The pneumatic wafer soft seal butterfly valve is a common control valve for industrial automation pipeline, which adopts midline structure, wafer connection and pneumatic driving mode. The product supports multi-material and multi-sealing configuration, which can realize local and remote control and adapt to various industrial fluid transmission pipelines.

The main structure of the valve includes valve body, valve disc, valve stem, valve seat and pneumatic drive mechanism. The valve body can be made of cast iron, cast steel and stainless steel, and the valve seat is made of EPDM and PTFE, supporting disassembly and maintenance. Driven by compressed air, the equipment drives the butterfly plate to rotate 90°to complete the connection and disconnection of the pipeline. The valve positioner is installed to adjust the opening and closing angle and accurately control the pipe flow, pressure, liquid level and other parameters.

The valve is compatible with local control and remote centralized control, effectively improving the automation degree of the pipeline system. The product supports two-way sealing, with small structure area, strong flow capacity, diameter covering DN25-DN1000 and pressure rating up to 1.6MPa. It is applicable to clean fluid, viscous and particulate media, supports EX d Ⅱ BT4 and EX d Ⅱ CT6 explosion-proof standards, and is widely used in petroleum refining, chemical industry, electric power, environmental protection and other industries.

The pneumatic wafer soft seal butterfly valve is simple in installation, with stable sealing performance, strong automation adaptability, and can adapt to various complex industrial working conditions, with high safety factor. It is a common supporting valve for industrial automation pipeline system.
