O type pneumatic valve _ pneumatic components factory valve industry internal structure of the system

Pneumatic pneumatic valve type O pneumatic valve is a valve pneumatic components factory owners to produce one of the pneumatic valve, has good sealing performance, long life and other characteristics; O type pneumatic valve is zui widely used products on the market at present, the following details O internal structure and characteristics of pneumatic valve so that the customer further understand. O type pneumatic valve is a quarter-turn cut-off valve, the products are widely used in papermaking, chemical fiber, food, chemical, petrochemical, environmental protection and other industrial department of automatic control system. O type pneumatic valve features: 1, O type pneumatic valve adopts fixed pneumatic design, up and down the stem has two bearing positioning, high mechanical stability, small starting torque, bearing the use of special self-lubricating bearings, to avoid the stuck phenomenon of valve in use for a long time. 2, O type pneumatic valve adopts double metal valve seal or soft seal structure, the valve seat and valve core is always fit closely, movable sealing structure of valve sealing pair wear in use for a long time the automatic compensation function, so it is of long service life and has a great deal of shear capacity and self-cleaning function, especially for control of fiber and particle medium. 3, because of sealing in both directions, so the flow direction of medium body does not need to consider when installation, and the sealing performance is superior, the metal hard seal seat tightness level up to level 5, soft seal zero leakage. 4, small flow resistance, pneumatic valve is one of the valve class zui small flow resistance, its full size pneumatic valve flow resistance is negligible, even reducing pneumatic valve is also quite small flow resistance. 5, quickly switch, pneumatic core is just around the seat 90 ° can complete the full open or close, it is easy to achieve rapid cut off. 6, pneumatic valve according to the different working conditions, can provide hard seal and soft seal seat, soft seat spray welding carbide and tungsten carbide is used to meet the requirements of different occasions. 7, O type pneumatic valve selection of flexible pneumatic actuator or electric actuator, control units, to apply to various industry automation control system. : O cut the working principle of the pneumatic valve switch electric four-way valve _ _ floating pneumatic four-way valve pneumatic valve sealing function and working principle of pneumatic valve pneumatic valve ( Figure)
