  • $281.00


The Johnson Controls VG1245ES is a heavy-duty 1-1/2 inch NPT ball valve engineered for precision control in chilled or hot water systems. Featuring a 46.8 Cv flow coefficient, this two-way control valve utilizes an equal percentage flow characteristic to ensure stable thermal output through a wide range of actuator positions. The forged brass body is paired with stainless steel trim, including the ball and stem, which provides superior resistance to corrosion and prevents premature seal failure in high-demand HVAC hydronic systems. Designed for seamless integration with VA9104, VA9203, and VA9208 series actuators, the VG1245ES ball valve utilizes a field-replaceable blowout-proof stem and high-temperature graphite-reinforced PTFE seats. This HVAC control valve is rated for fluid temperatures up to 284°F and static pressures up to 580 psi, making it a reliable solution for commercial building automation and modulating flow control applications.

Key Benefits for Technicians
  • Corrosion Resistance: The 300-series stainless steel ball and stem prevent pitting and scale buildup in aggressive water conditions.
  • Precise Throttling: The integrated Ametal flow-characterizing disk allows the equal percentage flow to match the heat transfer curve of the coil.
  • Reduced Torque: Low-friction PTFE seats minimize the torque requirements for actuators, extending the service life of the valve linkage.
  • Maintenance Efficiency: Blowout-proof stem design allows for safe operation even during high-pressure transients in hydronic heating loops.
Common Technical Questions

What is the maximum differential pressure for the VG1245ES?
This 1-1/2 NPT control valve is typically rated for a maximum close-off pressure of 100 psi, though actual performance depends on the torque rating of the attached actuator.

Can this valve be used for steam applications?
The VG1200 series with stainless steel trim is specifically designed for water and glycol solutions (up to 50%). It is not rated for saturated or superheated steam service.

Which actuators are compatible with the VG1245ES?
It is standardly paired with Johnson Controls VA9000 series electric actuators using the M9000-520 linkage kit for easy field or factory mounting.
