Installation

3 Installation
If the valve and actuator are delivered sepa-
rately, first install the valve in the pipeline
and then mount the actuator.

3.1 Mounting position

4
Choose the place of installation where
the ambient temperature does not ex-
ceed or fall below the permissible limits
specified for the actuator and that allows
you to freely access the control valve
even after the entire plant has been com-
pleted.
4
Flush the pipeline thoroughly before in-
stallation.
4
Never install the valve with the actuator
suspended downwards.
4
Install a strainer (SAMSON Type 2 NI)
upstream of the control valve to prevent
any sealing parts, weld spatter or other
foreign matter carried along by the pro-
cess medium from impairing the proper
functioning of the valve, in particular, the
tight shut-off.
4
The valve must be installed free of stress.
If necessary, support the piping near the
connections.

3.2 Strainer

4
Install the strainer with the filter element
facing downwards upstream of the valve
inlet.
4
Choose the place of installation to allow
enough space to remove the filter.
4
Install the strainer with the flow direction
as indicated by the arrow on the body.

3.3 Additional installation
instructions
We recommend to install a hand-operated
shut-off valve both upstream of the strainer
and downstream of the control valve to be
able to shut down the plant for cleaning and
maintenance, and when the plant is not
used for longer periods of time.
