Ball valve installation: It must be confirmed that the pipeline and valve have been cleaned before operation; the actuator operation of the valve drives the valve stem to complete rotation according to the size of the input signal: when it rotates 1/4 turn (900) in the forward direction, the valve is closed. When the reverse rotation is 1/4 turn (900), the valve opens; when the direction indicator arrow of the actuator is parallel to the pipeline, the valve opens; when the arrow is perpendicular to the pipeline, the valve closes.
Ball valve repair: a longer service life and maintenance-free time will depend on several factors: under normal working conditions, maintaining a harmonious temperature/pressure ratio, and reasonable corrosion data. Note: When the ball valve is closed, the fluid pressure in the valve body still exists; before maintenance, remove the pipeline pressure and leave the valve in the open position; before maintenance, disconnect the power or air source; before maintenance, disconnect the actuator from the bracket.
