PRODUCT OVERVIEW
The electric fluorine lined single seat regulating valve is a bellows sealed single seat regulating valve. The contact part between the valve and the medium adopts high-pressure injection molding process. It is lined with strong corrosion resistant medium such as hydrofluoric acid and aging resistant polytetrafluoroethylene F46, and sealed with polytetrafluoroethylene bellows. It is equipped with (3810l / PSL Series) electronic electric actuator with power supply voltage (AC220V, 380V) Input the control signal (4-20madc or 1-5vdc) to control the valve opening to adjust the parameters such as pressure, flow, liquid level and temperature. It is widely used in the process control of strongly corrosive media such as acid and alkali, toxic and volatile gas and liquid media in various processes.
PERFORMANCE CHARACTERISTICS
1. Comply with GB / t4213-1992 American ANSI b16.104-1976 control valve leakage rate standard.
2. With strong corrosion resistance, the inner cavity of the valve body, valve core, valve seat and valve stem are lined with F46 with a thickness of 2.5 ~ 3mm.
3. Good sealing performance, double sealing with PTFE bellows and packing to ensure no leakage.
4. The leakage is very small. Because the valve core and valve seat are soft seals, the leakage is lower than class IV standard.
5. The regulation accuracy is accurate. 3810l series and PSL intelligent electric actuator are used to control the flow, with high accuracy and small error.
6. Explosion proof electric actuators can be selected for flammable and explosive special occasions to ensure safe use.
