Single and double) Flush the cock pneumatic valve

( Double flush cock pneumatic valve, close or the rotation of the plunger type pneumatic valve, through the rotation degrees of the fortress of the pneumatic valve opening and pneumatic valve body in the same or separate, spilling a pneumatic valve is opened or closed. The shape of the cock of the pneumatic valve pneumatic valve plug into cylindrical or conical. In cylindrical pneumatic valve plug, the channel general rectangular; In the pneumatic valve plug taper, channel into a trapezoid. The shape of the structure of the pneumatic valve cock become light, but also produced a certain loss. Pneumatic valve is best suited for cock as cut off and on medium and diversion, but according to the applicable properties and sealing surface erosion resistance, sometimes also can be used for throttling. http://www。 zgbfw。 com/info/
