1. Pneumatic butterfly valve gear type double piston, large output torque, small size.?
2. The cylinder is made of aluminum, light in weight and beautiful in appearance.?
3. Manual operating mechanism can be installed at the top and bottom.?
4. Rack type connection can adjust the opening angle and rated flow.?
5. The butterfly valve actuator can be equipped with live signal feedback indication and various accessories to realize automatic operation.?
6. IS05211 standard connection facilitates the installation and replacement of products?
7. The adjustable screw at both ends can make the standard product have an adjustable range of ± 4 ° at 0 ° and 90 °. Ensure the synchronization accuracy with the valve.?

The outer circle of the butterfly plate of the pneumatic butterfly valve adopts spherical shape, which improves the sealing performance and prolongs the service life of the valve. Zero leakage is still maintained after more than 50000 times of opening and closing under pressure. The sealing elements can be replaced, and the sealing is reliable to achieve two-way sealing. The butterfly plate can be coated according to user requirements, such as nylon or PTFE. The valve can be designed as flange connection and wafer connection. The driving mode can be manual, electric or pneumatic.
