” (9 mm) branch supply line should include:
1. A shutoff valve for ON/OFF control.
2. An air filter/pressure regulator with a gauge for pressure control.
3. Mini-lubricators located at each vacuum receiver.
Install a quick-disconnect fitting or a shutoff valve in the compressed air piping leading to the
vacuum receiver atmospheric valve to speed receiver cover removal for cleanout or service.

Connecting Vacuum Receivers with Sequence-T Valve Compressed Air Lines
See Figure 32 on the following page for an illustration of a typical sequence-T valve. Critical
dried resin systems sometimes require sequence-T valves to prevent drawing humid atmo-
spheric air into the material supply. Sequence-T valves are usually installed in the vacuum
header above the vacuum hoppers.

Note: The sequencing valve is located in the cover on SR Series vacuum receivers if
you selected the internal sequencing valve option.
If mounted in the vacuum line, connect the sequence-T valve to a 60 psi to 80 psi (414 kPa to
552 kPa) source of clean, dry, lubricated compressed air.
