Walter Frank to service PRV9i valves for Crossrail

May 2021

Walter Frank is proud to have won a service contract to maintain our PRV9i, FM Approved, pressure regulating fire-fighting valves, which are already inside the newly commissioned Crossrail underground tunnel systems.

The original contract called for a valve design that enabled frequent servicing; with the interchangeable nature of our PRV9i cartridge valves making this possible.

During 2016, 1560 PRV9i valves were installed across the project’s tunnels, deep under the streets of the centre of London.

We are proud to have supported the safe commissioning of one of the UK’s largest ever infrastructure projects.
