7. Suitable for wide use, size QiXiaoEr to several millimeters, big to a few meters, from high vacuum to high pressure can be applied. 。 8. The pneumatic ball valve power supply right and using gas, common to 0. 2 - 0. 8 mpa pressure, phase comparison safer. ) Pneumatic ball valve has been widely used in the fuel, chemical, power, papermaking, atomic energy, aviation, rockets and other departments, and many people in the daily life. Ball valve itself is the main distinctive local compact structure, easy operation and maintenance, suitable for use in water, solvents, acids and natural gas and other medium of general office, and also suitable for use in conditions of despicable medium, such as oxygen gas, oxygen, hydrogen, methane and ethylene, etc. The proportion of the surface of the ball and intersection should be so, that is when the ball rotate 90 degrees, on the surface of the inlet and outlet should be all flash ball, so cut off the flow. Pneumatic ball valve is in recent years is widely considered and appropriate use of a new type of valve, it has the following advantages: 1. Fluid resistance is small, the resistance coefficient and its long section of Marine valve equivalent. Absolute equality of the valve body cavity to supply medium with a small resistance and also flow through. It rotates 90 degrees with the same action, different is the cock body is spherical stereo, a round hole or channel through its axis. 5. Maintenance is convenient, the pneumatic ball valve structure simple, tightly closed circle ordinary activities, remove the transform are convenient. Ball valve body can be a group, also can be combined. 6. On the paper or full close, spherical stereo and seat tightly closed surface from the media, media, won't be moved on the surface of the valve tightly closed denudation. 2. Simple structure, big and small, light weight. Pneumatic ball valve in pneumatic actuators help body to rotate 90 degrees, can be successfully implemented for medium flow cut off and the function of the channel. Generally think that the most open and close fitting for direct do use ball valve, ball Industrial Valves but recent developments have preset into with throttling and stem flow. 4. Convenient operation, opening and closing a sudden, from the whole piece of paper to seated just rotate it 90 & amp; 度; For easy distance of the stem. This kind of valve is installed in the pipeline can be arbitrary position. Q: the principle and advantages of answer: pneumatic ball valve pneumatic ball valve is by developing and plug valves. If air leakage, pneumatic ball valve relative hydraulic, electric, gas can directly discharge, no pollution to the background, at the same time have a higher security. And takes small rotational torque can close the tightness. 9. Compared with the manual and turbine in fixed ball valve, pneumatic ball valve can be large diameter with decorate, ( Manual and turbine in moving ball valves are below 12 caliber, pneumatic ball valve can achieve 48 ') diameter up to now. 3. Emergency reliable, up to now ball valve tightly closed surface materials widely used molecular compound plastic, tight sealing ability is good, have been widely used in the vacuum system. Pneumatic ball valve in the line is mainly used for cutting speed, distribution, and changes the flow direction of medium. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
