• Based on technical upgrades of the dedicated gas fixed ball valve, designed with the concept of achieving a service life synchronized with metal pipelines, the external structure adopts an overall welding technology with pressure vessel-style design. It features a bolted flange-free structure, completely eliminating the leakage risks associated with static sealing of flanges. This design offers high sealing performance, maintenance-free operation, and a long service life.

Purpose

Particularly suitable for various long-distance, medium to high-pressure gas transmission pipeline applications.
