3/4 Inch Plug Valve

A 3/4 Inch Plug Valve, roughly equivalent to DN20, is a type of quarter-turn rotation valve used to control fluid flow in pipelines. It consists of a cylindrical or conical plug with a passage that aligns with the pipeline for unrestricted flow when open. Rotating the plug 90 degrees shuts off flow by closing the passage tightly against the valve body, making it suitable for applications requiring quick on/off operation and minimal fluid resistance.
