D673H pneumatic clip-metal sealing butterfly valve
D673H pneumatic clip-on flexible metal sealing butterfly valve with a "U" shaped stainless steel ring, the precise elastic sealing ring in contact with the three-dimensional eccentricity of the polished disc. Traditional eccentric butterfly valve to open and close the ills from 0 ° to 10 ° instantaneous sealing surface is still in sliding contact friction disc sealing surface in the opening moments, separation, close contact that the sealing effect, to prolong the service life of sealing performance the best purpose. Which is widely applied to the medium temperature ≤ 550 ° C, metallurgy, electric power, petroleum, chemical, air, gas, combustible gas and water supply and drainage, corrosive media channels, the best device to regulate flow and truncated fluid.
Feature

       1, the butterfly valve structure is simple, compact, light weight, easy installation and removal, easy maintenance;
       2, the butterfly valve of stainless steel "U" type seals, with a certain degree of flexibility in terms of heat, cold case and disc has a good seal;
       3, the three-dimensional eccentric butterfly valve from the rigorous calculation of the "U"-ring and the disc is almost no friction, long life, and has a more closed more tight functions;
       4, disc sealing surface using the surfacing cobalt carbide, sealing surface wear resistance, long service life;
       5, the structure of the butterfly valve is a unique "switch" just turn the valve stem 90 ° to complete. Flexible, convenient, and effort, not the level of impact of the media pressure, sealing performance and reliable;
        6, high temperature, low temperature resistance, corrosion resistance.

Electric clip-on hard sealing butterfly I plant the introduction on the basis that foreign advanced technology, and precision J-shaped elastic sealing ring and three eccentric and multi-level metal seal structure, electric clip-on hard sealing butterfly valve is widely used in The medium temperature ≤ 425 ° C, metallurgy, electric power, petrochemical, and water supply and drainage, and municipal construction and other industrial piping, and for regulating traffic and set out the drying body. Electric three-eccentric structure of clip-on hard sealing butterfly valve, valve seat and disc sealing surface hardness and stainless steel, has a good corrosion resistance, long life, electric clip-on hard sealing butterfly valve are two-way sealing function, the product complies with the countries the GB/T13927-92 valve pressure test standard.
Electric clip-on hard sealing butterfly valve characteristics
1, electric clip-on hard sealing butterfly valve triple eccentric sealing structure, seat and the disc is almost no wear, the more the concept of more tight sealing function.
2, the ring made of stainless steel production, with the dual advantages of the metal seal and elastomeric seals, both in the case of low and high temperatures, with excellent sealing performance, corrosion resistant, long life characteristics.
3, the disc sealing surface surfacing cobalt based cemented carbide, sealing surface wear resistance, long service life.
4, large-format disc using a truss structure, high strength, flow area, flow resistance is small.
5, electric clip-on hard sealing butterfly valve with bi-directional sealing, installation without the limitations of the medium flows are not subject to the impact of spatial location, can be installed in any direction.
6, the drive can station (rotated 90 ° or 180 °) to install, user-friendly.
