Hi all
Just a quick question.. Will a sticky spool in a servo valve cause larger hysteresis with larger surply pressure?
The reason I ask is that we use valves rated to 3000 psi and in the data sheets hysteresis is given for 3000 psi. Howevwe our systems only deliver around 1000 psi and I would like to know what kind of hysteresis I can expect.

Thanks and best regards
Hans

Sorry I meant if higher operating pressure would cause LESS hysteresis :)
