Is the valve generally opened or closed when turned clockwise?

[OLola]

Generally, turning the valve clockwise closes it, while turning it counterclockwise opens it. Valves are pipeline accessories used to open or close pipelines, control flow direction, and regulate and control the parameters of the conveyed medium. Based on their functions, they can be categorized into shut-off valves, check valves, regulating valves, etc. They serve purposes such as shutting off, regulating, diverting flow, preventing backflow, stabilizing pressure, diverting, or relieving pressure. Valves can be used to control the flow of various types of fluids, including air, water, steam, various corrosive media, slurry, oil products, liquid metals, and radioactive media. Since selecting the most suitable valve for a pipeline system is crucial, understanding the characteristics of valves and the steps and basis for selecting them becomes equally important. The final control element in a pipeline is the valve.
