disk ensures stable control loop performance, matching the heat transfer characteristics of HVAC coils.
• High Pressure Capability: Rated for 580 psig static pressure and 200 psi close-off, minimizing the risk of blow-by in high-head systems.
• Durable Construction: Forged brass body with dual EPDM stem seals provides a leak-free seal tested for over 200,000 cycles.
• Flexible Actuation: Universal mounting for Johnson Controls actuators, allowing for seamless field or factory assembly.

Common Questions What media is the VG1241AG compatible with? It is designed for hot water, chilled water, and up to 50% glycol solutions. Note that brass trim models are typically not rated for steam service; for low-pressure steam, stainless steel trim models are recommended. Can this valve be used for potable water? No, this part is intended for non-potable HVACR applications and does not meet the low-lead requirements for drinking water systems. Is the internal flow disk orientation specific? Yes, the flow-characterizing disk is located in Port A. For proper operation, Port A must be designated as the inlet to maintain the equal percentage flow characteristic.
