VBF3 Three-way Flanged Control Ball Valve
The VBF3 Three-Way Ball Valve Assemblies, with and without 
actuators, control hot and chilled water with glycol solutions up to 
50% in closed loop heating, ventilating, and air conditioning (HVAC) 
systems to provide two-position or modulating functions. These 
valve assemblies can be ordered with or without factory-mounted 
non-spring return or spring return direct-coupled actuators (DCA).
• Sizes from 4 to 6 inch with ANSI Class 125 flanged connections 
• Equal percentage or linear flow characteristics 
• Choice of four, factory-installed actuation control schemes: 
Floating, Modulating (2-10 V), Spring Return 24V 2-Position, 
Spring Return Modulating/Floating 
• Field configurable for normally open or normally
• closed fail-safe position
• Removable manual operating handle to control valve
• during installation or in an event of power failure 
• ANSI Class IV A-port seat leakage (0.01% of Cv) 
• Optional NEMA 3R (IP54) rated enclosure for outdoor applications 
• Option of four actuator mounting positions on the valve 
• Wide range of Cv choices from 91 to 650 
• Valve ball and stem 316 stainless steel 
• Non-isolating mixing or diverting control
