Design and principle of operation

Pressure gauges
Install a pressure gauge (3 and 5) at suitable
points to monitor the pressures prevailing in
the plant.
Bypass and shut-off valves
We recommend installing a shut-off valve (1
and 6) both upstream of the strainer and
downstream of the regulator and installing a
bypass line. The bypass ensures that the
plant does not need to be shut down for ser-
vice and repair work on the regulator.
