4.0 Inspection
The Valve and most components can be visually inspected without removal from the
tank car; however, a proper inspection should be made whenever the valve is rebuilt or
when suspect operation warrants.
Kelso utilizes a compound authentication procedure whereby all seals are etched
with the pedigree compound and tracing number. If the seal does not have etch,
refer to the car owner for the proper pedigree compound.
4.1 Components
1.
The elastomeric seal must be replaced when the valve is rebuilt. Upon
inspection the seal should be secured and concentric in the sealing disc groove
(Figure 4.1 & 4.2).
The seal should be free from tears, folds, abrasions,
cracking and a buildup of debris. Replace when any of these defective
conditions occur.
The seal has been manufactured with a proprietary composition and should
only be replaced with Kelso supplied material.
Any necessary replacement parts should be purchased through Kelso
Technologies.
