Application & Function

1. The design and manufacture of the products meet the requirements of American national standard ANSI B16.34, American BS1873 and other foreign advanced standards.
2. The shape of valve body is barrel shape or streamline shape, which is beautiful. The flow pattern is straight through. The fluid resistance is small.
3. The sealing surface of the closing part (disc) and valve seat is sealed with conical surface, which has small closing force, erosion resistance and reliable sealing.
4. The valve seat can be a replaceable valve seat, which can be combined with the sealing surface material to meet the requirements of working conditions and prolong the service life.
5. According to the need of closing force, the large diameter and high pressure stop valve adopts the lifting rod as the driving mode, and is equipped with rolling bearing type and impact type hand wheel to reduce the closing force.
6. The materials of main body, inner parts, fillers and fasteners can be reasonably combined according to the requirements of users or actual working conditions.
