pneumatic three-piece clamp ball valve has double-acting and single-acting (spring return), rack and pinion transmission, safe and reliable; large-diameter valves adopt series G-type pneumatic actuators fork-type transmission, with reasonable structure and large output torque, There are double-acting and single-acting.
1. Gear type double piston, large output torque and small volume.
2. The cylinder is made of aluminum and gold, with light weight and beautiful appearance.
3. Manual operation mechanism can be installed at the top and bottom.
4. Rack-type connection can adjust the opening angle and rated flow rate.
5. The actuator can be equipped with live signal feedback indication and various accessories to realize automatic operation.
6. IS05211 standard connection provides convenience for product installation and replacement.
7. The joint screws adjusted at both ends can make the standard products have an adjustable range of 4 degrees at 0 degrees and 90 degrees. Ensure synchronization accuracy with the valve.
