Eccentric Engineer is proud to offer a true-to-scale safety valve for the first time in 1:12 scale!

These valves truly “pop” at their set pressure and reset at just a couple psi, as a boiler safety valve should. High quality nickel alloy springs have been custom made that will hold their spring rate for a lifetime of reliable service.

Valves can be set from 80psi-150psi, and each valve comes with a card certifying that the pop-off and reset pressures were tested and verified under steam.

Boiler adapters for 1/16” NPT, 1/8” NPT, M10x1 and M12x1 are stocked.
Please add a custom adapter to your cart if you need something other than what we provide!

You will be prompted to select your boiler adapter size and valve pressures after adding items to your cart.
