The inner part of Dongfeng electric butterfly valve is filled with inert gas, and the product with elastic function is produced by the piston. The product works without external power, with stable lifting force, and can stretch freely (the lockable air butterfly valve can be positioned at will). It is widely used, but the following points should be noted during installation:
1. The air butterfly valve is a high-pressure product, which is strictly and randomly analyzed, baked and bumped.
2. The piston rod of the air butterfly valve rotates tightly to the left. If you need to adjust the valve direction, you can only turn it to the right.
3. Operating ambient temperature: - 35 ℃ -+70 ℃. (. Custom made 80 ℃)
4. When installing the connection point, it should rotate flexibly without jamming.
5. The size should be reasonable, the force should be appropriate, and the stroke size of the piston rod should have an 8mm margin.
6. Do not use electric butterfly valve beyond the recommended safe extension height
7. In order to extend the service life of the electric butterfly valve, please do not use the electric butterfly valve below. low compression height
8. Do not use the electric butterfly valve under the pressure of more than 0.7Mpa
9. Do not use the electric butterfly valve in a twisted state
