Can you explain things a little better?

When things blow up or out, something made that happen.

What parts did you put back together?

Did you deadhead one of the hyd lines?

You have any pictures of the valve?

Show what parts blew out.

Thanks for your reply.I dont know anything about hydraulics but the bits that came out were on the control valve body,next to the responce contol knob is a chamber which has a speed contol piston,spring,plug,cover of which the spring and cover blew off pouring oil out.I was unsure if the front loader was seperate to the 3 point as the oil pipe from the filter branches off to the control body and front loader.What is deadheading the line?

In an open center hyd system, the pump flow is continuous.

If something blocks the flow and the relief valve can not handle it, something will blow up, be it a hose, fitting, valve burst, pump burst, etc.

Wondered if the problem could be with the red box,is there a filter inside?

I don't know what the pressure is , but I see water pipe and brass fittings.

i forgot to say it was the disc in the bottom chamber near the knob that blew oil out.
