Mounting orientation:
It is recommended that the valves be mounted
upright in an easily accessible location. When
mounted horizontally, the yoke should be fitted
such that the stanchions are positioned vertically,
one above the other
For the flow direction the following is valid:
Valve plug close-off movement must always be
directed against flow. This requirement is fulfilled
if the valve is installed in arrow-direction. (See
symbols on valve body)
