Stainless steel pneumatic clamp hard seal butterfly valve ( External regulation) The picture

Stainless steel pneumatic clamp hard seal condition adjustment of pneumatic valve is a high-performance flow control devices, using three partial hardness sealing structure, not only have two-way sealing function, and has good maneuverability, high pressure resistance, high temperature resistant, etc, when the pneumatic valve opens, pneumatic valve seat and disc almost no wear and tear, long service life, is the industrial pipeline equipment, the key technology of environment under the condition of the worst one of the pneumatic valve performance is remarkable.





stainless steel pneumatic clamp pneumatic valve, hard seal adjustment adjustment is mainly composed of three partial hardness seal butterfly pneumatic valve, assembly or single-acting pneumatic actuators with double acting, match again with the pneumatic valve positioner and related accessories ( Limit switch, sanlian pieces, etc. ) 0 by compression. 4 - 0. 7 mpa clean air source and receiving 4 - 20 ma related analog signal to the controller output signals as a set, at 0 - of pneumatic valve 100% of opening adjustment, so as to control the size of pipe flow!








stainless steel pneumatic clamp hard seal adjustment butterfly pneumatic valve sealing ring choose stainless steel, has the dual advantages of metal hard seal and elastic seal, and close more and more tightly, no matter in the low or high temperature, and the high pressure condition, it can keep good sealing performance and corrosion resistance, and long life of use.
