1. The working principle of the pneumatic ball valve is to make the valve unblocked or blocked by rotating the valve core. The ball valve is easy to switch, small in size, can be made into a large diameter, reliable in sealing, simple in structure, convenient in maintenance, and the sealing surface and spherical surface are often in a closed state, which is not easy to be eroded by the medium, and has been widely used in various industries.
2. Pneumatic ball valves are mainly used in pipelines to cut off, distribute and change the flow direction of media.
3. Pneumatic ball valve is a relatively new type of ball valve. It has some advantages unique to its own structure, such as no friction on the switch, no wear and tear on the seal, and small opening and closing torque. This reduces the size of the associated actuator. Equipped with a multi-turn electric actuator, it can realize the adjustment and strict cutting off of the medium.
Pneumatic ball valve model representation method:
Additional codes for ball valves: V means that the valve core has a V-shaped structure, D means low temperature, B means heat preservation, P means eccentric structure, U, S and DY mostly mean top loading;
Ball valve name code: Q means ball valve;
Ball valve driving code: 6 means pneumatic;
Connection method code: 1 means internal thread, 4 means flange type, 6 means welding, 7 means wafer type
