Which valve is described as being like a cork in a bottle?

Explanation:
This describes a plug valve. The main element is a cylindrical plug that fits tightly inside the valve body and sits on seats. It has a bore to pass fluid when aligned with the ports, but when you rotate the plug so the solid part blocks the bore, it seals off the passage just like a cork in a bottle. That simple, solid-stopper action is what gives the cork-like impression. Other valve types use different mechanisms—a globe valve slides a disk to regulate flow, a ball valve uses a spherical ball with a bore, and a butterfly valve rotates a disk to open or close—but none rely on a single solid stopper filling the passage the way a cork does.
