Section Seal Replacement Precautions
•
Do not lubricate the O-Ring section seals
prior to installation. Compression of
lubricants can distort the valve body causing
spool bind.
•
If the stud nuts are not torqued to the
proper specifications, valve spools may bind or
stick, or cause O-Ring seals to extrude.
•
Replace the stud nuts and torque evenly to 13 -
15 Ft Lbs [17 - 20 Nm]. This is a dry stud
torque spec. Torque evenly to 10 - 13 Ft Lbs
[13 - 17 Nm] for oily studs.
Buna-N seals are standard for all
Parker
valve assemblies
