The principle and characteristic of pneumatic butterfly pneumatic valve to the clamp

pneumatic butterfly pneumatic valve is used to the clamp with the rotation of the pneumatic valve butterfly orange circular disc to do, to be opened in order to realize the opening action. Pneumatic butterfly pneumatic valve to the clamp used mainly for truncation of pneumatic valve, can be designed to have a adjustment or period of pneumatic valve and adjustment function, the current disc pneumatic valve on the low voltage and medium caliber pipe used more and more.
pneumatic butterfly pneumatic valve to the clamp of the main advantages: simple structure, small volume light weight, low cost, the pneumatic adjustment to the clamp pneumatic valve installed in the upper air tunnel, through two five-way solenoid pneumatic valve control is easy to operate, also can adjust flow medium. This characteristic is especially striking. Fluid resistance is small, large diameter pneumatic drive pneumatic valve fully open effective circulation area is larger, easy opening and closing fast, disc pull rotation Angle can complete opening and closing, due to the rotation axis disc plate hand medium force nearly equal, and the torque in the opposite direction, thus opening and closing torque is small, low pressure can achieve good sealing, pneumatic butterfly pneumatic valve sealing materials to the clamp with nitrile rubber, fluorine rubber, rubber, four fluorine lining so sealed performance is good, which is suitable for hard and soft hard seal plate pneumatic valve cascading sheet metal, metal hard seal and heavy advantage of elastic sealing, no matter under the condition of low temperature all have good sealing performance.
