Thus, not only the nominal sizes of the valves,
but also the nominal sizes of the pipes, can
be reduced by at least one nominal size. A 7010
valve in nominal size 32 can even replace
a conventional valve with a nominal size 50 without
reducing the flow rate. The entire steam
package is thus more compact and more economical.
Also the 3-way valves and even
the straight bodied valves of Schubert & Salzer
produce advantages in terms of Cv values
relative to these conventional solutions
