Johnson Controls VG1841DP Valve

For contractors managing hydronic systems, the Johnson Controls VG1841DP Valve is a robust 1 1/4 inch 3-way solution engineered for precision and long-term reliability. This VG1000 Series ball valve features a forged brass body and plated brass trim, specifically designed to regulate the flow of hot or chilled water and 50% glycol solutions. With a high Cv rating of 18.7, it utilizes a characterized Amodel flow disk to ensure an equal percentage flow characteristic, providing stable temperature control and superior rangeability even in variable load conditions. The NPT threaded connection allows for straightforward integration into existing piping, while the maintenance-free design is rated for 200,000 leak-free cycles in iron-oxide contaminated water. Using dual EPDM o-ring stem seals and 15% graphite-reinforced PTFE seats, the VG1841DP offers a sustainable close-off pressure of 200 psi, making it an essential component for demanding HVAC control valve applications where performance is non-negotiable.

• Accurate Flow Control: The built-in Amodel flow characterizing disk ensures an equal percentage flow, preventing hunting and providing stable control for fan coils and air handlers.
• Durable Construction: Built with a forged brass body and blowout-proof stem to handle static pressures up to 580 psig.
• Low Operating Torque: Graphite-reinforced PTFE seats provide consistent seating force and reduced friction, allowing for the use of smaller, more cost-effective actuators.
• System Compatibility: Designed for seamless field or factory mounting with VA9104, VA9203, and VA9300 series electric actuators.

What is the maximum fluid temperature for this valve?
The brass trim configuration on the VG1841DP is rated for fluid temperatures ranging from 23°F to 203°F.

Can this valve be used for steam applications?
No, this specific model with brass trim is intended for water and glycol. For low-pressure steam up to 15 psi, a stainless steel trim VG1000 series model is required.

What is the close-off pressure rating?
This 3-way valve provides a tight close-off rating of 200 psi, ensuring minimal leakage and reliable shut-off in commercial hydronic circuits.
