Frequently Asked Questions

What is dual-drive operation in a trunnion ball valve?
Dual-drive operation means the valve is equipped with both an electric actuator for automated control and a worm gear for manual operation. This ensures the valve remains controllable even during power failures or emergencies.
What are the benefits of a top entry design?
The top entry design allows operators to access the valve's internal components—including the ball, seats, and stem—from the top without removing the valve from the pipeline. This significantly reduces maintenance time and costs.
Why is a trunnion-mounted ball preferred for high-pressure applications?
In a trunnion-mounted ball valve, the ball is mechanically anchored at both the top and bottom, preventing it from shifting under high pressure. This ensures stable pressure distribution across the seat seals, making it ideal for large-diameter pipelines.
What materials are available for corrosive environments?
The valve is available in a range of materials including ASTM A216 WCB (carbon steel), Stainless Steel (304/316), and Duplex Stainless Steel, each selected for superior corrosion resistance in oil & gas or chemical processing.
What size range is available for this trunnion ball valve?
The trunnion ball valve is available in sizes ranging from 2" to 64", covering a wide range of pipeline requirements for both small-scale and large industrial installations.
How does the emergency shutoff feature work?
The emergency shutoff feature includes a dedicated sealing device that activates during critical situations. It ensures the valve can achieve a tight, leak-free seal immediately, protecting personnel and the environment.
