Pneumatic Diaphragm Control Valves Used In Petroleum Chemical Power Industries

This is a pneumatic diaphragm-type cast steel control valve, belonging to the category of industrial valve equipment.

Made of cast steel (marked "WCB"), this control valve boasts excellent strength and resistance to temperature and pressure, making it suitable for pipeline systems in industries such as petroleum, chemical, and power. It is used for precise regulation of fluid flow, pressure, and other parameters. The valve is equipped with a blue pneumatic diaphragm actuator at the top, which uses air to drive the valve disc, thereby precisely controlling the flow rate of the medium. It is also equipped with accessories such as a positioner to achieve automated, high-precision regulation.

• Pneumatic actuator (orange upper part): Driven by air pressure to move the valve, serving as the power source.
• Control valve body (silver valve body): In contact with the fluid, changes flow area through valve core movement to achieve regulation.
• Accessories (blue, white parts): Including filter pressure reducing valve to purify and adjust air source pressure; positioner receives control signals to precisely control valve opening.

Core function: Receives control system signals to automatically adjust fluid parameters in pipelines, ensuring stable, efficient and safe production processes such as maintaining chemical reaction temperatures within required parameters.
