6-3.11 Ball Valves
a.
Ball valves are utilized at the fuel dispensing assembly and at the tanker-truck unloading spot. See para.'s 2-
5.3h, j, and m and Fig.s 2-48, 2-50 and 2-53 for technical description. Complete detail is found in Appendix A (Pittsburg
Brass Mfg. Co.). A typical ball valve cross section and nomenclature is in Fig. 6-20.
b.
Preventative maintenance is limited to:
"D"
1. Inspect all valves and check operability routinely. Note leakage or faults. Report findings for corrective
maintenance action. The packing gland nut can be tightened up to stop stem leakage. If repacking is required, it should
be handled with the valve out of the system. Follow the instructions for valve adjustments found in Appendix A
(Pittsburgh Brass).
"W"
2. Clean up the valve.
6-3.12 Needle Valves
a.
A needle valve is utilized on the sampling assembly Fig. 2-22, para. 2-4.8. Detailed information is in Appendix
A (Anderson, Greenwood & Co.). A cross section and nomenclature are shown on Fig. 6-21 for maintenance
convenience.
b.
Preventative maintenance action is:
"D"

6-3.13 Sampling Assemblies
a.
Technical information on sampling assemblies is in para. 2-4.8 and Fig. 2-22.
b.
Preventative maintenance is:
"D"
1. Check the units daily to assure that they are safe and operable. Treat valves as noted in para. 6-2.11 and 6-

Technical information on the meter strainer assemblies is covered in para. 2-4.6 and the assembly is shown on
Fig. 2-19. Detailed information on the meter is in Appendix A (Smith Meter Co.) and also on the strainer under
(Weamco). The air release head attached to the strainer is in Appendix A also (Smith Meter Co.). The detailed
information in Appendix A is important and should be reviewed carefully. A cross section of the strainer is shown in Fig.
6-23 for the convenience of maintenance.
b.
Preventative maintenance actions recommended on the meters are:
6-11
