Plug Valve Solutions for Industrial Flow Control
API 6D Certified | Designed for Corrosive & High-Pressure Applications
Professional-grade plug valves engineered for demanding industrial environments. Our lubricated and non-lubricated designs deliver reliable flow control with minimal maintenance requirements.
What Is a Plug Valve?
Understanding the Working Principle & Applications
A plug valve is a quarter-turn rotary valve that uses a tapered or cylindrical plug to control fluid flow. The plug has a port through its center that aligns with the pipeline when open, providing straight-through flow. When rotated 90 degrees, the solid portion blocks flow completely, making it ideal for isolation applications.
-
Fast Quarter-Turn Operation
Quick 90° rotation for rapid opening and closing, ideal for emergency shut-off applications.
-
Simple Structure, Low Maintenance
Fewer moving parts compared to gate valves, resulting in reduced maintenance requirements and longer service life.
-
Bi-Directional Flow Capacity
Handles flow in both directions with equal efficiency, providing design flexibility in piping systems.
