Product features

Due to its compact structure, it is suitable for small size pneumatic valve. The pneumatic screw ball valve uses compressed air as the power source to operate the opening and closing of the ball valve. According to the work needs, the double acting or single acting actuator can be selected. The single acting type has the function of spring reset, which can automatically return to the open or closed state in case of failure or air source disconnection.
Advantages of pneumatic screw ball valve:
1. Manual operation mechanism can be installed at the top or bottom of the actuator to open and close the valve manually.
2. The internal thread pneumatic ball valve has the advantages of small volume, good sealing, reliable operation, easy maintenance, convenient installation and strong adaptability.
3. The sealing structure is divided into metal seal and elastic soft seal, which can be used in different working conditions.
4. Wide range of application, diameter from small to a few millimeters, large to several meters, from high vacuum to high pressure can be applied.
5. The pneumatic screw ball valve adopts the bottom mounting structure with reverse sealing, and the valve stem will not be impacted when the valve chamber is abnormally pressurized. The 90 ° switch positioning mechanism can be set and locked as required to prevent misoperation.
