Leaky valve? Stuck spool? We have rebuilt main hydraulic control valves for Deere, Hitachi, Caterpillar, and Komatsu excavators in stock and ready to ship! Our technicians go the extra mile on these valves to make sure your rebuilt valve lasts as long, if not longer, than the original. Each valve is meticulously taken apart, checked to ensure any worn/damaged parts are replaced, and are fully resealed with OEM seals/o-rings. As always, we take cores back in any condition as long as all parts are returned with the core!
