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
