The characteristics of the pneumatic valve and then you don't know the secret!

Pneumatic valve is used to control fluid flow, pressure and flow to a device that has an important role in fluid conveying system. And with the continuous development of products, in the role of the use of more and more at ordinary times, it gradually replaces the other valve type, the valve type has more advantages. Pneumatic valve only need gas rotation operation and small rotational torque can be closed tightly. Completely equivalent medium valve body cavity to supply the flow resistance is small, straight. Generally thought that open and close valve suitable for a direct use, but recent development has been planned to valve as giving it a throttling and control flow. Pneumatic valve itself is the key characteristic of compact structure, easy to operate and repair, suitable for water, solvents, acids and usually work media such as natural gas, and it is suitable for the operating conditions of medium, such as oxygen, hydrogen peroxide, methane and ethylene. Pneumatic valve body can be all, also can be combined. Pneumatic actuators to perform relatively fast speed, and does not require workers to do, to a great extent, save the human resources and time. Pneumatic valve is evolved by the cock. It has the same rotation action, different is the cock body is a body, has a circular hole or channel through its axis. And the opening of the share should be so, that when the rotation at the inlet and outlet shall all be appeared, and then cut off the flow. Pneumatic valve need only through compressed air into the pneumatic actuators, air core rotates - Degree of operation and small rotational torque can control valve switch, can be applied according to the working condition of demand valve locator, thus opening to medium flow control valve core. Body around the center line of the valve body rotation to achieve open, has a circular hole or channel through its axis. Beware of rotation to °; When the valve is in closed state, when the actuators work, just a small rotational torque to the valve shut tightly, which can achieve fast truncation to cut off the principle. Characteristics: ） Fluid resistance small, full size valve with little flow resistance. （ ） Simple structure, small volume, light weight. （ ） Closely. It has two sealing surface, and the valve sealing surface using the plastic material, good sealing, can realize the seal. Have also been used in the vacuum system. （ ） Convenient operation, opening and closing fast, from open to close as long as the rotating °, is advantageous for the remote control. （ ） Easy maintenance, the structure is simple, sealing ring, which generally remove replacement is more convenient. （ ） In full open or full close, the body and seat sealing surface and the dielectric isolation, medium through, does not cause the valve sealing surface erosion. （ ） Apply widely, size from small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied. （ ） Because of the valve in the opening and closing process to wipe, so can be used to bring in the medium of suspended solid particles.
