Look literally can explain ah, pro! Check valve, your fluid medium can come in and want to go back. No way！ Blocked. SO just goes back! This valve switch is usually dependent on the medium itself. What about the stop valve?. The flow of water in your pipe is good, I said, stop (if it is an electric globe valve) press the Shimonoseki button. Stop and stop right now. Medium can not flow. I want to open. Press open. The stem is lifted and the medium will flow! Of course inside the internal structure will not give you too much!
Stop valve has a handwheel, the general check valve by gravity or spring action, there is no operating mechanism, but the large check valve is there.
