3.0 Disassembly
Prior to any servicing of a Kelso Valve, ensure all participating personnel have adequate
personal protective equipment.
3.1 Procedure
1. Remove the dome cover securement bolts. All bolts should have a locking
means (a split lock washer and Loctite). Lift the cover off, invert the cover and
utilize as a container for the remainder of the valve parts
(Figure 3.1)
.
2. If equipped, remove the debris\bee screen. Screens are installed on the
valve to prevent foreign material from entering the valve. A single pin
secures the screen to the valve and can be removed by hand
(Figure 3.2)
.
3. Loosen and remove the lock nut from the adjustment screw.
4. Rotate the adjustment screw counterclockwise, lowering the spring block.
This will relieve the tension on the springs. Rotate the adjustment screw until
the spring pressure is completely relieved
