Product Overview
Neway cryogenic floating ball valves works down to -196°C, with application covering LNG, LPG, air separation,etc. It enjoys state of-art technology, lipseal, to keep the excellent sealing in ultra-low temperature. On-line maintenance available for the top entry.
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
