A manual control valve with a hand wheel regulates the flow of liquids in industrial piping systems by turning a wheel. Commonly found on gate, globe, and diaphragm valves, the hand wheel offers flow control and is suited for high-pressure applications where gradual opening or closing reduces risk. These valves are vital for system isolation and process control, enabling safe shutdown for maintenance or emergencies.
