4695888 Genuine Hitachi signal valve for Hitachi excavator ZX225USLC-7

This shuttle valve (part no. 4695888) is an OEM blue-label accessory for Hitachi ZX200-5B/ZX350LC-5B excavators, designed for the hydraulic system. Its core function is to enable one-way conduction and pressure switching of dual hydraulic oil circuits, precisely controlling the action logic of booms, buckets and other actuators, ensuring stable hydraulic power distribution during multi-circuit operations—it’s a key hydraulic component for smooth composite actions.

Made of high-strength cast steel valve body for construction machinery, its inner wall is precision honed (roughness ≤Ra0.8μm), paired with high-pressure resistant seals (withstanding 35MPa). It adapts to the high-frequency, high-pressure hydraulic conditions of excavators. The blue label certifies OEM process standards, offering excellent corrosion and wear resistance, enduring long-term hydraulic oil erosion to maintain stable valve sealing and flow efficiency.

It strictly matches the hydraulic circuit interfaces of ZX200-5B/ZX350LC-5B, allowing direct replacement without modification (compatible with original gaskets), greatly reducing hydraulic system maintenance time. Its stable pressure switching performance avoids hydraulic shocks during multi-action operations, reduces actuator component wear, and improves the smoothness of machine operations and the service life of the hydraulic system.
