Hard seal butterfly characteristics of pneumatic valve (2)

, three partial hardness sealing butterfly pneumatic valve sealing structure, pneumatic pneumatic disc, seat and almost no seal wear more functional view, and stainless steel production, the ring, metal hard seal and elastic sealing the dual advantages of low temperature and high temperature two cases, with good sealing performance, corrosion resistance, long service life, pneumatic valve sealing surface with cobalt base alloy welding, sealing surface wear resistance, long service life, the crystal structure of the disc using large size, high intensity, the flow area, flow resistance, hard seal two-way sealing function, restriction on the installation from the media flow, butterfly is not affected by the spatial location of pneumatic valve can be installed in any direction, the driver can transfer ( Rotating ° or °) Installation, the user site keywords: pneumatic ball valve pneumatic ball valve pneumatic pneumatic valve pneumatic pneumatic valve pneumatic butterfly valve pneumatic butterfly valve pneumatic actuator pneumatic execution
