The Johnson Controls VG1245BL is a heavy-duty 3/4 inch NPT ball valve engineered for precise hydronic control in commercial HVAC systems. Featuring a 7.4 Cv flow coefficient and a two-way equal percentage flow characteristic, this valve ensures linear control of hot or chilled water, as well as 50% glycol solutions. The forged brass body is complemented by 300 series stainless steel trim, specifically the ball and stem, which provides superior resistance to corrosion and scaling compared to standard brass components. Designed for use with VA9104, VA9203, and VA9208 actuators, this VG1000 series valve utilizes a blow-out proof stem and a double O-ring seal to prevent leaks under high-pressure conditions. Contractors rely on the VG1245BL for its 200 psi close-off pressure rating and its ability to maintain stable discharge temperatures in air handling units and fan coil units.

Key Benefits for the Contractor:
  • Stainless Steel Internals: The 300 series stainless steel ball and stem prevent premature failure in harsh water conditions.
  • High Close-Off Pressure: Engineered to handle up to 200 psi close-off, ensuring reliable shut-off in demanding hydronic loops.
  • Precise Flow Control: The equal percentage flow insert allows for accurate modulation, reducing hunting and actuator wear.
  • Versatile Compatibility: Standard 3/4" NPT threaded connections and universal mounting for Johnson Controls actuators simplify field installation.
Common Technical Questions:

What is the maximum fluid temperature for the VG1245BL?
This valve is rated for fluid temperatures ranging from 23?F to 203?F (-5?C to 95?C) in non-condensing environments.

Can this valve be used for steam applications?
No, the VG1245BL is specifically designed for water and glycol solutions; it is not rated for steam service.

Does this valve require a specific mounting orientation?
While the valve can be mounted in various orientations, it is standard practice to avoid mounting the actuator below the horizontal plane of the pipe to prevent condensate damage.
