Johnson Controls VG1845AN 1/2" Three-Way Forged Brass Ball Valve 11.7 Cv NPT

The Johnson Controls VG1845AN is a 1/2-inch, three-way forged brass ball valve from the VG1000 Series, designed for precise flow control in commercial HVAC hydronic systems. With a Cv rating of 11.7 and NPT end connections, this valve delivers reliable performance for hot water, chilled water, and glycol solution applications.

Part of Johnson Controls' VG1845 Series, this valve body is designed for factory or field mounting with compatible VA9104, M9106, M9109, and M9100 Series Non-Spring Return or VA9203 and VA9208 Series Spring Return electric actuators, enabling on/off, floating, or proportional control.

Key Features:

• Three-way valve body with equal percentage flow characteristic on the in-line port (coil) and linear flow characteristic on the angle port (bypass)
• Forged brass body rated to 580 psig (PN40) for durability and long service life
• Stainless steel ball and blowout-proof stem for safe, corrosion-resistant operation across a wide fluid temperature range of 23°F to 250°F (-5°C to 121°C)
• Graphite-reinforced PTFE seats with 15% graphite-reinforced ball seals for improved wear resistance
• EPDM O-ring stem seals tested leak-free after 200,000 cycles in iron-oxide contaminated water
• 200 psid maximum close-off pressure for tight shutoff performance
• 50 psid maximum recommended pressure drop with 500:1 rangeability for accurate control under all load conditions
• ANSI/FCI 70-2 Class IV leakage rating — 0.01% of maximum flow
• Compatible with hot or chilled water, up to 50% glycol solutions, and 15 psig saturated steam (stainless trim models)
• 1/2 in. NPT end connections; available for direct actuator mounting without additional linkage

The VG1845AN is a bare valve body intended for assembly with a compatible Johnson Controls electric actuator. Its compact design and high-flow Cv make it an ideal drop-in replacement or new-installation solution for zone control in commercial hydronic heating and cooling systems.
