RITO supplies the A8VO80 valve plate for Handok Rexroth A8VO80 hydraulic pumps used on Hitachi ZX160 and ZX160LC-3 excavators.
The valve plate is the lapped wear surface between the cylinder block and the pump body. A flat, correctly finished plate holds pressure steady and limits the internal leakage that causes slow digging and oil overheating.
