Johnson Controls VG18A5KS 3-Way 2-1/2" Flanged Ball Valve Cv47 ASME Class 150 Stainless Steel Trim

The Johnson Controls VG18A5KS is a 3-way, 2-1/2 inch flanged ball valve from the VG1000 Series, designed for precise flow control in commercial and industrial HVAC applications. The valve features a forged brass body with a 300 series stainless steel ball and stem assembly, providing reliable performance across a broad range of fluid temperatures and system pressures.

Rated at Cv 47 with an ASME Class 150 flanged connection, this valve meets tight shutoff requirements with a 50 psi closeoff pressure rating for three-way configurations. It is suitable for hot water, chilled water, 50/50 glycol solutions, and low-pressure saturated steam service, making it a versatile choice for hydronic systems.

Key Features:

• 3-way flanged ball valve, 2-1/2 inch connection size
• Cv flow coefficient: 47
• Forged brass valve body with ASME Class 150 flanged end connections
• Stainless steel ball and stem for high-temperature water (0°F to 284°F) or 25 psi saturated steam service
• 50 psi closeoff pressure rating (three-way configuration)
• Narrow face-to-face design
• Graphite-reinforced PTFE seats for extended service life in iron-oxide contaminated water systems
• Amodel® flow characterizing disk for equal percentage flow characteristics
• 500:1 rangeability for accurate control under all load conditions
• Compatible with Johnson Controls M9000 Series electric actuators (actuator sold separately)
• Valve only — no actuator included

The VG18A5KS is part of the VG1000 Series flanged ball valve lineup and is designed to accept factory or field-mounted spring return or non-spring return actuators. It is the recommended replacement platform for legacy VG2000 Series flanged globe valves in equivalent applications.
