Product features

Pneumatic screw ball valve is composed of internal screw ball valve and pneumatic actuator, which can be divided into integral type (one piece type), two-piece type and three piece type according to different structural forms. Because the valve itself is small in size and compact in structure, it is especially suitable for working conditions with limited installation size and relatively narrow space. The pneumatic threaded ball valve uses compressed air as the power source to operate the opening and closing of the ball valve. Double acting or single acting actuators can be selected according to the work needs. The single acting form has the function of spring return, which can automatically return to the open or closed state in case of failure or disconnection of the air source.
Advantages of pneumatic threaded ball valve:
1. A manual operating mechanism can be installed on the top or bottom of the actuator to manually open and close the valve.
2. The internal thread pneumatic ball valve has the advantages of small size, 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. It has a wide range of applications, ranging from a few millimeters to several meters in diameter, from high vacuum to high pressure.
5. The pneumatic threaded ball valve adopts a bottom mounted structure with a reverse seal, and the valve stem will not be impacted when the valve chamber is abnormally pressurized. 90 ° switch positioning mechanism can be set and locked as required to prevent misoperation.
