1. The use of equal-diameter straight-through structure with runner greatly reduces the loss of flow resistance coefficient and energy, and significantly improves the service life and performance of the valve.
2. The valve chamber adopts pressure self-tightening sealing structure, which has good sealing performance.
3. The sealing surface of gate and seat is made of cemented carbide surfacing, which has good wear resistance, high temperature resistance, corrosion resistance and abrasion resistance.
4. The surface of the valve stem has good corrosion resistance and abrasion resistance after corrosion-resistant nitriding treatment.
5. The structure of hoist can be designed into single board, double board and parallel double board according to user's requirements.
