MAINTENANCE
Routine inspections of the system are recommended. The need for maintenance usually becomes apparent from
inspection and indications of improper operation. Typical trouble indications include leakage from valves or piping
connections and excessive venting through relief valves. Keep a permanent log of all inspections and repairs performed.
Such a log can be valuable in evaluating performance and scheduling maintenance.

Always observe the safety precautions at the front of this manual and follow the instructions given in this section. Before
working on the system, properly empty the vessel of liquid and relieve pressure on the vessel and piping. Do not allow
unqualified persons to attempt repairs on this equipment. Refer to the Trouble-Remedy Guide in this manual for
assistance in troubleshooting.
Leak Test
After making repairs requiring disassembly or replacement of components, leak test all valves or piping joints that were
taken apart and reconnected. Apply leak detector fluid to the test surface. Large leaks instantly form large bubble
clusters, while fine leaks produce white foam that builds up more slowly. All leaks must be repaired and retested before
the system is returned to service.
Globe Valves
All of the globe valves (V-2, V-3, V-4, V-5, V-6, & V-7) are easily removable. Tapered pipe thread connections are used
at the inlet and outlet. However, the valves may be rebuilt without removal from the system. All of the globe valves use
the same rebuild kit. The Taylor-Wharton part number for the rebuild kit is 1750-9C35. All valve components, except
the body, are provided in the kit.
