2.2
Strainer
Install a strainer upstream of the regulator
(Fig. 3). Install the strainer with the direction
of flow matching the arrow on the body.
Make sure the filter element is vertically sus-
pended. Remember to leave enough space to
remove it.
2.3
Shut-off valve
Install a hand-operated shut-off valve both
upstream of the strainer and downstream of
the regulator (Fig. 3) to be able to shut down
the plant for cleaning and maintenance, and
when the plant is not used for longer periods
of time.
2.4
Pressure gauge
To monitor the pressures in the plant, install a
pressure gauge both upstream and down-
stream of the regulator (Fig. 3).
2.5
Control line
G ¼ tapped connection (9) at the actuator
housing. Install a control line with at least
6 mm inside diameter on site, preferably an
8 x 1 mm pipe made of steel or stainless steel.
Always attach the control line connection for
pressure tapping directly to the tank or vessel
as the medium is fully expanded and free of
turbulence at this point.
