What does Daxing electric explosion-proof plastic butterfly valve mean by passive feedback electric butterfly valve? The inner ball of the pneumatic ball valve of the elastic ball valve itself is elastic, and the valve seat used inside the ball valve is also elastic metal material, so the material density is higher, and the compression resistance is stronger. When the pressure of itself does not reach a certain strength, it must be operated by external forces to increase a force to improve the internal sealing of the machine, Such pneumatic ball valves are usually used under the production conditions of high temperature and pressure.
、 Fourth, if the pneumatic butterfly valve is not used for a long time, many stains will accumulate on the surface. Therefore, it is necessary to remove the stains on the surface to maintain the cleanliness of the surface and will not be affected. Then put the valves indoors in order. Of course, you need to put the valves indoors in a well ventilated and dry place. It cannot be stacked or placed in the open air. Every detail should be very careful during maintenance. No error is allowed. Once a problem occurs, it will affect the use of the valve and the processing progress.
