See Fig. 1 on page 7.
Choose a place of installation that allows you
to freely access the regulator even after the
entire plant has been completed.
Î
Install the regulator free of stress. If nec-
essary, support the pipeline near to the
connecting flanges. Do not attach sup-
ports directly to the valve or actuator.
Î
Install a strainer (e.g. SAMSON
Type 2 N/2 NI) upstream of the regula-
tor to prevent any sealing parts, weld
spatter and other impurities carried
along by the process medium impairing
the proper functioning of the valve,
above all the tight shut-off.
4.1 Mounting position
The regulators are supplied ready for con-
nection.
Î
Install the regulator in a horizontal pipe-
line.
