Figure 9 - Tee Purge and Diaphragm Valve with Manifold Connector
for Maniflex Header shown with two cylinders per side.
For non-manifold system installation:
System 621 X01X-CGA (one pigtail per side) – see Figure 10 for locations of components:
1. Tape the male NPT connections on the pigtail assembly and street elbow assembly using the procedure
outlined on page 8.
2. After taping the male NPT connections, thread the 1⁄2 NPT of the street elbow assembly into the bulkhead
connector of the autoswitch as shown in Figure 10. Wrench-tighten.
3. Thread the 1⁄4 NPT connection of the pigtail assembly into the street elbow assembly as shown in Figure
10. Wrench-tighten. Note: while tightening the pigtail assembly into the street elbow assembly, a second
wrench must be in place holding the hex on the street elbow assembly. Failure to do so may cause the street
elbow assembly to loosen.
System 621 X31X-CGA (one pigtail per side with diaphragm valves) – see Figure 11 for locations of components:
1. Tape the male NPT connections on the pigtail assembly and diaphragm valve assembly using the procedure
outlined on page 8.
2. After taping the male NPT connections, thread the 1⁄2 NPT of the diaphragm valve assembly into the
bulkhead connector of the autoswitch as shown in Figure 11. Wrench-tighten.
3. Thread the 1⁄4 NPT connection of the pigtail assembly into the diaphragm valve assembly as shown in Figure
11. Wrench-tighten. Note: while tightening the pigtail assembly into the diaphragm valve assembly, a
second wrench must be in place holding the diaphragm valve. Failure to do so may cause the diaphragm
valve assembly to loosen.
