Pneumatic valve gate is the use of a pneumatic valve is very wide

the pneumatic valve is a broad, general diameter DN of mm or cutting machine with pneumatic valve is used to cut off it is sometimes a small device also use pneumatic valve, brake by pneumatic valve has the following advantages: first, the fluid resistance is small. Medium flows through the pneumatic valve don't change the direction of flow, the fluid resistance is small. Secondly, a smaller force to open and close. Third, do not restrict the media flow. Fourth, fully open, medium erosion than by the pneumatic valve sealing surface of work. Fifth, the relatively simple shape casting technology better.
brake of the pneumatic valve faults: first of all, the opening and closing time, length, height, and a large, open height size larger. Large space needs to be installed. Second, easy to damage the sealing surface, in the process of closing, the relative friction between the sealing surface, easy to cause scratches. Third, the structure is complex. Pneumatic valve sealing surface, usually have two to machining, polishing and increasing difficulty, more parts and components, manufacturing and maintenance more difficult, the cost more than the high by the pneumatic valve.
