Flanged plug valves are designed with a cylindrical body and a tapered plug that rotates within the valve. They are widely used in pipelines due to their simplicity, durability, and low maintenance requirements. The flanged design allows for easy integration into existing systems, making them a preferred choice in industries such as oil and gas, water treatment, and chemical processing.

• High pressure rating up to 2000 SI. • Corrosionresistant materials for longlasting performance. • Smooth operation with minimal friction. • Versatile applications in various fluid systems.
roper installation is critical to ensure the longevity and efficiency of flanged plug valves. Below are the stepbystep installation procedures:
Before installing a flanged plug valve, inspect the valve for any damage or wear. Verify that all components, including the plug, stem, and body, are in good condition. Ensure the pipeline is clean and free of debris to prevent contamination.
lace the flanged plug valve in the desired location within the pipeline. Ensure it is aligned with the flange connections on both sides. Use a torque wrench to tighten the bolts evenly, maintaining the correct flange gap (typically 0.016 inches).
Apply a highquality lubricant to the plug and stem to ensure smooth operation. Avoid using petroleumbased lubricants, as they may degrade the valve materials over time.
After installation, perform a pressure test to verify the valve’s integrity. Gradually increase the pressure and monitor for leaks or abnormal noises. Once the test is successful, the valve is ready for operation.
How to avoid alignment issues during installation? roperly aligning the flanges is crucial. Use a straightedge to check for misalignment and adjust as needed. Additionally, ensure the pipeline is properly supported to prevent stress on the valve.
Regular maintenance is essential to extend the lifespan of flanged plug valves. Here’s what you need to know:
Inspect the valve monthly for signs of wear, corrosion, or leaks. ay special attention to the plug and stem, as these are the most critical components.
Remove any debris or buildup from the valve using a soft brush or compressed air. Avoid harsh chemicals that may damage the valve surface.
Reapply lubricant to the plug and stem annually to ensure smooth operation. Use a lubricant compatible with the valve materials.
Conduct pressure checks biannually to ensure the valve is holding up under operational conditions. Replace any damaged parts immediately.
What to do if the valve is leaking? Leaks may occur due to loose bolts or damaged seals. Tighten the bolts or replace the seals as needed. If the issue persists, consult a professional technician.
