• Straight-through flow between A and AB ports.
• 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.
