The advantages of vacuum by pneumatic valve 3

some superiority has its unique structure, vacuum by the pneumatic valve is a relatively new type of pneumatic valve type brake. Such as switch frictionless, seal is not easy to wear and open-close torque is small. Which can reduce the distribution of the specifications of the actuator. With multi-turn electric actuators, which can realize to adjust the medium and carefully cut off. Widely used in petroleum, chemical industry, rural water supply and drainage and other demanding cutting conditions. The pneumatic valve average device.
has the following advantages: vacuum by pneumatic valve in the line is mainly used to do cutting, distribution, and change the flow direction of medium. Brake pneumatic valve is widely used in recent years a new type of pneumatic valve.
the drag coefficient with section of equal length. 。 Fluid resistance is small.
。 Simple structure, small volume, light weight.
the brake of the pneumatic valve sealing surface materials widely used plastic, sealing good,. The compact and reliable. Also has been widely used in the vacuum system.
open and close, quickly. It is easy to operate. From open to close as long as the rotating °, is advantageous for the remote control. Simple structure,
brake pneumatic valve. Easy maintenance. The assembly of seals are generally activities change is more convenient.
the lock body and pneumatic valve seat sealing surface and the dielectric isolation,. Full open or full close. Medium through, does not cause erosion of pneumatic valve sealing surface.
size from small to several millimeters,. Wide range of application. To a few meters from high vacuum to high pressure can be applied. Rotation, the ball into the entrance, shall all be present spherical, thereby cutting flow.
