What is a plug valve?

The plug valve is a fitting that is comparable to a ball valve. However, the plug valve does not have a spherical but a conical shut-off body. Like the ball valve, it is used to shut off pipes. The plug valve seals by pressing the contact surface against the housing. This means there is no gap between the shut-off body and the gasket where particles can penetrate or deposits can form. Plug valves are therefore particularly suitable for media containing solids.
