Frequently Asked Questions

Q What is a trunnion mounted ball valve and how does it differ from a floating ball valve?

A trunnion mounted ball valve has the ball mechanically anchored at the top and bottom by trunnion supports, which absorb line pressure and significantly reduce operating torque. In contrast, a floating ball valve relies on line pressure to push the ball against the downstream seat. Trunnion designs are preferred for larger diameters and higher pressure applications.

Q What are the advantages of a split body construction in ball valves?

The split body construction allows the valve to be assembled and disassembled without removing it from the pipeline, making in-line maintenance much easier. The multi-bolt design with reinforced flanges also provides superior structural integrity for severe service conditions.

Q In what applications is metal seated sealing most suitable?

Metal seated sealing is best suited for extreme service conditions including high-temperature steam lines, high-pressure pipelines, slurry or abrasive media, and processes with particle-laden fluids where soft seats would fail.

Q How does the electric actuator integrate with automated control systems?

The top-mounted electric actuator is designed with standard control interfaces, allowing direct integration with SCADA, DCS, or PLC-based automation systems. It supports remote on/off switching and position feedback.

Q What do anti-static and fire-safe features mean for valve safety?

Anti-static features prevent electrostatic charge buildup, critical in explosive environments. Fire-safe design ensures the valve retains sealing capability during a fire, even if soft materials are damaged, reducing risk of escalation.

Q What industries commonly use these valves?

These valves are widely used in oil and gas transmission, petrochemical refineries, power generation, subsea applications, LNG terminals, and industrial water treatment facilities where reliability is essential.
