I need a couple of 90 degree wall mounting isolator valves for the H/C feed to a basin, I've seen them in hotels but can't find them in the on-line catalogues. Here's a (poor) attempt at a description: they have a built-in service valve, the pipe connects to them behind a panel, they're fixed to the panel, a standard flexi tail connects the tap to them.
Any suggestions where I can get some?
