About the working principle of the pneumatic valve those things you know?

Pneumatic valve in the usual use of the role of more and more big, 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. Usually think valve open and close the most 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 primary 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.
