2-60. ELLIPTIC VALVE MAINTENANCE.
This task consists of:
General Mechanics Tool Kit (Appendix B, Section III, Item 4)
Tape, Anti-seize (Appendix C, Section II, Item 30)
ROWPU shutdown (TM 10-4610-240-10).
Power shutdown (power source manual).
ROWPU piping drained (TM 10-4610-240-10).
There are four elliptic valves on the product manifold. All are removed and installed the
same. One is shown, the others are similar.
Loosen clamp (2) and remove flexible tubing (3) from adapter (1).
Loosen clamp (5) and remove flexible tubing (6) from adapter (4).
Remove two adapters (1 and 4) from elliptic valve (8).
Remove elliptic valve (8) from nipple (7).
Apply anti-seize tape to male pipe threads Be sure tape is wrapped in same direction as pipe threads.
Install elliptic valve (8) on nipple (7).
Install two adapters (1 and 4) on elliptic valve (8).
Install flexible tube (6) and clamp (5) on adapter (4). Tighten clamp.
Install flexible tube (3) and clamp (2) on adapter (1). Tighten clamp.
Operate ROWPU (TM 10-4610-240-10). Check for leaks and proper operation.
