How do rotary plug control valves work?
Rotary plug control valves work by rotating a cylindrical or tapered plug inside the valve body to regulate flow. As the plug turns, a port or passage within it aligns with the flow path, allowing precise control of fluid rate and pressure while maintaining tight shut-off and smooth operation.
Advantages of rotary plug control valves...
• Compact design with high flow capacity
• Precise throttling and control performance
• Tight shut-off reduces leakage and maintenance
• Smooth, low-friction operation extends lifespan
• Handles clean, dirty, or viscous fluids reliably
• Suitable for high-pressure and high-temperature use
