2-way Flange Actuated Control Ball Valve

Overview

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.

Features

• 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.
