Application & Fonction:
KOZO Cast Fixed Ball Valve have been designed for severe oil and gas applications, including production, transportation and distribution.
KOZO Cast Fixed Ball Valve designed the Side-Entry Fixed 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.
