Installing the New Packing
Packing (A2) strip length and quantity are shown in Table B. Ensure the inside and outside edges of
each ring are packed against the gate and packing chamber, so that each strip is compressed flat
and evenly. DeZURIK provides extra packing in their packing kits, but do not try to put more packing
into a layer than shown in Table B. If packing is for low pressure applications (40psi [2.7 bar]) contact
DeZURIK.
Do not compress the packing any more than
needed to stop leaks.
1. Ensure the gate (A3) is fully closed and cen-
tered in the body before packing.
2. If used, place the anti-extrusion ring (A9) or
scraper ring in the bottom of the packing
chamber.
Note:
Ensure that the anti-extrusion ring fits
tightly around the gate and that there is approxi-
mately
1/32-1/16"
clearance around the packing
chamber.
3. Assemble and pack the rings one at a time,
with the ends together, but not overlapped
Note
: Stagger the joints, on the long side of the
packing chamber. For packing rings, we recom-
mend using a square-ended wood or plastic tool,
driven by a hammer or mallet. Do not use a
sharp tool to pack the rings.
4. For packing systems with the packing cord (A8), assemble and pack one row of packing (A2) and
then insert the packing cord (A8). Assemble and pack the last row of packing. See detail below:
