SMC Networks AV2000 Manual page 3

Be sure to read before handling. Refer to pages 14-21-3 to 14-21-4 for Safety Instructions and Common Precautions.
Piping
Caution
1. Preparation before piping
Before piping is connected, it should be thoroughly blown out
by air (flushed) or washed to eliminate cutting chips, cutting
oil, and other debris from the pipe inside.
2. How to wrap a pipe tape
When connecting pipes and fittings, etc., ensure that cutting
chips and sealing materials from the pipe threads should not
get inside the valve. When a pipe tape is used, leave 1.5 to 2
thread ridges exposed at the end of the pipe.
3. Tighten threads with the proper tightening torque.
When screwing fittings into valves, tighten with the torques
given below.

4. Piping to products
When piping to products, avoid making an error of supply port,
etc., by referring to the instruction manuals.
5. F.R.L. module combination
When connecting to a modular F.R.L. combinations (AC20 to
60), select one of the spacers, which are included. (Refer to
page 14-2-10 for details.) However, modular combinations
with AC40-06 are not possible.
Furthermore, connect soft start-up valves to the outlet side of
the F.R.L. combination.
6. Inlet side piping conditions
The nominal size of the piping material's or equipment's bore
should be equal to or larger than the soft start-up valve's port
size. The composite effective area of the inlet side's (P port
side's) piping or equipment should be equal to or larger than
the values below.

When the piping is restricted or the supply pressure is
insufficient, the main valve will not switch and air leakage may
occur from the R port.

Lubrication
Caution
1
. The valve has been lubricated for life at the factory, and does
not require any further lubrication.
2.
Use turbine oil Class 1, ISO VG32 (with no additives), if
lubricated. Besides, if the lubrication is suspended halfway,
the original lubricant will be lost and may result in a
malfunction. Be sure to keep lubricating continuously.
Refer to the brand name table given below for lubricants by
each company, comforming to turbine oil Class 1 (with no
additives), ISO VG32.
