Recently, a customer came to ask: Why do some butterfly valves need to be powered on to open when they have connected the pneumatic switch butterfly valve to air, and some butterfly valves can also be opened when they are powered off? Do you have similar problems? Today, while helping you answer this question, I also introduce some methods to improve the opening or closing speed of butterfly valves. 　　　　

When many people mention the valve, the first thing that pops up in their mind is of course some manual versions, because they may have seen such devices in some movie scenes or in some businesses. In fact, this is a very backward situation. Because many people know that electric butterfly valve belongs to electric regulation, that is to say, it really belongs to some high-tech products. It doesn't matter whether these devices are rubber sealed or metal sealed, because these butterfly valves are all controlled by power signals, that is, as long as there is a signal, they can be directly operated, which can directly promote production. This must save a lot of manpower and material resources, They are really great.
