Beijing, Tianjin metal seal butterfly agent Which metal seal butterfly _ Recruitment agents, Henan standard light valve for metal seal butterfly who watch the entire structure of the eccentric metal seal structure from the outside, sealing in the form of metal-to-metal sealing can exchange the metal to metal seal ring, stainless steel and graphite composite panels to metal seal ring. Metal seal butterfly form in addition to the electric drive are: manual, worm gear lever, pneumatic. After research and draw metal seal butterfly butterfly plate installed on the pipe diameter direction. Cylindrical channel in the valve body, disc-shaped disc around the axis of rotation, rotation angle between 0 ° ~ 90 °, rotated to 90 °, the valve was fully open state. Metal seal butterfly valve Features: 1, metal seal butterfly valve with three eccentric seal structure, seat and disc almost no wear, with the view of the tight sealing function. 2, ring made of stainless steel production, with a metal seal and elastic sealing of the dual advantages, both in the case of low and high temperatures, all with excellent sealing performance, corrosion resistance and long service life. 3, the disc sealing surface using cobalt-based alloy welding, sealing surface wear resistance and long service life. 4, large-sized disc using lattice structure, high strength, flow area, flow resistance. 5, with two-way metal sealing butterfly valve sealing function, the installation of unrestricted flow of media, are not subject to influence spatial location can be installed in any direction. 6, the drive can be multi-position (rotated 90 ° or 180 °) to install, easy to use.
