Hitachi Construction Machinery Genuine Parts — Relief Valve, P/N 4469380 | Qty: 5

Item Overview

These are five new, unopened Hitachi Construction Machinery Genuine Parts hydraulic relief valves, part number 4469380. This is a cartridge-style hydraulic relief valve used in the main hydraulic control valve assembly of large Hitachi ZAXIS and EX series excavators. Relief valves of this type protect the hydraulic circuit by limiting maximum system pressure, opening to divert flow when pressure exceeds the set point and preventing damage to pumps, motors, cylinders, and other hydraulic components.

Each unit is individually boxed in the distinctive orange Hitachi Genuine Parts OEM carton with holographic "GENUINE PARTS" security label, confirming authenticity. The boxes bear the Hitachi Construction Machinery Co., Ltd. branding and "MADE IN JAPAN" designation, consistent with Hitachi's policy of manufacturing critical hydraulic components in Japan.
