Vacuum Braking (15) Implementation (8)

Working Under Less Pressure than the boiler, the vacuum brake ejector requires 60 psi to work most efficiently. I began to describe this in an earlier article.

The missing item was a gauge to measure the pressure entering the pressure reducing valve.
Ejector Pressure Gauge Mounting
The gauge is clamped to the upward tube and marked mid-way between 40 and 80 psi.

Steam gauges are always fed by a tube with a loop or dip before the gauge. It collects condensation and prevents the steam entering the gauge and melting the soft-soldered delicate parts inside.
