Features:
1. Seat and body are split design for easy maintenance and replacement.
2. The valve body is designed to be open and the axial seal is safer.
3. It adopts an anti-exit structure for valve stem, spring +U type card structure are used in the upper part of the stem, which can not only compensate for installation errors, but also prevent the stem from loosening.
4. Valve plate and seat seal are of ball design, more reliable sealing.
5. Design elastic mechanism at seat end to compensate sealing effect of seat and valve plate.
