Product Features
- Precisely honed spool matched with high-quality spring assembly, dimensional tolerance strictly meets OEM standards. It features sensitive pressure feedback to stably adjust the displacement of the main hydraulic pump, effectively solving common failures such as engine lugging, weak digging power and pressure fluctuation, ensuring stable constant-power operation of the hydraulic system.
- Made of high-strength wear-resistant alloy steel with professional surface hardening treatment, resisting hydraulic oil corrosion and high-frequency reciprocating friction for extended service life. Precisely machined sealing groove works well with standard O-ring to prevent internal leakage. Direct replacement for main pump regulators on Hitachi EX200-5, EX270-5 and related models, easy for installation.
