Swagelok Fast Loop Module, Руководство пользователя, Страница: 12 / 56

Installation
1/4 inch and 1/2 inch systems have
fractional Swagelok tube fittings or metric
Swagelok tube fittings for the system
connections.
Note: For 1/4 in. systems, all inlet and
outlet connections are 1/4 in. or 6 mm
with the exception of the sample to
analyzer connection, which is 1/8 in.
or 3 mm.
Note: For 1/2 in. systems, the fast loop out,
fast loop in, relief outlet, oily drain
(bottom right), and grab sample outlet
connections are 1/2 in. or 12 mm;
return from analyzer, purge in, and
oily drain (center right) connections
are 1/4 in. or 6 mm; sample to
analyzer connection is 1/8 in. or
3 mm.
Note: All internal fittings (non-system
connections) are fractional fittings.
Install Swagelok tube fitting according to
the
Swagelok Tube Fitting Instructions for
1 in. (25 mm) and smaller fittings , page 24.
Inlet Connections
1. Fast Loop In - connect to the sample
transport line to be analyzed.
2. Sample to Analyzer - connect to the
remainder of the sample conditioning
system prior to the analyzer.
3. Return from Analyzer (option) - connect
to the outlet line from the analyzer.
There must be sufficient pressure to
create flow back into the FLM return.
4. Purge In (option) - connect to a purge
line. It will be used to purge the sample
side of the system prior to servicing.
Configuration 4 - The purge media may
be either a liquid or a gas.
Outlet Connections
5. Fast Loop Out - connect to the return
transport line. This line must be at lower
pressure than the process supply line
and is typically downstream from the
sample point.
6. Relief Outlet (option) - connect to a
sample disposal. This line will open if an
overpressure event activates the relief
valve.
7. Grab Sample Outlet (option) - connect
to a grab sample unit to collect samples
for analysis.
8. Oily Drain × 2 (Vent) (option) - connect
to an oily drain or sample disposal
suitable for the system media.
