Q741F Hydraulically Actuated Ball Valves

High-performance integrated ball valve solutions based on T and S series actuators for reliable isolation in shipboard and 50m submerged environments

The Q741F Series is INJOY’s premier solution for high-pressure automated isolation. By integrating zero-leakage ball valves with our modular hydraulic actuators, we provide a complete, factory-tested package. This series eliminates the complexity of separate sourcing, ensuring perfect alignment between the drive system and the valve body for critical shut-off tasks.
