The circular closing function of ball valves is located in the seat within the valve. Inside the valve, this design allows for continuous sealing stress. The ball-closing device, which spins to open and close the valve, is known as a ball valve. Ball valves are an excellent alternative when a tight seal is required when the valve is closed due to even sealing stress. They can even move solid, liquid, and gaseous material as well as fluids in all three states.
