Plug Valve

The valve of a plug valve is a cylindrical rotating body that regulates the flow of fluid through rotation. There is usually a V-shaped channel on the circumferential surface of the valve. When the valve rotates, the opening of the V-shaped channel can be aligned or misaligned with the fluid channel to regulate flow. When the valve is fully closed, both sides of the V-shaped channel are completely isolated from the fluid channel, achieving complete closure.
