General Notes
Safety valves are high-quality fittings which require a particularly careful handling.
The sealing surfaces are precision-machined at the seat and cone to attain the
required tightness. Always avoid the penetration of foreign particles into the valve
during assembly and during the operation. Rough handling of the finished valve
during storage, transportation and assembly can also result in a safety valve leaking.
If the safety valves are painted always ensure that the sliding parts do not come into
contact with the paint.
