UKRI-5581 Vacuum valves for ISIS RIKEN solenoid upgrade

Description

purchasing new vacuum valves for the ISIS RIKEN Solenoid Upgrade project. These valves are a critical part of this upgrade project and are essential for ensuring that parts of the beamline can be isolated during maintenance or in scheduled shutdowns to minimise equipment downtime and thereby ensure ISIS operations are not compromised. The existing system uses vacuum valves supplied by VAT. VAT are also the manufacturer of these valves.
