Rust, sand or similar pollution int he medium, especially when rinsing
the system before the first setup, can cause buildup around the valve
seat. This can cause leakage of the valve seat.
The ventilation opening must be assigned and the ventialtion carried
out in such a way that neither persons nor the environment will be in
danger by penetrating medium.
For ventilation of a blocking valve according to DIN 16270 proceed as
follows:
1
Open valve (2)
2
Open the valve (3) carefully until air escapes
3
Close the valve (3) as soon as medium penetrates
The ventilation is hence finished.
When the prepressed packing is stored for a longer time, its sealing
ability can deteriorate. If necessary, the seal must be retightened at the
time of setup. The procedure is described in chapter "Maintenance
and fault rectification".
