This valve contains two valves in a valve, simultaneously performing balancing and control. it is equipped with balancing valve function, which absorbs a differential pressure and regulates a pressure, and control valve function, which controls a flow by actuator.

It adopted a new concept new IS mechanism. this new mechanism was intended that an actuator automatically calculates and operates valves, controlling a flow as entered by a user(without a user's manual calculation). In addition, it is equipped with UI(User Interface), which was developed so that a user directly enters a flow value, enabling dynamic a flow to be set simply by setting a motor's open rate. Hence, an active constant flow control valve, this valve improves a user's convenience and avoids energy waste by means of accurate flow control.
