Product Description
A plug valve is based on a plug with a hollow passage in the valve body. The quarter-turn motion creates an alignment between the pipe and the hole, leading to an open state. When turned to a 90-degree angle from the open position, the valve sits across the pipe leading to a closed state.
Plug valves are available in a variety of different styles and port openings through the plug.
- Two-Way Plug Valves: The design allows for a closure element in the middle (a plug and a sleeve), along with a straight through, two-way service for the open and close function.
- Three-Way Plug Valves: These valves include a third port, which typically sits at a right angle from the inlet. These plug valves can help in diverting flow (entry from inlet directed between one or both outlets) or combining flow (entry from the two inlets channeled into a single outlet).
