U-20806/U-20807 Adjustable Vertical Indicator Posts
Installation

installation instrUctions
Post Targets must be positioned for
use with the appropriate number
of turns to open the post indicator
valve. Improper positioning of the
Targets can result in an erroneous
indication of the open or shut
position of the valve. The U-20806
Indicator Post will accommodate
positioning of the Targets to operate
PIVs requiring 14 to 43 turns to
open; the U-20807 Indicator Post
will accommodate positioning the
Targets to operate PIVs requiring 49
to 75 turns to open.
NOTE: The Targets for the
U-20806 Indicator Post have
been factory set for use with a 6”
USPVH PIV and the Targets for the
U-20807 Indicator Post have been
factory set for a 24” USPVH PIV.
Consequently, Steps 6 –10 need
not be performed when installing
the U-20806 Post with a 6” USPVH
PIV (or with a PIV that requires
20
1
/
2
turns to open) or the U-20807
Post with a 24” USPVH PIV (or
with a PIV that requires 75 turns
to open).
Installing the Post
1. Completely close the PIV.
2. Place approximately 5” high
blocks onto the stuffing box flange of
the installed valve. Set the Indicator
Post onto the blocks and generally
centered over the PIV operating nut.
3. Slide out the Shipping Disk, and
allow the Coupling to drop down
over the PIV operating nut. Attach
the Coupling to the operating nut
with the Cotter Pin.
4. Remove the blocks and lower
the Indicator Post onto the PIV
stuffing box flange. Bolt the Bell and
stuffing box flange together using
the four Cap Screws and Nuts. Also
at this time make certain that the
three Cap Screws securing the Bell
to the Lower Barrel are uniformly
tightened.
NOTE: If the pipe is sloped, it may
be necessary to shim some of the
Cap Screws with steel washers,
so that the Post will be plumb and
the Stem will run true with the
center of the Post Head. Coupling
clearances can accommodate a
maximum pipe slope of 5 degrees.
It is recommended that a spirit
level be used to set the vertical
alignment of the Indicator Post.
5. Order Lengths “C” – “F,” partially
backfill the trench to a level 4 feet
below the final grade. Backfilling at
this point will help maintain vertical
alignment of the Indicator Post while
completing the installation.
6. Loosen the Set Screw, and lift the
Post Head/Upper Stem Assembly
just high enough to insert a Phillips
head screwdriver through Hole “A”
in the Upper Stem. The Phillips head
screwdriver will temporarily hold the
Post Head above the upper Barrel.
7. Remove the Wrench, pry off the
Cap, remove the Retaining Ring,
and then lift the Post Head clear of
the Upper Stem Assembly.
8. Position the Targets (see below).
9. Replace the Post Head, Retaining
Ring, and Cap.
10. Remove the Phillips head
screwdriver, lower the Post Head,
and tighten the Set Screw.
