The product characteristics of pneumatic valve flange

Pneumatic valve flange is ball valve with pneumatic actuator. Pneumatic actuators to perform relatively fast speed, and does not require hands-on workers, to a great extent, save the human resources and time. Pneumatic flanged ball valves evolved by the globe valve. It has the same rotate 90 degrees to action, different is the cock body is ball, a round hole or channel through its axis. Spherical and opening ratio should be such, that is when the ball rotate 90 degrees, in the inlet and outlet should be completely present spherical, thereby blocking flow. Fluid resistance is small, its resistance coefficient with section of equal length. Simple structure, small volume, light weight. Compact and reliable, the widespread use of plastic ball valve sealing surface of materials, good sealing, also has been widely used in the vacuum system. Easy to operate, open and close quickly, from open to close just rotate 90 °, is advantageous for the remote control. Convenient maintenance, pneumatic ball valve has simple structure, sealing ring, which generally remove replacement is more convenient. In full open or full close, sphere and valve seat sealing surface and the dielectric isolation, medium through, does not cause the valve sealing surface erosion.
