A valve is a mechanical device that regulates or controls the flow of fluid (liquid or gas) by closing and opening or partially obstructing several entrances. Temperatures are also controlled through valves. Valves are commonly utilised in public locations to manage the water supply for domestic applications. However, valves are used in industries such as oil and gas, chemical, and others to conduct critical duties. Valve types used include ball valves, gate valves, butterfly valves, and globe valves.
