Installing The Valve; Additional Installation Instruc- Tions; Installing The Temperature Sensor - Samson 43 Series Mounting And Operating Instructions

Installation
2. Installation
On installing the regulator, make sure that
the permissible ambient temperature does
not exceed 80 °C.

2.1 Installing the valve

The valve may be installed in any desired
position, however, we recommend that the
valve be installed in a horizontal pipeline
with the thermostat vertically suspended.
The medium must flow through the valve in
direction indicated by the arrow on the
valve body.
2.1.1 Strainer
A strainer (SAMSON Type 1 NI) must be in-
stalled upstream of the relevant valve, since
sealing particles, globules or other im-
purities carried along by the process me-
dium could impair the proper functioning of
the valve, especially tight shut-off.
The filter element must be vertically sus-
pended.

Ensure that ample space is available to
remove the filter.
2.1.2 Additional installation instruc-
tions
Ideally, hand-operated shut-off valves
should be installed both upstream of the
strainer and downstream of the regulator.
This allows the plant to be shut down for
cleaning and maintenance routines, or
when the plant is not operated for extended
periods.
To check the adjusted set point, we rec-
ommed that a thermometer be installed
near the sensor immersed in the medium to
be controlled.

2.2 Installing the temperature sensor

The temperature sensor may be installed in
any desired position. Its entire length must
be immersed in the medium to be control-
led.
When choosing the point of installation,
make sure that the sensor is installed in a lo-
