Frequently Asked Questions
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 by bearings, which absorbs line pressure and reduces torque. In contrast, a floating ball valve relies on line pressure to push the ball against the seat. Trunnion designs are better for high-pressure, large-diameter applications.
What are the advantages of a heavy-duty split body construction?
The split body design allows for easier assembly and maintenance of internal components like the ball and seats without special tools. The reinforced flanges and multi-bolt connections provide superior structural integrity for severe service.
When should a metal seated ball valve be used instead of a soft seated valve?
Metal seated valves are essential for high temperatures (above 200°C), abrasive media, or slurries that would degrade soft elastomeric seats. They provide a durable metal-to-metal seal in harsh environments.
How does the electric actuator integrate with automated control systems?
The actuator connects via standard signals (like 4-20mA or 24VDC) to DCS or PLC platforms. This allows for remote operation, real-time position feedback, and automated process sequences.
What do anti-static and fire-safe features mean for safety?
Anti-static design prevents spark ignition by dissipating static buildup. Fire-safe design ensures that the valve maintains sealing integrity even if soft seals are destroyed by fire, preventing catastrophic leaks in hazardous zones.
What industries typically use these electric trunnion ball valves?
They are widely used in oil and gas pipelines, LNG terminals, petrochemical plants, power generation, and mining, where high-pressure tolerance and remote automation are required.
