3/4 inch BSP fitting progressive lift safety valve. CNC-machined bronze body, stainless steel ball and spring.

We fit these to all our "Estate Railway" range locomotives - running at 150pi working pressure - as well as replacements for secondhand engines that come in which have safety valves that either don't open or shut reliably, or accumulate (or all of the above if you're unlucky).

Supplied assembled, but will require to be set to working pressure, after which the supplied grub screw is used to lock the adjusting collar.
