Overview

Stainless steel ball valves with pneumatic actuators are mainly used to cut off or connect the medium in the pipeline, and can also be used to regulate and control the fluid.

Characteristic

1. The fluid resistance is small;
2. The thrust bearing reduces the frictional moment of the valve stem;
3. The sealing ring made of elastic material such as polytetrafluoroethylene is easy to seal, and the sealing capacity of the ball valve increases with the increase of the medium pressure;
4. Rack and Pinion Pneumatic Actuator with aluminium alloy body;

5. The actuator can choose signal feedback indicator and various accessories to realize automatic operation;

6. The IS05211 standard connection provides convenience for product installation and replacement.
