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 an excellent option for many commercial and light industrial applications, including directional flow control, handling of gas or liquid fuels, regulating fluids with suspended solids, such as slurries, or handling low-pressure, low-temperature services. Due to their smooth design, inline maintenance capabilities, leak-tight service, minimal resistance to flow, and multi-port design options, gas plug valves find application across a multitude of sectors and systems.
Whether it is gases, liquids, non-abrasive slurries, fuel gas piping systems, chemical industries, fly ash applications, or vacuum to high pressure applications, plug valves play a key role in an extensive range of applications and industries.
