FEEDBACK - I've managed to get hold of a OCV from a good system and put it on the one we are having trouble with and guess what - it works OK.
Yesterday we tried a different sort of OCV and that didn't work either.
The pressure gauge on line B for the good valve shows the pressure builds up (as...
Thanks itsmoked, but we have tried to "bleed" it now and again but it still didn't work. One thing though, when it was reading zero on the gauge I cracked a joint in line A and got a reading on the gauge. We still couldn't control it though.
I set the previous units by starting it then as the...
I would guess any material and treatment nowadays would be far superior to then. Gleason would argue Gleason & Klingenberg vice versa.
It would depend what machines the gearshop has.
Try shot peening after manufacture, this will bump the fatique rating up

The DCV's operate simultaneously to operate the two cylinders. They are both loading on the annulus side.
Can you tell me why when I operate it, the pressure in line B is zero until the cyl 1 bottoms out then it climbs to the...
