Pneumatic Hookup Procedures
Prior to connecting the supply air to the spool valve, flush the system to remove any debris or contaminates. Galva-
nized pipe can easily flake and contaminate the system and therefore is not recommended. A 40 micron point of use
filter at every device is recommended.
4-Way Spool Valves
The TopWorx spool valve is a 5 port, 4-way valve driven by an internally mounted pilot. The spool valve supply port
and work ports are marked as follows:
***Never Plug, Block or Restrict Port 5***

Highly Recommended
TopWorx highly recommends Locktite 567 brand thread
sealant. Do not use a hard setting pipe compound. If Teflon
thread seal tape is used, start the wrap on the second
thread from the leading thread of the fitting. This will pre-
vent tape shreds from contaminating the spool valve seals.
Breathers (AL-M31) should be installed in the exhaust
ports to keep debris from falling into the spool valve and
damaging the seals. This must be addressed prior to instal-
lation, or storage.
A flow control may be used in Port 3, but should NEVER
BE USED in Port 5. Any blockage or restriction may cause
an internal pressure build-up inside the enclosure and pose
a safety issue.
