Cleaning and Inspection
1. Place the valve body, and all valve
components, in a solution of detergent and
warm water, and carefully clean with the
tube brush. Corroded parts should be soaked
in a 50/50 solution of vinegar, and water for
1–3 hours, then re-clean, thoroughly rinse,
and inspect for corrosion and damage. If the
body or stem, shows any signs of damage,
the entire valve should be replaced.
2. After all interior and exterior surfaces have
been cleaned, dried and inspected, install the
new seat (5), and thread it all the way
down, using the flat blade screw driver.
3. Install the thin copper washer (2), in the
body.
4. After inspecting the stem, lightly lubricate the
stem shaft (3), then install the new washer
(4), packing (6), into the packing nut (7), apply
a small amount of Christo lube on the packing
nut threads.
CAUTION
Use care, not to scratch the valve body seat
area, when cleaning.
NOTICE
If the valve body shows signs of corrosion and
or contamination, the valve should be removed
from the HP block, and the HP hose for
cleaning.
NOTICE
Lubrication should be done sparingly, on the
stem shaft, and packing nut threads only.
