Installation position

≤ DN150
With regard to the installation position, pay attention to the arrow showing the flow direction. When
mounting the valve in a horizontal pipeline, a vertical position of the obturator is recommended (cover
facing upwards) or an inclination of up to 65° from the vertical.
