Auxiliary hydraulic valve relief setting

Postby J3 Driver » Sun Jan 20, 2019 8:40 pm

Getting ready to add this valve to the cub so my son can have a hydraulically angled snowplow.

I know the cub hydraulic system operates at a max pressure of 1500 PSI and at range from 1100-1500 psi.

Where you you guys recommend setting the pressure reilef port st so it doesn’t damage the touch control system?

Thanks.

Keith.

On mine I set it as low as it would go and still allow the cylinder that angles the blade to work.

I installed my hydraulic blade angle in 2004. My valve is set the same way, just enough to do the job.

Back when I was involved with making different projects with added control valves, I found that backing things off and then slowly adjusting the relief up to 1000 was sufficient and always worked for me. Make sure you post how you adjusted the valve you have so others can see.

Thanks for the replies. I think I’ll have it set at around 900-1000 psi. I have a neighbor that works at a hydraulic shop. We plowed out his driveway the other day and he offered to take the valve to work and set the relief pressure on it for me. That will be easier than me trying to rig something up and rules out the chance of damaging my hydraulic system.
