Product Details

The Johnson Controls VG1845BNH943BUA is a factory-assembled 3/4-inch, 3-way forged brass ball valve and electric actuator assembly designed for precise flow regulation of hot water, chilled water, and low-pressure steam in commercial HVAC systems. With a flow coefficient (Cv) of 11.7, this assembly delivers reliable, repeatable performance across a wide range of hydronic applications.

The VG1845 series valve body features a forged brass construction with stainless steel ball and blowout-proof stem, rated for up to 580 psig static pressure. The 3-way configuration enables diverting or mixing of fluid streams, making it ideal for terminal unit control, fan coil units, and air handling unit coil circuits. NPT end connections simplify field installation and reduce the need for additional adapters.

The integrated 943BUA electric actuator operates on a broad 85–264V universal voltage input, eliminating the need to specify line voltage at time of order — compatible with both 120V and 240V applications. The actuator provides 2-position (on/off) control with a Normally Closed (NC) fail-safe position, ensuring the valve returns to the closed state upon loss of power.

Key Features:

  • 3/4-inch NPT end connections for straightforward pipe installation
  • 3-way ball valve configuration for diverting or mixing applications
  • 11.7 Cv flow coefficient for optimized flow capacity
  • Forged brass valve body rated to 580 psig static pressure
  • Stainless steel ball and blowout-proof stem for long service life
  • 500:1 rangeability for accurate control under all load conditions
  • 85–264V universal voltage input — compatible with 120V and 240V systems
  • 2-position (on/off) control with Normally Closed fail-safe
  • Factory-mounted actuator for reduced installation time
  • Graphite-reinforced PTFE seats for superior wear resistance
  • Maintenance-free design rated for 200,000+ full-stroke cycles

The VG1845BNH943BUA is part of the Johnson Controls VG1000 Series, a trusted platform in commercial building automation. This assembly is compatible with Johnson Controls building automation systems (BAS) and is suitable for use in plenum-rated environments.

Great product - The Escape hatch cover I purchased was new and was in perfect condition when it arrived. Shipping was fast. I am very pleased.

I received my order of Shurflo replacement o-rings very quickly - sooner than expected. Unfortunately, I really only needed 1 or 2 o-rings, but they are only offered in a pack of 10. I'll never use 10 o-rings, so it was wasteful spending. I shopped other companies, and could not find packs of 1 or 2, and Boatplicity was the least expensive for what is available on-line.

Fast and convenient delivery, great price

I received my order today

Had the tires I wanted at a fair price and delivered quickly! Thank you!

Quick and easy. I can't tell if the tire is New or how much gas life is on it of the tire is used. Pictures make it look like the tire does not have much, if any, wear.
