Description
Trunnion Mounted Ball Valve (API 6D) Manufacturer & Exporter in India
FlowBiz Exports manufactures heavy-duty Trunnion Mounted Ball Valves engineered specifically to meet the rigorous demands of API 6D standards for critical pipeline transmission and severe industrial service. Unlike standard floating ball valves, the ball in a trunnion-mounted design is anchored at the top and bottom by bearings, allowing smooth operation, reduced operating torque, and dependable sealing under high pressure and large-bore applications.
Key Performance Features
- Double Block and Bleed (DBB): Provides positive shut-off on both seats simultaneously while allowing the cavity between seats to be safely drained or vented.
- Low Operating Torque: Trunnion support bearings absorb the load generated by line pressure, ensuring easy operation even in high-pressure differential conditions.
- Emergency Sealant Injection: Equipped with sealant injection fittings on both stem and seats for fast restoration of tight sealing in case of seat damage.
- Spring-Loaded Seats: Floating seat rings are pre-loaded with springs to maintain constant contact with the ball, delivering reliable bi-directional tight shut-off at both low and high pressure.
