Case Study: Worm Gear Operated Ball Valve in Oil & Gas Pipeline

Project Background

In 2024, a Middle Eastern oil and gas company launched a pipeline expansion project to enhance natural gas transmission capacity. The system required high-pressure ball valves with reliable shutoff capability, easy maintenance, and long service life under harsh operating conditions. Safety was the top priority, as the valves would be used in critical sections of the pipeline.

Challenges

• Operating pressure up to 16 bar (PN16)

• Medium: Natural Gas & Crude Oil

• High risk of leakage and safety incidents if the valves failed

• Need for anti-static design and blow-out proof stem to ensure operational safety

Solution Provided

Our engineering team supplied the Q341F-16C Worm Gear Operated Ball Valve (DN150) for this project. Key features included:

• Full bore design for minimal flow resistance

• Carbon steel body (WCB) for strength and durability

• PTFE / RPTFE sealing ensuring excellent leak-tight performance

• Worm gear operation for precise control with low torque

• Anti-static structure and blow-out proof stem for maximum safety

• Flanged connection compatible with ANSI and DIN standards

Installation & Performance

The valves were installed in the main transmission line. During commissioning and operation, they demonstrated:

Reliable shutoff under fluctuating pressures
Smooth manual operation through the worm gear drive
Corrosion resistance even in a harsh desert environment
Low maintenance cost due to wear-resistant sealing materials

Customer Benefits

• Enhanced pipeline safety with secure sealing performance

• Improved operational efficiency by reducing manual effort

• Extended service life, lowering long-term replacement costs

• Compliance with international oil & gas standards

Conclusion

The successful application of the Q341F-16C Worm Gear Operated Ball Valve in this oil & gas project demonstrates its reliability in demanding industrial environments. It has become a preferred choice for clients requiring safe, durable, and cost-effective flow control solutions in energy infrastructure.
