Mainly suitable for cutting off or connecting pipeline media in various systems of thermal power plants. Applicable media: non corrosive media such as water and steam. The characteristics of forged steel valves compared to other valve products are high temperature and high pressure, unique self sealing design, and the higher the pressure, the more reliable the seal. Due to its unique performance, technical characteristics, and working conditions, the product has also developed unique features that cannot be replaced by other products.
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. It can meet the complex working conditions such as high pressure, high temperature, corrosive media, and frequent operations.
The Rotary Ball Valve adopts advanced ball rotation sealing technology and is specially designed for harsh working conditions. It is suitable for the control of high-pressure, high-temperature and corrosive media in industries such as petroleum, chemical engineering, natural gas, and power. Its unique rotating valve seat structure effectively reduces friction and wear, ensuring more durable sealing performance and easier operation. The valve body is made of high-quality stainless steel, carbon steel or special alloy materials, and is precisely processed and hardened to ensure long-term stable operation. It supports various driving methods such as manual, pneumatic, and electric, meeting different automation requirements and is an ideal choice for industrial pipeline fluid control.
