1/2 inch BSP progressive lift safety valve

1/2 inch BSP fitting progressive lift safety valve. CNC-machined bronze body, stainless steel cap, ball and spring.

We fit these to all our "Clubman" range locomotives - running at 120pi 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, complete with setting tool and hex wrench. The valve will require setting to the required working pressure before use.
