Filling-pressure monitoring system with automatic regulation of
the filling pressure and power of p-joint-sealing cushions/V (valve)
Filling-pressure monitoring
system with automatic
regulation of the filling pressure
and power of p-joint-sealing
cushions (valve)
Ensures a controlled pressure-
filling of 150 mbar to 300 mbar
from below during installation
General
The sealing efficiency and service lifetime of p-joint-sealing systems are directly related to filling
pressure, which is temperature-dependent, and lateral movement along the x-axis.
It is therefore important to:
-
adhere strictly to the installation specification, VO 60.02 Pressure-filling of Sealing Cushions with a
Valve for Expansion and Movement Joints, and to provide proof of tightness.
reach the permissible pressure filling for reusable p-seals for movement joints (type L: 300 – 350
-
mbar and type S: 150 – 200 mbar (20°C +10°C)) during installation. This can be achieved by
using the filling-pressure monitoring system Art. No. 86.01 p-AK-MSMO, for example.
-
set up the filling-pressure monitoring system Art. No. 86.01 p-AK-MSMO for permanent
regulation of filling pressure and power after installation (because pressure fluctuates as a
consequence of movement along the X-axis in summer and winter, amongst other factors). Ceiling
or wall Installation is recommended.
carry out a visual inspection of the filling pressure (tightness) of the reusable movement-joint
-
p-seals in the course of routine joint inspections, adjusting the filling-pressure where necessary.
