Product Description

Product design and manufacture according to ASME B16.34, E101 standards, can be used with imported equipment.

2. The valve cavity adopts pressure self-tightening sealing structure, the higher the pressure of the inner cavity, the better the sealing performance.
3. The two ends of the branch pipe are butt welded to meet different nozzle requirements.
4. The sealing surface of the valve disc and seat is made of slite cobalt-based cemented carbide surfacing, which has good wear resistance, high temperature resistance, good abrasion resistance and long service life.
5. The valve cover packing box is reasonable, the filler is added with corrosion inhibitor, the seal is reliable, and the switch is stable.
6. The valve has an upper sealing structure to ensure that the valve stem will not leak when the valve is opened and running.
