MG = diaphragm size
The normal operating pressure in the plant should be as close as possible to the lower area of the
operating range of the pulsation damper.

The Kv values cannot be specified as with GEMÜ diaphragm valves. The basis of the Kv values is
piping of the relevant standard of the connection type. In general, the Kv values are up to 10% less
than those of comparable piping due to flow turbulences in the seat area.
