General Notes
Safety valves and overflow/pressure control valves are high quality fittings that
need to be handled carefully. 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 valve seat can be impaired by dirt particles,
Teflon tape and other seals as well as through welding beads and metal chippings
among others.
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.

industry, the medical, pharmaceutical and cosmetics industry as well as recycling
and the chemical industry and in clean-service applications under consideration of
the regulations specific to the systems and suitability of the sealing materials and
valve design.
