Product Description
1/2" MOTORIZED BALL VALVEOverview
The VBN2 Two-Way Control Ball Valves control hot and chilled water in HVAC systems to provide two-position or modulating functions. Order them with or without factory-mounted non-spring return or spring return direct-coupled actuators.
Features
- Sizes from 1/2 to 3 inches with internal (female) NPT connections.
- Equal percentage or linear flow characteristics.
- Choice of four, factory-installed actuation control schemes: Floating, Modulating (2-10 V), Spring Return 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 seat leakage specification (0.01% of Cv).
- Optional NEMA 3R (IP54) rated enclosure for outdoor applications.
- Actuator can be mounted on the valve in any of four positions.
- Field-serviceable stem assembly.
- Wide Cv choices from 0.38 to 266.
- Nickel-chrome plated brass or 316 stainless steel ball and stem.
