Product features
working principle
The control ball valve is driven by the angular stroke actuator. The actuator receives the standard regulating or three state floating-point signal and rotates the valve ball (throttling element) to the position indicated by the control signal.
Equal percentage characteristic
The built-in port plate ensures equal percentage flow characteristics
