Product Description
706-88-00010 valve plate is a core precision wear part inside HPV132 main pump for Komatsu PC400-6 and PC450-6 excavators. It is fixed between pump cylinder block and pump housing with two arc oil ports to separate low-pressure oil suction and high-pressure oil delivery. Manufactured from high-tin bronze with mirror grinding and hardening treatment, it fits tightly with rotating cylinder block to form an oil film seal and minimize internal leakage. Stable hydraulic pressure output is guaranteed even under long-hour heavy mining operation. Every valve plate passes flatness and sealing inspection before shipment for direct plug-and-play replacement without modification.
