Pneumatic film lined plastic bellows regulating valve is the executive unit in the automation instrument system. It is installed on the medium delivery pipeline and used in conjunction with other instruments to control parameters such as flow. In addition to reliable sealing, it is also resistant to strong corrosive media such as acid (hydrochloric acid, sulfuric acid, hydrofluoric acid) and alkali. It is suitable for regulating highly toxic, precious, volatile, and permeable media. Therefore, it is widely used in chemical, petroleum, metallurgy, medicine, light textile and other industrial automation devices to adjust the flow.
