Mount Vernon, WA | There are actually two return lines on a power beyond valve. One is designed to go straight to sump, and the other is to carry high pressure oil on over to the next valve in series with the first.
The power beyond circuit is not taken directly off the pump necessarily, but rather it is used to power another high pressure function downstream of the first valve. Using a non-power beyond valve upstream of another will subject the exhaust core of the first valve to pressures it is not designed to see, and could crack it. | |

Can we talk power beyond circuits
