To add to that, a notable number of people have asked which pipe size they should use if they haven’t tapped their steam dome yet. It really does not matter and is entirely a matter of preference. The hole through the center of the adapter is the same diameter on every size, and the pipe thread has ...

1.6" safeties have the option of 1/8" or 1/4"
2.5" are 1/4" or 3/8"

Safety valve project is nearly complete. All that’s left to do is square up the springs and finish the boiler adapters. I expect to start shipping valves next week after 4th of July. Now would be a good time to order if you’re interested! https://www.eccentricengineer.com/safety-valves IMG_9939.jpeg

Just FYI, I'm working on making straight and angled check valves in 5/16, 1/4, 3/16, 5/32, and 1/8 MTP. Hope to have them ready by August.

Will EE have the injector starting valves in stock any time soon? I hope to make more sooner rather than later. My plate is pretty full at the moment though! I will also be looking into making a 1/4 turn injector starting globe valve to go along with the globe valve project. It would be a standard ...

Personally I would highly recommend a 1/4 turn valve over a quick on/off valve. They are just as fast to operate, but can still be cracked open which helps with priming in less desirable scenarios, like a leaky check valve or hot feedwater.

Hi all, I'm pleased to let you know that the 1.6” and 2.5” safety valves are now available for pre-order! Current estimated delivery date is late June. 1.6" Safeties can be pre-ordered here: https://www.eccentricengineer.com/safety-valves/16-scale-consolidated-safety-valve And the 2.5" Sca...

Hi Fender If this is a superscale injector, where is this washer located, and how should it be facing. Maybe that is also the problem. The locomotive I am talking about, was build by WLS member Don Cornell, and 0-4-2 the Locomotive has side water tanks, no Tender. As I said I will post photos of th...

Not starting until 60psi is most likely due to a very minuscule air leak between the water valve and injector. Air leak symptoms typically improve at higher pressure rather than worsen. However, cutting out at 80psi is a bit more unusual. The only things that could cause this in order of likelihood ...

If the injector on there is truly a SuperScale injector it should work fine from 40-150psi. If it’s only working from 60-80psi then there is a problem somewhere somehow with the installation.

A "future product" page has been added for check and globe valves! https://www.eccentricengineer.com/globe-check-valves If you are interested in these it would be greatly appreciated if you could take the time to fill out the form at the bottom of the linked page! This will be a monumental...

So why does the feedwater heater take a different check than the injector? The pump side is a bit more complicated to help reduce losses from the repeated hammering of the check valve. Larger diameter, less valve lift, a longer valve guide, and a spring all help reduce losses every time the valve c...
