Wafer butterfly valve pneumatic valve parameters

adjustment to the clamp pneumatic valve adopts a 'U' shaped stainless steel ring, the precision of the elastic sealing ring and eccentric butterfly plate 3 d contact after polishing. Solve the traditional eccentric butterfly pneumatic valve in the opening and closing ° ~ ° seal face is still in the sliding contact friction moment of ills, realize the butterfly plate in open the instant sealing surface, the separation, close contact with the sealing effect, achieve prolong service life, sealed performance is the best. Therefore is widely applied to the medium temperature ℃ or less of metallurgy, electric power, petroleum, chemical, air, gas, combustible gas, as well as the corrosion medium such as water supply and drainage pipeline, is the best device for adjusting flow and cutting fluid. Characteristics of

, the butterfly pneumatic valve structure simple, compact, light weight, easy to install and disassemble, convenient maintenance;
, the butterfly pneumatic valve adopts stainless steel 'U' type sealing ring, have a certain flexibility in under the condition of high temperature, low temperature, it has to do with the butterfly plate has excellent sealing;
butterfly, the pneumatic valve to the 3 d eccentricity, through strict calculation, 'U' type sealing ring and butterfly plate almost no friction, long service life, and have the function of the closed more and more tightly;
and disc sealing surface using cobalt-based carbide surfacing, sealing surface wear resistance, long service life.
, this butterfly pneumatic valve structure is unique, and only turn the pneumatic valve rod ° 'switches'. Operation is flexible, convenient, energy saving and is not affected by the discretion of the medium pressure, sealed performance is reliable;
, high temperature resistant, low temperature resistance, corrosion resistance.
