Frequently Asked Questions
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, providing reliable performance under all conditions.
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, lowers downtime, and cuts operational costs.
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 and high-pressure industrial applications.
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 their superior corrosion resistance. These materials make the valve suitable for oil & gas, chemical processing, and other harsh industrial environments.
The trunnion ball valve is available in sizes ranging from 2" to 64", covering a wide range of pipeline requirements. Whether for small-scale installations or large industrial pipelines, there is a suitable size available to meet specific flow and pressure requirements.
The emergency shutoff feature includes a dedicated sealing device that activates during critical situations such as actuator failure or extreme pressure events. It ensures the valve can achieve a tight, leak-free seal immediately, protecting pipelines, personnel, and the environment from potential hazards.
