Johnson Controls VG1845BN 3/4" Three-Way Forged Brass Ball Valve with Stainless Steel Trim, 11.7 Cv NPT

The Johnson Controls VG1845BN is a 3/4-inch, three-way forged brass ball valve with stainless steel trim, part of the VG1000 Series designed for precise flow control in commercial and industrial HVAC systems. With an 11.7 Cv flow coefficient and female NPT (FNPT) threaded end connections, this valve delivers the flow capacity of a traditional globe valve in a compact, reliable ball valve design.

Engineered to regulate the flow of hot water, chilled water, 50% glycol solutions, and low-pressure steam (up to 15 psig with thermal spacer), the VG1845BN is built for demanding hydronic applications. Its forged brass body provides exceptional durability, while the stainless steel ball and blowout-proof stem ensure long service life and safe operation under pressure.

Key Features:

• 3/4" three-way valve body with 11.7 Cv flow coefficient
• Forged brass body construction with stainless steel ball and blowout-proof stem
• Female NPT (FNPT) threaded end connections
• 200 psig closeoff pressure rating; 580 psig static pressure rating
• Maximum water temperature: 284°F; Steam rated to 15 psig (with thermal spacer)
• Characterized insert provides equal percentage flow control
• Direct-mount design compatible with Johnson Controls M9000 and VA9000 Series electric actuators
• Supports on/off, floating, and proportional control when paired with compatible actuators
• Valve only — actuator sold separately

The VG1845BN is a valve-only unit designed for factory or field mounting with Johnson Controls VA9104, M9106, M9109, and M9100 Series Non-Spring-Return, and VA9203 and VA9208 Series Spring-Return electric actuators. Its equal percentage flow characteristic and broad Cv range make it an ideal choice for accurate hydronic balancing and zone control in commercial HVAC installations.
