Plug Valves

DBB Plug Valve

The DBB Plug Valve is a high-performance fluid control device. It adopts advanced track-guided technology to achieve low-torque opening and closing and zero-leakage sealing. This valve is specially designed for harsh working conditions and is suitable for key fields such as petroleum, chemical industry, power, ships, and long-distance pipelines. It can meet the complex working conditions such as high pressure, high temperature, corrosive media, and frequent operations. (also known as the general valve) is a high-performance fluid control device. It adopts advanced track-guided technology to achieve low-torque opening and closing and zero-leakage sealing. This valve is specially designed for harsh working conditions and is suitable for key fields such as petroleum, chemical industry, power, ships, and long-distance pipelines.
