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 features upper and lower trunnion bearings that fix the ball in place, absorbing pipeline pressure and reducing operating torque. Unlike floating ball valves where the ball shifts under pressure to seal, the trunnion design is ideal for high-pressure, large-diameter applications requiring stable and consistent performance.

What are the advantages of a heavy-duty split body construction?

The split body design uses multiple bolts and reinforced flanges to deliver superior structural strength and pressure resistance. It also simplifies maintenance — the valve internals can be accessed and serviced without removing the entire body from the pipeline, reducing downtime in severe service environments.

In which applications is a metal seated sealing structure recommended?

Metal seated sealing structures are recommended for applications involving high temperatures, high pressures, abrasive media, or fluids containing solid particles — such as steam lines, slurry systems, petrochemical processing, and power generation. Metal-to-metal contact ensures reliable shut-off where soft seats would degrade or fail.

How does the electric actuator integrate with automated control systems?

The top-mounted electric actuator supports standard control signal interfaces (e.g., 4–20mA, on/off signals), allowing seamless integration with DCS, PLC, or SCADA systems. This enables remote operation, real-time valve position feedback, and automated open/close control without manual intervention.

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

Anti-static design includes grounding paths between the ball, stem, and body to dissipate static electricity buildup — critical for flammable or explosive media. Fire-safe design ensures the valve maintains a reliable seal even if the primary soft seat is damaged by fire, preventing uncontrolled leakage and meeting international standards such as API 607 or ISO 10497.

What maintenance is required for a trunnion mounted ball valve with metal seating?

Routine maintenance includes periodic inspection of the seat and ball surfaces for wear or erosion, checking actuator function and electrical connections, verifying stem packing integrity to prevent leakage, and lubricating bearing surfaces as specified. The split body construction facilitates easy internal access, reducing maintenance complexity and service time.
