The complete unit of the Type 2658 consistsof a pneumatic rotary actuator and a ball valve body from plastic. The connection between the ball valve and the actuator is made via a standard interface (flange connection). The rotary movement in the actuator is produced by a linear piston with angled thread coupling. The rotary actuator moves the ball valve through 90°and thereby opens or closes the port crosssection.The compact pneumatically-operatedball valve can be used for a wide range of applications and media. The pneumatic rotaryactuator can also be used for other purposes.Special feature: The ball valves are equipped with the so-called Dual Block® Technology. This system serves as a safety device for the union nuts. It preventsthese separating during operation.
