Do these proportioning may work in a different position to the horizontal?

The proportioning venturimétricos have to work horizontally, which is its normal position, not vertical or inclined.
In the case of the proportioning mod. SE-Z-ES and SE, the suction will be at the top while in the case where the mod. SE-PRO, the vacuum remains at the bottom.
