D971FThe electric clip type fluorine lined butterfly valve pn6 ~ PN16 (also known as corrosion resistant electric butterfly valve) is composed of electric actuator and fluorine lined butterfly valve body. Butterfly valve uses the butterfly plate with the valve stem rotating together as the opening and closing parts to realize the opening, closing and adjustment of the valve. The electric fluorine lined butterfly valve is a kind of high molecular material with thick lining technology on the flow passage parts, valve body, butterfly plate and valve stem, with excellent corrosion resistance. It can be applied to any concentration of acid, alkali, salt, oxidant, reducing agent, organic solvent and other media, It is an ideal product for intercepting and regulating the gas, liquid and semi fluid pipelines and vessels of chemical, petroleum, pharmaceutical, food, steel smelting, papermaking, hydropower and other systems, and can replace gate valves, globe valves and other types of cut-off and regulating valves.

1. Before installation, check whether the specification, pressure, temperature and corrosion resistance of butterfly valve meet the use requirements. Check whether the parts are damaged or loose.
2. The butterfly valve can be installed on the pipeline at any angle and should be closed; when welding the pipe flange, the valve sealing port should be blocked with a plate to prevent particles and sundries from damaging the sealing surface. After welding, take down the valve, clean the valve sealing surface and pipe cavity, and then install the fixed valve.
3. Please pay attention to the pressure bearing direction when the valve is closed.
4. Before installation, the sealing surface (sealing surface at both ends, sealing surface of butterfly plate and sealing surface of valve seat) shall be thoroughly cleaned to remove dust and dirt.
5. Before installation, the butterfly valve should be air tested, and the opening and closing position should be flexible, and the opening and closing position should be consistent with the position indicated by the pointer.
6. Manual operation, clockwise is off, counter clockwise is on, pointer indication is in place, it is not allowed to open and close the valve with additional force.
7. During the pressure test of the valve, it is not allowed to use single flange for installation and pressure test, but double flange installation and pressure test must be adopted. The test pressure shall comply with GB / T13927-92.
8. The bolts shall be tightened symmetrically and alternately instead of separately.
9. The limit screw has been adjusted before delivery, so it is not allowed to adjust it easily. Please refer to the manual for electric drive device.
10. When the electric butterfly valve leaves the factory, the opening and closing stroke of the control mechanism has been adjusted. In order to prevent the wrong direction when the power supply is connected, the user should first manually open it to the half open position before connecting the power for the first time, and then press the inching switch to check that the direction of the indicator wheel is consistent with the opening direction of the valve.
