Type 2658 2/2-Way Ball Valve with Pneumatic Rotary Actuator
Brand: Burkert Fluid Control Systems
The complete unit of the Type 2658 consists of 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 cross section.
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.
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 prevents these separating during operation.
