Well kids, we've saved

If we want our system
to operate safely,
a relief valve is essential!

Why?
Because there is always

If we get a pressure spike that
goes above our set pressure,
the relief valve will push open and
all that extra oil will be directed
back to tank. This will prevent
pressure buildup!

But what set

Our system
pressure is 2000
psi, so let's choose
2500 psi for our
set pressure. I don't
think we should go
much higher than
that because our
motor probably
couldn't handle it.

Relief Valves
RDDALAN — $60
Pressure Range: 500-3000 psi
Max Pressure: 5000 psi
RDDALBN — $45
Pressure Range: 300-1500 psi
Max Pressure: 5000 psi
RDDALCN — $90
Pressure Range: 1000-6000 psi
Max Presssure: 5000 psi
RDDALDN — $35
Pressure Range: 200-800 psi
Max Pressure: 5000 psi
We need to set our relief valve to 2500 psi.
Which relief valve should we choose?
We've picked all
the parts. Does that
mean we're done?

Don't we still need
to buy all the parts?
And then assemble
them?
