InstallatIon and maIntenance InstructIons
9. Turn the valve over so the installed sleeve
is on the flat surface.
10. apply a silicone base lubricant to the
sealing-nose radius of the installed sleeve.
also apply it to the second sleeve sealing
nose and O.d. of seal end.
11. install the second sleeve, following steps
1 through 5.
12. install second retainer per following steps,
depending on valve size.
13a. Smaller valves:
a. Place second retainer flange on the top
of the sleeve. align the retainer flange
bolt holes with the matching holes in
the round flange. align the i.d. of the
sleeve and retainer flange.
b. Check the sleeve bores for
concentricity; using a straight edge,
check the sleeve position in four (4)
places, 90 degrees apart in relation to
the installed sleeve bore i.d. adjust as
required to make the sleeve concentric
with the other sleeve.
c. install the retainer bolts, do not fully
tighten. Only tighten sufficiently to allow
installation of the next bolt. Continue
this until all bolts are installed.
d. Once all bolts are in place and
concentricity has been checked,
tighten the retainer flange bolts using
a cross pattern until there is a 0" to ⅛"
gap between the retainer flange and
the housing.
13B. larger valves (see paragraph 13C for
alternate method):
a. Place second retainer flange on the top
of the sleeve. align the retainer flange
bolt holes with the matching holes in
the round flange. align the i.d. of the
sleeve and retainer flange.
b. Check the sleeve bores for
concentricity; using a straight edge,
check the sleeve position in four (4)
places, 90 degrees apart in relation to
the installed sleeve bore i.d. adjust as
required to make the sleeve concentric
with the other sleeve.
c. using two or more C-clamps, pull down
the second retainer flange.
d. install the retainer bolts, do not fully
tighten. Only tighten sufficiently to allow
installation of the next bolt. Continue
this until all bolts are installed.
e. Once all bolts are in place and
concentricity has been checked,
tighten the retainer flange bolts
using a cross pattern until there is
a 0" to ⅛" gap between the retainer
flange and the housing.
f. remove C-clamps.
13C. larger valves, alternate method.
a. install threaded studs (at least one or
two studs per 90 deg of bolt circle) into
the drilled and tapped flange bolt holes.
b. Studs should be of sufficient length
to fully engage in valve body and
extend beyond the stack up of the
uncompressed sleeve and retainer
flange, plus nut height.
c. Place second retainer flange on the top
of the sleeve, over the installed flange
studs while aligning the retainer flange
bolt holes with the matching holes in
the round flange. align the i.d. of the
sleeve and retainer flange.
d. Check the sleeve bores for
concentricity; using a straight edge,
check the sleeve position in four (4)
places, 90 degrees apart in relation to
the installed sleeve bore i.d. adjust as
required to make the sleeve concentric
with the other sleeve.
e. Place a nut/washer on each installed
flange stud and using an alternating,
cross flange pattern, draw the retainer
flange toward the valve body.
f. install the retainer bolts, do not fully
tighten. Only tighten sufficiently to allow
installation of the next bolt. Continue
this until all bolts are installed.
g. Once all bolts are in place and
concentricity has been checked,
tighten the retainer flange bolts using
a cross pattern until there is a 0" to ⅛"
gap between the retainer flange and
the housing.
h. remove installed flange studs and nuts.
14. The valve is now ready for installation.
Keep gate in the open position until
valve is installed.
