pressure relief valve

Postby sacveggieguy » Fri Apr 18, 2008 2:47 pm

This is a question 4 Sunwizard. I set up my centrifuge based on your design and the question I have is with my pressure relief valve I used the one you recomended from graingers and used the spring they said to use in the instructions the red one which should give me betwwen 51 and 100 psi and im only getting about 50 psi and bypassing quite a bit of oil any ideas?

Thanks Paul aka Sacveggieguy

If you have it adjusted to the max, then use the next bigger spring, and start with it low. The instructions psi ranges are for water, not VO.

adjusted to the max meaning screwed all the way in putting more pressure on the spring right?

I was wondering about my setup, i dont have any type of pressure valve on my dc cf and i just use my tee and valve to get it at 90 psi. is this ok or am i doin it wrong ? It seems to run and filter fine. also can i just use an air compressor pr. reg. to adj. my pressure?

A pressure relief valve is better since if you get a jet that clogs, you would bend your rotor without one.

No air regulators are way different.
