As the pop off pressure is increased, the blowdown ring will have to be screwed down further away from the bottom of the valve (aka feather). This creates a larger huddling chamber, which reduces the reset differential. If you increase the tension on the spring without adjusting the blowdown ring, t...

This might help

Depends on what it's for. I have every size on my 2.5" engine.

Had limited stock of the 3/16” and 1/4” straight globe valves at first but they are available again.

AFLAS is the superior choice for steam applications

You definitely want some friction on the trip rod. You would have a really hard time introducing so much drag on it that it interferes with the pump's operation, especially if its from a rubber o-ring. Having the reversing valve move out of place due to being too free would be a much worse problem t...

These are designed with 15" gauge locomotives in mind. They are not any particular scale, just designed around 3/8" pipe and 120 gallons/hour capacity.

Cleaning does very little to help a safety valve, at least in our scale. If the valve was hanging up after popping (most likely scenario in my opinion) cleaning won’t help. Would be very cautious about doing so, especially mechanically. The shape and size of the seat and valve are critical, and any ...
