Pneumatic butterfly valve flange type structure

pneumatic flange butterfly valve by quarter-turn pneumatic piston of pneumatic valve pneumatic actuator and control valve, the main advantages: simple structure, small size, light weight, low cost, pneumatic pneumatic valve flange plate of the features is especially significant, installed in the upper air tunnel, through two five-way solenoid pneumatic valve control is easy to operate, also can adjust flow medium.
fluid resistance is small, large diameter of the pneumatic flange butterfly valve fully open the effective flow 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 flange butterfly valve sealing material with nitrile butadiene rubber, fluorine rubber, which is suitable for multi-layer metal hard seal plate pneumatic valve seal, has the advantage that the elastic sealing, no matter under the condition of low temperature all have good sealing performance. Therefore, pneumatic flange butterfly valve is widely used in metallurgy, electric power, petroleum, chemical, air, gas, combustible gas and corrosion medium such as water supply and drainage pipeline.
the butterfly pneumatic valve adopts the principle of three-dimensional eccentric design, make the space of the sealing surface movement to achieve ideal, no friction, no interference with each other, together with sealing material is properly selected, so that the adjustment of the pneumatic valve sealing, corrosion resistance, high temperature resistance and abrasion resistance etc. Get a reliable guarantee. Its main characteristics are as follows:
, small open torque, flexible, convenient and saving energy.
, 3 d braided structure, make the butterfly plate is shut tight, reliable sealing performance, zero leakage.
, high pressure resistance, corrosion resistance, wear resistance, long service life, etc.
