Features

• Mode of operation The characterised control valve is operated by a rotary actuator. The actuator is controlled by a standard modulating or 3-point control system and moves the ball of the valve – the throttling device – to the position dictated by the control signal. The valve is opened counterclockwise and closed clockwise.

• Flow characteristic Equal-percentage flow control is ensured by the integrated characterising disc.

• Patent Applied for.
