Overview

Hydraulic valve bodies feature complex cross oil galleries, deep blind holes, threaded holes and precision mating surfaces. Residual machining chips, casting sand, sintered hydraulic oil, carbon deposits and grinding dust can easily cause valve jamming, system leakage and hydraulic failure. Sinobakr provides customized high-precision cleaning solutions for cast iron and aluminum valve bodies, fully meeting VDA 19, ISO 16232 and national hydraulic component cleanliness standards, achieving zero residue, zero watermarks and zero corrosion for mass production and overhaul maintenance.

Applicable Workpieces

Multi-way valve bodies, servo valve bodies, hydraulic manifold blocks, stack valves, proportional valve bodies, aluminum hydraulic valve assemblies and engineering machinery valve cores.

1. CNC High-Pressure Jet Cleaning Solution (For Heavy-Duty & Complex Oil Duct Valve Bodies)

Application Scenarios

Suitable for cast iron valve bodies and large hydraulic manifolds with heavy oil sludge, deep blind holes and cross passages after machining or long-term operation.

Core Equipment

Sinobakr BK-CNC Series Intelligent High-Pressure Cleaning Center

Process Principle

Adopts multi-axis CNC programmable positioning, matching custom fixed-point rotary nozzles. It performs directional high-pressure jet flushing for dead corners, deep holes and intersecting oil galleries that cannot be cleaned manually, thoroughly removing iron chips, aluminum chips, aging hydraulic oil and carbon deposits.

Standard Process

Hole protection & plugging → High-pressure rough washing of outer surface → CNC fixed-point jet cleaning for internal oil passages → Multi-stage circulating rinsing → Hot air closed-loop drying → Cleanliness sampling inspection
