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.

・Recommended use: General purpose on/off

control for HVAC and Sanitary facilities.

・Features: Smooth actuation prevents water

hammer when shutting off the valve.

High close-off, low leakage, and long product life.

Manual lever allows easy valve open/close in

case of power failure.

∆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.
