At the design stage, safety and func-

Analytical verifications are made based
on customer requirements, and interna-
tional standards (e.g. ASME), as well as
ANDRITZ HYDRO internal instructions.
Modern ANDRITZ HYDRO valves offer
numerous innovative technical features,
which appeal to customers.

main components of butterfly valve
Spherical valves are mainly used in high
head applications, whereas butterfly
valves are selected for the low to medi-
um head range. Indicative design limits
for each valve type are shown in the di-
agram above.
Both valves allow flow in both directions
and fit perfectly for the use in the water-
ways of reversible pump turbines. They
can be equipped with service and main-
tenance seals to allow significant reduc-
