INSTALLATION
? Vertical installation of horizontal piping or horizontal installation of vertical piping.
? When mounting the actuator in the fields, before installing the actuator, use an adjustable wrench tomanually rotate the valve stem several times. This rotation breaks the torque that may have built up during long-term storage.
? Pay attention to medium flow direction, make sure the valve to move in the proper direction, wire the input lines to the electric actuator correctly.
