A butterfly control valve is a type of quarter-turn valve that is commonly used for isolating or regulating fluid flow. It features a disk-shaped closing mechanism that rotates within the pipe. The operation is similar to a ball valve, allowing for quick shut-off. Butterfly valves are popular due to their cost-effectiveness, lightweight design, and ease of installation, which reduces the need for heavy support structures.
The disc is positioned in the center of the pipe and is connected to an actuator. When the actuator turns, it moves the disc either parallel or perpendicular to the flow direction. Unlike ball valves, the disc remains in the flow path at all times, which causes a pressure drop regardless of the valve position.
The ZSHWB Series of Double Eccentric Butterfly Valves is known for its high performance. Both the valve disc and sealing ring are designed with a special eccentric structure, offering excellent shut-off performance, easy maintenance, and long service life. These valves can be used for both regulation and shut-off functions, making them ideal for applications in industries such as metallurgy, oil, chemical engineering, power generation, and natural gas processing.

Pressure reducing valve can automatically reduce the high-pressure input to a stable low-pressure output, and is not affected by the flow rate or input pressure changes. The output pressure is maintained within a preset range through a precise pressure regulating pilot. When the output pressure exceeds the set range of the pressure reducing valve, the pressure reducing pilot and the main valve will automatically close to form a tight seal.
If the optional check feature is selected, when the reverse pressure is generated, the backflow fluid will enter the upper chamber, closing the valve and preventing the flow back
