withdraw liquid helium
simultaneously? We do not currently
have tanks with this configuration;
however, a bayonet adaptor might be
able to be configured to meet this
requirement.

E-1 already describes a “manual iso
Yes, the “manual iso valve Cv >=23.5” in
valve CV >=23.5”. Is this redundant to (E)(5) is redundant because (E)(1) identifies the description in E-1 or is it intended the requirements of the connections and to describe something else?
(E)(5) identifies the Cv requirement of the
Manual Outlet Isolation valve.
