Metal Sealing Ball Valve, High Temperature Ball Valves
Design Feature
- Spring-loaded sealing structure provide double block function & optimum performance & tight shutoff.
- Cutting design seat enables to remove slurries, muds or solid mediums adhered to ball or seat
- Gemented carbide coating on ball rim provides better performance of anti-corrosion. Double-scraper design is optional.
- Gland flange design efficiently supports a tight stem sealing by auto-matic compensation, and reduces maintenance costs.
- Seat with broad hard-face offers high performance in sealing, and extends its life. Ball and Seat Lapped by high precision CNC ensure a firm integration.
- Drain design for easy cleaning on pipeline (available on 4" & greater sizes. Smaller sizes available upon request)
- Ball and seat hardened with tungsten carbide, satellite alloy or other alloys for long-wearing.
