Setting the Pressure Relief Valve

[tux]

I want to make sure we are setting the pressure relief valve correctly.

We are pumping up the system, then adjusting the valve so that it will hold pressure at 125psi.

In other words, we're not trying to adjust it so that the pressure never goes above 125psi even with the pump running.

This means that the maximum pressure in the system is a bit higher than 125psi. I can't remember exactly, but the needle on the high side might bounce up to 140 at times when the pump is on. Then when the pump stops the pressure relief valve will continue to vent until the pressure comes down to 125psi.

Does this sound right?
