5.0 ASSEMBLY PROCEDURE – UNISERT™ TYPE (5” VALVE)
NOTE: It is imperative that the workstation being used to assemble the
valve be clean and free of anything that could possibly contaminate the
grease such as metal shavings, dirt, rust, old paint, etc. Do not sand or
deburr near the workstation.
All assembly steps must be done with the valve pocket in the vertical
position. Any attempt to screw the adjusting nut in with the valve pocket in
the horizontal position could result in damage to the adjusting nut and valve
sealing components.
o
Check surfaces around the
valve bore inside the valve
pocket for sharp edges that
could cause cutting of the
insert o-rings. Then screw
the clean
adjusting nut
(12)
all the way into the
valve body to make sure
the threads are not
damaged.
o
After inspection remove the
adjusting nut and check the
roll pins (15 & 16)
in the
valve body by gently sliding
the
insert (7)
into the
valve. The
insert (7)
should move freely up and
down the length of the roll
pin slots without
interference.
