What are Dual Expanding Plug Valves

The double expansion plug valve is a non-lubricated, resilient-sealing, plug valve that has a mechanical means of releasing the plug before rotating from the closed to the open position.
When the valve is opened, the plug rises, thereby retracting back into the seat section or sliding through the tapered dovetail connection. The plug rotates to the open position only after the carriage has been fully retracted from the valve seat.
Conversely, when the valve is closed, the valve plug and cavity are free to rotate until the cavity is above the port and the seal is in contact with the valve body.
The plug is then pushed down between the cavity and the tapered surface, wedging out the cavity to achieve positive upstream and downstream closure.

We focus on valves in standard and special materials as customer request.
