Johnson Controls VG1841AL Valve

The Johnson Controls VG1841AL is a high-performance 3-way ball valve engineered for precise control of hot and chilled water in demanding HVAC systems. Featuring a 1/2 inch NPT threaded connection and a 7.4 Cv flow coefficient, this valve utilizes a forged brass body and plated brass trim for superior durability and corrosion resistance. The integrated Amodel flow characterizing disk ensures an equal percentage flow characteristic, delivering stable temperature control even in systems with high pressure fluctuations. Designed with a 500:1 rangeability and a 200 psi close-off rating, the VG1841AL provides the reliable performance professional contractors require for consistent mixing or diverting applications. The VG1000 Series architecture supports a variety of non-spring return and spring return actuators, making it a versatile choice for field or factory mounting.

• Equal Percentage Flow Control: The built-in flow characterizing disk optimizes valve response for precise thermal regulation.
• High Durability Construction: Features a forged brass body and graphite-reinforced PTFE seats, providing a cycle life exceeding 200,000 operations.
• Service Versatility: Suitable for chilled and hot water applications with a temperature range of 23?F to 203?F.
• Reliable Shut-off: Achieves tight seal performance with a 200 psi close-off pressure rating to prevent system bypass.
• Ease of Installation: Standard NPT threaded connections and a blowout-proof stem simplify integration into existing hydronic loops.

Is the VG1841AL suitable for steam applications?
No, this model features plated brass trim and is rated for hot and chilled water or glycol solutions up to 50%. For low-pressure steam, a stainless steel trim model must be specified.

Which actuators are compatible with this valve body?
It is designed to interface with Johnson Controls M9000 and VA9000 series actuators, including the VA9104, M9106, and VA9203 series for spring or non-spring return operation.

Does this valve require maintenance?
The VG1841AL is a maintenance-free design; there are no packing adjustments required over its operational lifespan due to the dual EPDM O-ring stem seals.
