Pneumatic Hookup Procedures
Prior to connecting the supply air to the spool valve, flush the system to
remove any debris or contaminates. Galvanized 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 valve. The spool valve supply port and work ports are marked
as follows:
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
prevent tape shreds from contaminating the spool valve seals.
Flow controls (AL-M21) or 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 installation, or storage.
