Stainless steel pneumatic butterfly valve by pneumatic actuators and flange of three partial hardness seal butterfly pneumatic valve, pneumatic valve and pneumatic valve plate are made of stainless steel material, pneumatic valve seat adopts metal hard seal multi-level structure, corrosion resistance, high temperature resistance and abrasion resistance and other characteristics, widely used in environmental protection, petroleum, chemical, gas, and the pipeline corrosion media such as water supply and drainage.
Pneumatic hard seal butterfly valve in the pipeline on the main cutting and throttling effect, can be designed to have a regulation or pneumatic valve and regulating function.
stainless steel pneumatic hard seal butterfly valve on 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 wear resistance has been a reliable guarantee. Open-close part is a circular disc, the use of pneumatic actuator air pressure to control pneumatic valve, used mainly for truncation of pneumatic valve, pneumatic valve positioner can assemble, enter 4 Analog signal of 20 ma, adjusted by the parameters of medium.
pneumatic flange hard seal butterfly valve structure principle:
D643H - 16 p pneumatic pneumatic valve flange hard seal butterfly valve stem axis between the butterfly plate sealing surface and bias, and with the pneumatic valve body channel axis offset, pneumatic seat and pneumatic rotary axis body form an eccentric Angle channel axis, so the formation of triple eccentric. Butterfly pneumatic valve & from 0 deg; ~ 90度; Open when the butterfly plate seal face moment in open immediately from pneumatic valve seat sealing surface, in its 90 & deg; ~ 0度; Closing, the butterfly plate cone sealing surface will contact and pressure pneumatic conical seating. So pneumatic seat with no friction between the sealing surface of disc, in addition to the wear and the possibility of leakage.
