Structure feature
1. On-off no abrasion: Ball rotates after departure from seat, so that can eliminate the sealing surfaces abrasion, to solve the abrasion problems about traditional ball valve seat sealing surface and balls.
2. Torque operation: Due to there is no friction between seat and ball, its very easy for stem operation. Therefore we usually use hand wheel operation for ball valve instead of worm gear operation and others except the big size ball valves.
3. Single-seat design: The static single-seat valve installation can ensure bi-directional zero leakage, and avoid the problem of cavity pressure increase in double-seat valve.
4. Anti-wear hard sealing face: Bead welding ball with a layer of hard alloy steel and polished to meet the harsh working condition with reliable sealing performance.
5. Self-cleaning: When the ball separate from the seat, the fluid in pipeline will flow through the ball equally along the sphere sealing surface degree 360. Not only eliminated the partial erosion by high-speed fluid on valve seat, but also washed away the accumulation substances on the surface, then come to purpose of self-cleaning, eliminating the effect of accumulation to seal performance.
6. Top entry type: Top entry ball and seat design, so we can check and maintain without disassembling the body in the line.
7. Seat sealing face metal protection: Strengthened PTFE corrugated with metal seat, so that the seat metal sealing surface can get the good protection.
8. Wedge-shaped seal structure: The mechanical force of valve is provided by stem, force the ball on the seat and then sealed. So the valve sealing performance is not influenced by pipeline pressure. Therefore, make the sealing performance reliable in various conditions.
