Typically, the valve body is cast from high-grade grey cast iron (e.g., GG25 or EN-GJL-250) or ductile iron (e.g., GGG40), chosen for its excellent machinability, vibration damping characteristics, and pressure containment capabilities. Spools are commonly made from hardened steel alloys (e.g., 20CrMnTi, 40Cr) for superior wear resistance and strength, precision ground to achieve extremely tight tolerances.

Manufacturing Process Flow:

1. 1. Design & Simulation: Advanced CAD/CAE tools are used for initial design, fluid dynamics simulation, and structural analysis to optimize flow paths, minimize pressure drops, and ensure structural integrity under operational loads.
2. 2. Casting or Forging:
   • Casting: Molten iron is poured into molds to create the complex internal galleries and external form of the valve body. This method is cost-effective for intricate shapes.
   • Forging (less common for full monoblocks, but for components): For critical parts, forging can be used to improve material grain structure, enhancing strength and fatigue resistance.
3. 3. Machining (CNC): After casting, valve bodies undergo precise CNC (Computer Numerical Control) machining. This includes boring spool bores, drilling port connections, and milling mounting faces to achieve micron-level tolerances. Spools are also ground to a very fine surface finish to minimize friction and internal leakage.
4. 4. Deburring & Cleaning: Critical to remove any sharp edges or debris from the machining process that could impede operation or damage seals. Thorough cleaning removes contaminants.
5. 5. Surface Treatment: Depending on the application, surfaces might be treated for enhanced corrosion resistance (e.g., phosphating, zinc plating for valve body) or wear resistance (e.g., hard chrome plating for spools).
6. 6. Assembly: Skilled technicians assemble the valve components, including spools, springs, seals, and actuation mechanisms (e.g., levers, solenoids), ensuring proper alignment and functionality.
7. 7. Rigorous Testing: Every monoblock valve undergoes comprehensive functional and endurance testing.

Testing Standards & Service Life:

Valves are tested against international standards such as ISO 4411 (Hydraulic fluid power – Control components – Directional control valves – Mounting surfaces and porting), ISO 10770 (Hydraulic fluid power – Pressure-reducing valves), and ANSI B93.7.
