Didtek Oil Industry WCB Bolt Bonnet Gear Operated Top Entry Ball Valve
Application & Function:Didtek Cast Trunnion Ball Valve have been designed for severe oil and gas applications,including production,transportation and distribution.
Didtek Cast Trunnion Ball Valve designed the Side-Entry Trunnion-Mounted Ball Valves to assure bi-directional sealing of the valve with two independent floating seats. The design of these seats minimizes the torque required to operate the valve without losing the sealing power. This power is assured by zero differential pressure to the valve's maximum rated pressure. In addition, these repairable valves are manufactured to seal off both seats at the same time and to allow bleeding of the entrapped cavity pressure (DBB) with the ball in the closed position. The DBB feature allows for verifying that the seats are properly sealing. Technical SpecificationBrand: DIDTEK
