FIG 1502 Manual Plug Valve 2 Inch For Industrial Applications

A plug valve controls the on-off status of pipelines by rotating a valve core (usually conical or cylindrical). The valve core is equipped with a through flow channel, and a 90° rotation can realize full opening or full closing.

Its core advantages include compact structure, small size, fast opening and closing speed, unobstructed flow channel and minimal flow resistance, making it suitable for conveying media containing suspended particles and with high viscosity.

Classified into soft-sealed plug valves and metal-sealed plug valves based on sealing types, the former has good sealing performance but limited temperature and pressure resistance, while the latter is suitable for high-temperature, high-pressure and highly corrosive working conditions.

This valve is widely used in industries such as oil and gas field development, oil refining, chemical engineering and metallurgy, especially for pipelines requiring fast opening and closing and frequent operation. It can also be used as a choke valve to achieve simple adjustment of fluid flow rate.
