Make sure during piping that the arrow direction of the valve body is aligned with the flow direction of the fluid. . Do not use the valve in a line where the fluid flow is very turbulent. Oscillation of the ball may occur in the valve, causing breakage. . Near pumps with unstable flow, use AV swing check valves.
