burkert 2658 A/I球阀DN10-50 The complete unit of the Type 2658 consists of a pneumatic rotary actuator and a ball valve body from plastic. burkert 2658 A/I球阀DN10-50 The connection between the ball valve and the actuator is made via a standard interface (fl ange 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-operated ball valve can be used for a wide range of applications and media. The pneumatic rotary actuator can also be used for other purposes.
