Control Ball Valves

VBF2 Two-way Flanged Control Ball Valve

The VBF2 Two-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 leakage specification (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
