Uszczelnienie dławnicowe ze sprężyną

Note: The above data are maximum values and cannot be used at the same time.

SURFRACE ROUGHNESS	Ra	Rmax
Sliding Surface Ød	≤0.2 μm	≤2.0 μm
Groove Base ØD	≤1.6 μm	≤6.3 μm
Groove Flanks B	≤3.2 μm	≤15 μm

Note: It is recommended to have 50% to 90% of the working surface material contact area value. If the operating media is gas we recommend having Ra value not to be above 0.15 μm.
INSTALLATION
K701 is to be assembly into open and closed grooves. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation the sealing element must be oiled with system oil.
NOTES
Depending on the PTFE material application values and their resistance can change. The permissible sealing gap values of K701 spring loaded rod seal is given in the below table.

PERMISSIBLE SEALING GAP
B (mm)	S max (mm)
X	50 Bar	150 Bar	250 Bar	350 Bar
2.4-3.6	0.10	0.075	0.05	0.05
4.8 strong>	0.20	0.10	0.075	0.06
7.1	0.25	0.15	0.10	0.075
9.5	0.30	0.15	0.13	0.075

Note: The largest sealing gap value occurring on the non-pressurized side of the seal does have a vital importance for the function of the seal and in this respect it is quite important to use the S value lower than the above indicated numbers.
