Design Features
• Spring-preloaded seat structure is designed to effectively avoid conflict
between sealing and torque
• Hole drilling on yoke or stem, to keep connection between stem extension and cavity to achieve pressure relief of cavity
• Hole drilling on the ball’s upstream side, to achieve pressure relief of
cavity
• Fire-safe & anti-static design
• High quality PCTFE, which has excellent stability in low temperature, or other high-strength seat, is chosen as seat material
• On-line maintenance can be achieved in top-entry series
