The characteristics of pneumatic butterfly valve and the standard is introduced

pneumatic butterfly valve is composed of pneumatic actuators and pneumatic valve adjustment. Pneumatic butterfly valve is used with the pneumatic valve rod rotation of the circular disc to do, to be opened in order to realize the opening action of pneumatic pneumatic valves are used mainly for truncation of pneumatic valve, can be designed to have a adjustment or period of pneumatic valve and adjustment function, the adjustment of pneumatic valve on the low voltage and medium caliber pipe used more and more. Pneumatic butterfly valve categories: stainless steel pneumatic butterfly valve, hard seal pneumatic butterfly valve, soft seal pneumatic butterfly valve, pneumatic butterfly valve is carbon steel.
adjustment according to the mode of connection can be divided into pneumatic valve flange connection, the clamp connection, butt welding, etc.
control pneumatic valve according to the material classification can be divided into carbon steel butterfly valve, pneumatic valve, cast iron butterfly stainless steel butterfly pneumatic valve and so on.
butterfly pneumatic valve according to the transmission mode can be divided into pneumatic valve, manual butterfly turbine butterfly pneumatic valve, pneumatic valves, electric butterfly pneumatic butterfly valve, etc.
characteristics of pneumatic hard seal butterfly valve:
because this product adopts pneumatic valve adjustment of the design principles of three-dimensional eccentric, 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 wear resistance has been 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
