Product Description
Premium KMX36NA hydraulic distribution valve for 70–90 ton excavators, Kawasaki KMX series main control valve with load sensing, low pressure drop, OEM‑equivalent quality, global wholesale.
Working Principle
- Central flow distribution hub: Receives high‑pressure oil from dual main pumps and routes it to all working circuits.
- Pilot signal control: Pilot pressure shifts spools to adjust flow direction and speed.
- Load‑sensing feedback: LS shuttle valve detects load pressure and signals pumps for on‑demand supply.
- Pressure protection: Main relief valve limits max pressure to 34.3 MPa, protecting components.
- Multi‑function coordination: Pressure compensation ensures smooth simultaneous operation of multiple actuators.
- Flow regeneration: Recirculates return oil to boost speed and save energy.
Production Process
- Raw material inspection: High‑grade cast iron with certified chemical composition.
- Precision casting: Resin‑bonded sand mold for dense, defect‑free body.
- Stress relief annealing: Eliminates casting stress to prevent deformation.
- 5‑axis CNC machining: Bores, spools, and ports machined to ±0.02 mm tolerance.
- Spool hardening & chrome plating: HRC 58–62 + hard chrome for wear resistance.
- Hydraulic assembly & calibration: Load‑sensing and pressure compensation parameters fine‑tuned.
- 38 MPa pressure test: 15‑minute hold to screen leakage risks.
- Ultrasonic cleaning & anti‑rust packaging: Sealed bag + wooden crate for export.
