Hello guys, a bit of help here. I need to know what kind of valve inside the picture here. Is it a type of relief valve?it has no poppet..
I assume it is a screw in cartridge? Where was it located? Was it screwed into the end of a work section of a spool valve? If so it could be a load check.
It screwed to my aux port, I'm building a thumb for my machine and this valve 0735916 puzzle me.. hitachi parts catalog describe it as valve only , but deere catalog write it as relief valve. Hitachi ( no.18 ) https://en.av-gk.ru/catalog/hitachi/1m7:zx30u-2/5f7e592b-b89a-463f-a2bd-c1c6d7707fa7/ Deere( part no.18-short ) https://avspare.com/catalog/deere/688/41720/304977/
From looking at the diagram, it looks to be a "Circuit Relief", or a "Holding valve".
Is this the location? (Red Circle) If so, it's a relief valve.
So can i connect my thumb cylinder to this port and set the screw on the back of the valve to lower the psi and use it as relief too? For info* the aux section is actually breaker aux port..
Yes, as show in the picture. But the valve are shorter compare to arm, bucket, boom relief valve next to it..
This is on the Aux Valve? You can drive the Thumb with it, in place of the breaker. Yes, the relief pressure will need to be adjusted as per the manufacturer's specs.
This the valve in the picture below
Thank for your help, now i can relief myself from buying another set of relief valve..
I have see both breaker (hammer) and thump plumbed into the same valve circuit using a manually Operated Diverter Valve. Although, the Relief Pressure must be fairly close to the same if doing so.
For a hammer circuit the valve must be adjusted to max to have good flow and pressure to the hammer. But for cylinder i'm puzzled before this since i never came across this kind of valve with no poppet in the center, that why i guessing between holding valve or pressure relief valve.
