Type 2658

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 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.
