Sun Hydraulics CBEA-CHN CBEACHN Counterbalance Valve. The valve appears to be unused. There is 3 very small nicks in the valve that you can see in the last 3 photos. There is one on the threaded section, one on the section above the threaded portion, and one on the top. I don’t think they will affect the function of the valve. If you are not happy with it I will happily accept a return and refund your money. What you see in the photos is what you will receive.
