Features
■Small and light weight. Valve and Actuator
intergrated as one.
■NEMA 4X and IP54 enclosure allows for the use
inside Air Handling Units (AHU) and in the
outdoors.
■Low power consumption and long product life.
■Equal percentage flow characteristics suited for
AHU Control.
■100:1 range ability controls from low to high flow
rate precisely.
■Flow-to-close structure using differential pressure
across valve realizes low leakage performance.

∆P across valve is measured by built-in pressure sensors.
There is Valve Inherent Capacity Value-curve table loaded to actuator.Valve Inherent Capacity Value is determined by the valve opening.tt
When ∆P and Valve Inherent Capacity Value are available, ACTIVAL Flow Measurement Model calculates Flow Rate.
