C700 Series Single Seated Control Valve is a top-guided structure control valve, used in equipment that can achieve air opening or air closing. The fluid channel of the valve body is in an S-shaped streamlined shape, featuring low pressure drop loss, large flow rate, wide adjustable range, high accuracy of the flow characteristic curve, large guiding area of the valve core, and good vibration resistance. The control valve is equipped with a multi-spring diaphragm actuator, which features a compact structure and large output force. It can be used to control various fluids with different pressures and temperatures.
The C-type wear-resistant ball valve is a valve designed specifically for harsh working conditions, characterized by its eccentric ball setting and "C" - shaped channel. This design cleverly utilizes the translational characteristics of the sphere during rotation, achieving a "wedging" effect with the valve seat, thereby significantly improving the sealing performance. In addition, its ingenious upper and lower support axis positioning structure not only ensures the stability of the sphere, but also avoids tilting, allowing the medium thrust to be evenly dispersed, thereby extending its service life. This design not only optimizes the sealing performance, but also reduces the opening and closing torque and improves the opening and closing efficiency. Widely used in industries such as coal chemical, petrochemical, offshore platforms, LNG, etc.
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 and long-distance pipelines. It can meet the complex working conditions such as high pressure, high temperature, corrosive media, and frequent operations.
