Lubricated Plug Valves

Plug valves are among the earliest valve designs ever developed, with origins tracing back as far as ancient Rome. Today, they remain widely used across industries such as oil and gas, chemical and petrochemical processing, water and wastewater treatment, and pulp and paper manufacturing.

Their versatility makes them suitable for a broad range of applications, including oil and gas transmission lines, compressor stations, drain and vent service, blowdown systems, manifold isolation, and other demanding service conditions. Plug valves are most commonly used as quarter-turn valves for shutoff and on/off functions, though they can also be adapted for throttling or modulating service when required. Operation can be manual or automated with electric, pneumatic, or gas-over-oil actuators.

Thanks to their straightforward construction and minimal part count, plug valves deliver a compact design, reliable zero-leakage performance, long service life, and simplified maintenance.
