Certified fire safe design with 100% pass rate on fire tests. Dual sealing system with O-ring seals and metal graphite spiral wound gaskets ensures continued operation during fire conditions. Complies with API 607, API 6FA, BS 6755, and JB/T 6899 standards.

When closed, each seat independently seals process medium between upstream/downstream and body cavity, allowing safe bleeding of trapped cavity pressure through drain and vent valves.

Double piston effect seat design creates resultant thrust pushing seat ring against ball, requiring cavity pressure relief to prevent overpressure buildup.

Separate stem from ball with integral T-type round shoulder retained by gland, with alternative designs available upon request.

Spring plus graphite anti-static device maintains electrical continuity between all metallic components, ensuring resistance meets severe service requirements.

Standard on DN150 (NPS 6) and larger valves, optional on smaller sizes. Provides emergency sealing capability if O-rings are damaged.

Ball fixed by trunnion and stem for sizes 4" and smaller. Trunnion plate support for sizes 6" and larger.
