General Notes
Overflow valves and pressure limiting 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. The
tightness of a pressure limiting / overflow valve can be impaired when using hemp,
Teflon tape, as well as through welding beads, among other things. Also rough
handling of the finished valve during storage, transport and assembly can result in a
valve leaking. If the valves are painted, make sure that the sliding parts do not come
into contact with the paint.
