Electric fluorine lined regulating valve
Detailed technical analysis of electric fluorine lined regulating valve:
1、 Core Definition and Structure
Electric fluorine lined regulating valve is an industrial valve driven by an electric actuator and lined with fluoroplastic in the valve body, specifically designed for flow control of highly corrosive media. Its core structure includes:
Fluorine lined valve body: The valve body, valve core and other overcurrent components are lined with 2-5mm thick fluoroplastic (PTFE/F46/PFA), which can withstand strong corrosive media such as 98% concentrated sulfuric acid and hydrofluoric acid.
Electric actuator: Supports remote control with 4-20mA signal, response time ≤ 0.5 seconds, compatible with DN15-300 diameter.
Double sealing system: bellows+packing combination seal, with a leakage rate lower than the national level IV standard (≤ 10 ⁻⁶ Pa · m3/s).
