Plug valves are high capacity valves that can be used for directional flow control, even in moderate vacuum systems.

Do plug valves have a flow direction?

Plug valves are high capacity valves that can be used for directional flow control, even in moderate vacuum systems.

How does a plug valve seal?

The plug valve uses a mechanism that rotates between the open and closed position and protects both seals from the flow path. During rotation there is no contact between body and seals, and slips expand onto the body seat when the valve is closed to avoid causing any wear or abrasion to the seals.
