Installation position

With regard to the installation position, pay attention to the flow direction arrow. When installing the valve
in a horizontal pipeline, a vertical position of the spindle is recommended with the hand wheel at the top or
an inclination of up to 65° from the vertical.
5.2 Notes regarding the installation
