Trunnion Ball Valve
Side-entry ball valves are manufactured in accordance with API 6D standards. The complete range of forged valves is designed in two or three bolted pieces with a solid double trunnion configuration and two independent seats for an easy bidirectional sealing, to ensure the greatest level of tightness and reliability under high pressure and temperature conditions in all critical isolation services.
Materials selection is fully customizable to meet the customer's project specifications and several unique features are available to offer an enhanced technical solution suitable to aggressive offshore environments and corrosive and abrasive fluids.
