Hi guys, i'm new to this forum and need some guidance for my excavator thumb build. Anyone here know what kind of valve this is? Relief? My machine is grey hitachi same model with deere 35d mini excavator, hitachi parts catalog stated it as valve but deere stated it as relief valve. ** The valve located on my aux hammer circuit.

Appears to be a directional control valve with work port relief valves. I believe also has load check. Should work for a thumb.
