Class150~Class2500 PN16~PN160 pipelines, used to hydrogen sulfide medium, impurities, serious corrosion of

natural gas long-distance pipeline.

Trunnion Mounted Ball Valve Content

Design Feature

Upstream Seal Two-way Valve,Fire-Safe Design API 607/API 6FA

Stem and Seat Emergency Sealing

The seat ring and the valve stem have a special grease injection valve. In case of the leakage,

the grease will be injected to the valve ball surface and stem room to create a temporary sealing.

Double Block and Bleed

The trapped cavity pressure can bleed out by vent fitting or drain plug when the valve is in

fully open or fully closed position. The fluid is intercepted by seats of up and down stream

side. So the stem packing or O-ring may be replaced under working pressure. Each seat works

independently assuring tight seal against ball on both upstream and downstream side.
