How many control modes are there for manual operation of electric gas butterfly valve? 2、 Working principle of pneumatic ball valve: the pneumatic ball valve can be closed tightly only by using the pneumatic actuator to rotate 90 degrees with the air source and a small rotating torque. The completely equal inner cavity of the valve body provides a straight flow passage with little resistance for the medium. It is generally believed that ball valves are most suitable for direct opening and closing. The main features of the ball valve are its compact structure, easy operation and maintenance, and suitable for general working media such as water, solvent, acid and natural gas, as well as media with poor working conditions such as oxygen, hydrogen peroxide, methane and ethylene. The valve body of the ball valve can be integral or combined.
、 Third, the progress of the pneumatic butterfly valve itself is also a good foundation for its future development. As a new industry, it will continue to develop new technologies, improve its structural design, make it more convenient to use, and constantly save costs. On the basis of the existing development, its development will only get better and better, so the prospect is also very good.
