What is a lift plug valve?

Lift plug valves are designed to operate in severe applications that include high temperatures, fluids, and solids in suspension.

What does a plug valve do?

If a sector relies on hydraulic systems for operation, you can guarantee that plug valves are an essential component in use. Plug valves are quarter-turn manual motion valves that stop or start fluid flow. 

When would you use a plug valve?

Plug valves are commonly used in low-pressure-low-temperature services as they are high-capacity valves that can be used for directional flow control, even in moderate vacuum systems. 

How does a plug valve seal?

A plug valve seals using the mechanism that rotates between the open and closed positions and protects both seals from the flow path.
