Warm Manual Valves

The Proton Improvement Plan II (PIP-II) is a particle accelerator being built as an upgrade of Fermilab
accelerator complex. The accelerator includes cryogenically cooled superconducting radio frequency
cavities using liquid helium (He II) at 2 K. The Tunnel Transfer Line (TTL) Warm Manifolds deliver helium
gas for operation of the accelerator. This specification seeks proposals for Warm Manual Valves that are
to be installed on the TTL Warm Manifolds.
