Attention should be paid to the selection of pneumatic ball valve:
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 switch is light, small in size, can be made into a large diameter, reliable in sealing, simple in structure, easy to maintain, the sealing surface and the spherical surface are often closed, and it is not easy to be eroded by the medium, and it is widely used in various industries.
2. The pneumatic ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline.
3. Pneumatic ball valve is a relatively new type of ball valve. It has some advantages unique to its own structure, such as frictionless switch, non-wearing seal, and small opening and closing torque. This can reduce the size of the actuator. Equipped with a multi-turn electric actuator, it can realize the adjustment and close shut-off of the medium.
Pneumatic ball valve model representation method:
Ball valve additional code: V means the valve core has a V-shaped structure, D means low temperature, B means heat preservation, P means eccentric structure, U and S and DY mostly mean top-mounted type;
Ball valve name code: Q means ball valve;
Ball valve drive code: 6 means pneumatic;
Code of connection method: 1 means internal thread, 4 means flange type, 6 means welding, 7 means wafer type;
Structure type code:
Floating type: 1 means straight flow channel, 2 means Y-type tee, 4 means L-type tee, 5 means T-type tee;
Fixed: 0 means hemispherical straight, 6 means four-way flow channel, 7 means straight flow to, 8 means L-type tee, 9 means Y-type tee;
Sealing material code: B babbitt alloy, F fluorine rubber, F46 lining fluorine, H stainless steel, J rubber lining, M Monel alloy, N nylon plastic, Monel P, Y cemented carbide, W valve body directly processed;
Pressure rating code: 16 means the pressure is 16 kg (1.6Mpa), the maximum can reach 64Mpa; 150LB means the American standard pound pressure, the maximum pressure rating can reach 2500LB;
Valve body material code: A titanium and titanium alloy, C carbon steel, I chromium molybdenum steel, P series stainless steel, R series stainless steel, S plastic.
