Jacket brake type metal hard seal butterfly pneumatic valve standards

with brake type metal hard seal butterfly pneumatic valve products overview
with brake type metal hard seal butterfly pneumatic valve is in the multi-level triple eccentric metal hard seal butterfly pneumatic valve, on the basis of the development of a new product. In addition to a multi-level triple eccentric metal hard seal butterfly all excellent properties of pneumatic valve, also can two-way pressure, the pneumatic valve is one of the biggest advantage is that can implement on site maintenance. With the selection of pneumatic valve body material, the use of temperature from - ℃ ~ ℃, due to its good flow can be closed cutting medium, can also be adjusted medium flow.
with brake type metal hard seal butterfly pneumatic valve product features:
with brake type metal hard seal butterfly pneumatic valve is mainly composed of pneumatic valve, pneumatic valve cover, disc, pneumatic valve shaft and pneumatic valve sealing ring, the disc sealing ring, shaft sleeve, bottom cover, driving device and so on, has the following characteristics:
jacket sluice structure solves the traditional eccentric butterfly pneumatic valve can not at the scene maintenance problems. Multi-level triple eccentric butterfly pneumatic valve in accordance with the original in the past, when sealing ring damaged, need to back to manufacturers repair or remember a butterfly pneumatic valve scrap. Jacket brake type pneumatic valve adjustment need to be removed from the pipeline, it only takes few time to open the pneumatic valve cover can together with the pneumatic valve stem and disc from the pneumatic valve body cavity to repair or replace the sealing ring, then cover the pneumatic valve bonnet seal snappy, pneumatic valve can be realized during the maintenance can not affect the normal operation of the pipeline system, the maintenance of pneumatic valve to minimize the benefits of the damage;
with multi-level triple eccentric metal hard seal butterfly all excellent properties of pneumatic valve;
reliable sealing function, no leak of gas seal;
butterfly plate streamline design with high intensity, large flow area, small flow resistance, save energy; Pneumatic valve design, manufacture according to GB/T - The general pneumatic valve flange and connected to the clamp butterfly valve ',
JB/T - The metal sealing butterfly pneumatic valve; Pneumatic valve pressure test in accordance with GB/T - The general pneumatic valve pressure test,
JB/T - The pneumatic valve of inspection and test; Pneumatic valve structure length according to the GB/T - The length of metal structure of pneumatic valves; Flange connection size in accordance with the: GB/T. - The plane, convex integral steel pipe flange.
