D343H type PN6~PN25 worm gear drive triple eccentric hard seal butterfly valve

[product use]
D343H type metal hard seal butterfly valve adopts precise j-shaped elastic sealing ring and three-eccentric metal hard seal structure. It is widely used in the industrial pipelines with medium temperature ≤425℃, such as gold, electric power, petrochemical, water supply and drainage, municipal construction, etc., for regulating the flow rate and carrying the cut-off body.
【 product features 】
1, the metal hard seal butterfly valve adopts the three-eccentric sealing structure, the valve seat and disc almost no wear, with the sealing function of tighter and tighter;
2. The sealing ring is made of stainless steel, which has the double advantages of metal hard seal and elastic seal. No matter in low temperature or high temperature, it has excellent sealing performance, corrosion resistance and long service life.
3. The sealing surface of butterfly plate is made of surfacing cobalt-based hard alloy. The sealing surface is abrasion resistant and has a long service life.
4. Large size butterfly plate adopts quilted structure with high strength, large overflow area and small flow resistance;
5, metal hard seal butterfly valve with two-way sealing function, installation is not limited by the direction of the medium, nor affected by the space position, can be installed in any direction;
6. The drive device can be installed at multiple stations (rotating 90° or 180°), which is convenient for users to use. The product can be used in petroleum, chemical, pharmaceutical, chemical fertilizer, electric power and other industries.
The product conforms to the standard: JB/T 8527. No Information
