Loctite 242
This Concludes Assembly of the Cylinder Valve
9. Install a new lubricated o-ring (16) onto valve body (12). Lightly
lubricate the threads of the valve body. Place cylinder in cylinder
vise jaws (pn 100398), secure in cylinder vise and screw the cylinder
valve into the cylinder by turning valve body clockwise until hand
tight. Using a 1-1/16 inch (27mm) crowfoot (pn FC34A) and foot
pound torque wrench, tighten the valve assembly into the cylinder
to 25 ft/lbs (34 Nm).
6. Install washer (3) and handwheel (2) onto spindle (10).
7. Secure the handwheel (2) to the spindle (10) by placing the
handwheel nut (1) on to the spindle (10) and tighten it down with a
large flat blade screwdriver until it stops.
CAutioN: Avoid cross threading the handwheel nut.
If resistance is felt while screwing the handwheel nut
on to the spindle, stop and start over.
8. Lubricate the o-ring (14) and install on the valve seat adapter (15).
Apply one drop of Loctite 242 to the small threads of the valve seat
adapter. Secure the valve body assembly in a vise, using a 5mm hex
key adapter (pn 8367A23) and inch pound torque wrench tighten the
valve seat adapter to 90 in/lbs (10.2 Nm).
1. Fill cylinder to 500 psi (34 bar) and listen for audible leaks. Sub-
merge in a fresh water supply and visually inspect valve for any leaks
that may be present. If no leaks are detected, fill cylinder to 3000 psi
(206 bar), again listen for audible leaks and submerge in fresh water.
If any leaks are detected, disassemble valve, replace worn parts,
rebuild and retest.
