What is this valve in the pipeline next to the accelerator of Buick New Yinglang? I accidentally moved it. How to adjust this valve clockwise or counterclockwise?

Tap water valves are generally divided into two types, one is a ball valve; One is the gate valve. The wrench of the ball valve is closed when it is perpendicular to the water pipe, and it is open when it is twisted 90 degrees forward or backward with the water pipe; The handwheel of the gate valve rotates clockwise to close and counterclockwise to open. The gate valve should not be screwed too tightly when in use, so as to avoid the thread pre-buckle valve core falling off. Ball valve is labor-saving and durable in application.
