Tight against gas diffusion, dust, water (5 m water column) and chemical mixtures.
The high-quality, robust aluminium laminate
Adapts flexibly to the sealing area, independently of cable diameter and configuration or contamination by dirt
Ensures a long service life
Is resistant to chemical mixtures pH2 to pH12, fuels etc.
Coated with swelling material product group WO 22.2 QV-DBK
Ensures tightness up to 0.5 bar/ 5 m water column immediately on contact with water
Ensures tightness against gas diffusion (volatile halogenated hydrocarbons in soil air
Allows quick, easy removal (2 min). No adhesion! Makes damage-free removal possible 100 mbar)
The patented car tyre valve construction
Is simply inflated with compressed air (CO2-free!)
Makes on-site overpressure inflation technology simple
Allows flexible adaptation of the inflated cushion to fit the surrounding space and prevents buckling of cables and ducts or changes in technical transmission properties
Facilitates quick removal of air after cable retrofitting, by using accessory vacuum pump 33 VMSP or by changing the valve insert
Facilitates damage-free removal and re-installation
ADE/V sealing elements with a valve (Fibre Optics CT patent, registered under EP15154700.7), which were introduced with a petrolatum coating in January 2006 and redesigned with a swelling material coating (QADE/V-L) in 2013, have had undiminished success on the market.
The sealing element (valve) fulfils the requirements of the T-Com TS 0307/96 (Approval No. Wolf 2005-08-11 ADE 100 (valve)).
Wolf sealing elements provide the user with a durable, reliable seal in a temperature range -15°C to +30°C (+45°C for a short period of 4h).
Sealing cushion materials:
The flat tube cushion is made of 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.
