Product Features
- Original precisely‑mated ground spools inside valve body with high flow distribution accuracy. Smooth coordinated compound movements for boom, arm, bucket and swing with balanced flow output. Effectively resolve operation stuttering, inconsistent speed and compound‑action speed drop. Fully match original hydraulic logic and guarantee operating performance under heavy‑load digging and loading conditions.
- High‑strength cast‑iron valve body with tightly‑controlled valve‑hole tolerances, equipped with full set genuine seal components. Resist high‑pressure impact and hydraulic‑oil corrosion, tolerate sand and impurities, reduce valve‑bore scoring, internal leakage and oil leakage. Factory pressure‑calibrated without secondary adjustment. Adapt for long‑term heavy continuous site work and greatly lower early failure risk.
