SPV is a two piece single acting piston seal which consists of a PTFE u-ring with metal spring as a tension component.
PRODUCT ADVANTAGES
- Superior static and dynamic sealing effect by the metal spring
- High resistance to chemicals and temperature changes
- Low friction , free of stick-slip
- High sliding speed
- Long service life
- Good dry running conditions
- Can be sterilized
- Low static and dynamic friction values
APPLICATION
Hydraulic and pneumatic cylinders , hot water valves , pumps , hot steam vanes , food processing , chemical and medical technology.
| MATERIAL |
| PTFE |
| STAINLESS STEEL SPRING |
| OPERATING CONDITIONS | |
| MEDIA | Hydraulic oils , hot air , water , steam , all media that do not react PTFE and stainless steel |
| TEMPERATURE | -150°C +250°C |
| PRESSURE | ≤350 Bar |
| SPEED | ≤15.0 m/sn |
Note: The above data are maximum values and connot be used at the same time.
| SURFACE 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
SPV 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 SPV spring loaded piston seal is given in the below table.
| PERMISSIBLE SEALING GAP | ||||
| B (mm) | Smax (mm) | |||
| 50 Bar | 150 Bar | 250 Bar | 400 Bar | |
| 2.4-3.6 | 0.10 | 0.075 | 0.05 | 0.05 |
| 4.8 | 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.
