The following is valid for the flow direction:
Valve plug close-off movement must always be
directed against the flow. This requirement is
fulfilled if the valve is installed as directed by the
arrow on the valve body.

Note:
L
With mixing valves, the through flow should be
used for regulating and with diverting valves, the
bypass flow should be used (equal percent).
