The 6310 1/4-1/4 mechanical ball valve with temperature ratings of -20°C to 80°C and a nickel plated brass material construction is manufactured by PNEUMAT SYSTEM. This part has a two-way function, with the ability to stop or control the flow of gases, liquids or semi-liquids with a quarter inch (1/4) connection on both the inlet and the outlet sides. The mechanical ball valve is comprised of a ball-shaped disc, with a hole in it, that is connected to a handle. When the handle is in the open position, the hole in the disc is in line with the internal passageway, allowing flow through the valve. When the handle is in the closed position, the hole in the disc is positioned perpendicular to the internal passageway, which blocks the flow through the valve.
