Replacement Springs for Hydraulic Control Valve

Inside almost all hydraulic control valves, there are springs that bring the spools back to their original position.  When these springs are damaged, rusted or worn out, they do not bring the spool back to first position as designed.

To correct this problem, we can do one of 2 things:

Find Replacement Springs:

Hydreco, Husco, Commercial, Cessna, Komastu and other valve manufacturers usually have replacement springs available.  We can help find these for you if we don't have them in stock.

New Springs for Out of Production Valves:

If your valve is no longer supported by the OEM, we can have new springs built for you, as long as there is one good sample or detailed specs available.

Here are some VERY rusted springs from a valve we just got in.  Not sure if we will be able to clean up or not.  We will post a full rundown of this job in our Recent Valve Rebuild section.
