Description

Features
 

  • Mode of operation The characterized control valve is operated by a rotary actuator. The actuator is controlled by a standard modulating or 3-point control system and move the ball of the valve – the throttling device – to the opening position dictated by the control signal. Open the ball valve counterclockwise and close it clockwise.

  • Flow characteristic Equal-percentage characteristic of the flow rate ensured by the integral characterizing disc.
