Selection Guidelines for High Temperature Use Packings■ Number of Rings and Tightening Stress
Table 1 shows the recommended number of rings(combination method), tightening stress, and compression
ratios for high temperature use packings (low torquecombination GRASEAL packings and Super Seal packings)

Because these packings have exceptional sealing
performance, sufficient seal performance may beachieved with a fewer number of rings as compared towhen using asbestos packings.

■ Alignment of Packing Combinations
As a rule, our TOMBO No.2200 series, TOMBO No.2205
series, TOMBO No.2250-A and TOMBO No.2930 products
cannot be used alone. The TOMBO No.2200 or TOMBO
No.2205 packing should be sandwiched between the
TOMBO No.2250-A or TOMBO No.2930 (etc.) adapter
packings, as shown in the diagram below.

Fig. 4 A High Temperature Use Valve Packing Combination

10■ Metal Sleeve Usage
Because these packings have exceptional sealing
performance, sufficient seal performance may be achieved
with a fewer number of rings as compared to when usingasbestos packings. For existing valves that use a large
number of packing rings, we recommend the use of a metal
sleeve in order to avoid excess friction resistance.
Metal sleeve specifications are as follows:● Material: SUS304 or SUS403, etc.
● Shape: double split● Dimensions
Inner Diameter: Stem diameter + 0.5 mm(deviation tolerance h7)
Outer Diameter: Stuffing box diameter - 0.2 mm(deviation tolerance H7)
Height:Ls=D-n×hp
Ls : Sleeve Height (mm)
D : Box Depth (mm)n : Number of Packing Rings
hp : Nominal Packing Height of 1 Ring (mm)Sleeve resistance of packings is indicated by μk value.
The μk value is determined experimentally according to
the following formula, and the resulting μk values areshown in Table 2 below.
(1) Stem travel resistance
F＝μ・k・π・D・H・P

Caution: When installing a TOMBO No.2200 series or
TOMBO No.2205 series single cut product, besure to open the packing in the axial direction,
as shown in A of Fig. 5. Opening the packing
as shown in B could result in damage.

Note: μk values (frictional coefficient × lateral pressure coefficient) havebeen experimentally determined, but these values can vary depending
on a large number of factors such as the size of the packing, the numberof rings, magnitude of the tightening force, stem diameter, stem
finishing precision, temperature, internal pressure, etc., meaning that
an absolute μk value does not exist. When designing actuators, etc.,
please take into account a sufficient safety factor.
