strip (SQB-V)
General information
*AD/V sealing elements with a valve are reusable seals (patented), have been internationally successful since 2006.
All Wolf sealing elements (valve) fulfil the requirements of many European telecommunications network operators, including T-Com TS 0307/96 (approval no. Wolf 2005-08-11 ADE 100 (valve), France Telecom RSD CSE C75-11H, British Telecom LN584 (02/2011). The leak rate (diffusion rate) of the Wolf sealing elements is far lower than the T-Com requirement and the leak rates of competitor products.
Wolf sealing elements provide the user with a durable, reliable seal up to 0.5 bar/ 5 m water column in a temperature range of -15°C to +30°C (+45°C for a short period of 4h).
To meet application-specific requirements, the sealing elements are available with different coating materials:
| Prod.-No. 20.1 | 20.2 SQAD/VSAP | sealing strip (new development in 2022) for tightness against temporary buildups of water up to 0.8 bar / 8 m water column |
| Prod.-No. 20.3 | 20.4 ZKAD/V | Cellular rubber coating (ZK) for installation in stagnant or running water (Product info PI 20.3-04) |
Sealing element (uncoated):
The sealing cushion is made of a five-layered aluminium laminate. The high quality of both material and processing guarantees a very low diffusion/leak rate of ~ 0.73 mbarl / year and ensures a long service life.
The filling unit:
In order to be able to fill the sealing cushion several times (4 times), a patented metal air valve with a plastic-coated valve extension is connected to the sealing cushion by means of a heat-seal welding process.
The pressure is filled via a pressure hose, which is plugged onto the sealing cushion to fill the car valve. After the pressure has been filled, the valve is sealed pressure-tight with the valve cap.
Sealing element | SAP-sealing strip Prod.-No. 20.1 & 20.2 |
Sealing tape | Self-sealing SAP-sealing strip [Prod.-No. 27] consisting of PES/CO tape with integrated SAP nonwoven (SAP powder based on polyacrylic acid, directly bound to the nonwoven) The long edges of the sealing tape are sewn with a 5-thread safety stitch for multiple use. |
Advantage | Enormous absorbency & high swelling capacity after contact with rain or tap water |
Tightness | ensures tightness up to 0.8 bar/ 8 m water column (temporary water seepage) |
| Polymer gel: Tightness against creeping gases (volatile halogenated hydrocarbons in the soil air ≤ 100 mbar) |
Installation | Without lubricant |
Removal | Simple & non-destructive. No adhesion to cables or duct |
Tightness after water contact | Less than 1 min. on contact with water (rain or tap water) |
Reuseability | Reusable (re-installation) after complete drying of the SQ-sealing strip |
