The control valve is also called control valve. It is a device in the process control system that changes the medium flow rate by power operation. It includes a valve component. There is a component that changes the process fluid rate inside. The valve component is connected with the actuator, which is used to respond to the signal sent by the control element to achieve the purpose of regulating the flow rate.

Basic structure of fluorine lined regulating valve

1. Fluoroplastic fully lined regulating valves include Zha/b pneumatic membrane straight through single seat regulating valve and Zaza/b electric straight through single seat regulating valve series. The valve body cavity and valve components in contact with materials are fully lined with Fluoroplastic (F4/F46/PFA). Its structure is safe and reliable, and it is suitable for highly corrosive, highly toxic and volatile media. It is widely used in pipeline automation systems of petroleum, chemical industry and metallurgy.

2. The valve disc and the valve stem are designed as an integrated structure to prevent the possibility of the inner parts rushing out of the valve body due to the pressure fluctuation of the pipeline. The structure is compact and the use is safe and reliable.
