Custom Valve Manifold Block Manufacturer
Valve Manifold Block
China Simis Company specializes in the custom manufacturing of Manifold Blocks and Valve Blocks characterized by highly complex internal flow paths. These components integrate multiple valves into a single compact unit, reducing plumbing complexity, minimizing leak points, and improving overall system response. We move beyond simple cross-drilling to provide integrated fluidic solutions with curved and multi-level internal channels.
To ensure performance under extreme pressures, we utilize a multi-process manufacturing approach: Ductile Iron and Steel Casting for heavy-duty industrial blocks, Aluminum Gravity Die Casting for lightweight mobile applications.By utilizing Shell Mold Casting, Lost Foam Casting (LFC) and Investment Casting, we can create "un-drillable" internal geometries that optimize flow efficiency and significantly reduce the overall footprint of the block. For ultra-high-pressure applications, we combine Multi-Axis CNC Deep-Hole Machining with specialized deburring to ensure every intersection is surgically clean.
What Manufacturing Processes Are Applied to Valve & Manifold Blocks?
Our company primarily casts manifold blocks and valve blocks with highly complex internal flow channels. For simple channel hydraulic valve blocks, solid blanks can be used via Precision CNC machining.
| Manufacturing Process | Component Focus | Material Focus | Key Advantage for Fluid Performance |
| Lost Foam Casting (LFC) | Complex manifolds with intricate internal cross-drilled channels and ports. | Ductile Iron, Gray Iron. | Internal Complexity. Enables the casting of complex internal flow paths that are difficult or impossible to drill, reducing fluid turbulence. |
| Shell Mold Casting | Consistent production of medium-sized valve bodies and control blocks. | Ductile Iron, Carbon Steel. | Superior Surface Quality. Provides smoother internal casting surfaces than sand casting, reducing flow friction and contamination risks. |
| Gravity Die Casting | Lightweight manifold blocks for automotive and mobile hydraulics. | Aluminum Alloy. | Pressure Tightness. Provides a much denser grain structure than high-pressure die casting, ensuring the block is oil-tight under pressure. |
| Sand Casting (Resin Sand) | Massive industrial manifold blocks for heavy presses and marine systems. | Ductile Iron, Gray Iron. | Robustness for Large Units. The most economical method for manufacturing large-scale blocks with significant wall thicknesses. |
| Investment Casting (Lost Wax) | Small, highly intricate valve blocks with integrated mounting features. | Stainless Steel, Alloy Steel. | Near-Net Shape Precision. Reduces the need for extensive secondary machining while providing excellent corrosion resistance. |
| Deep Hole Drilling & Deburring | All manifold types requiring internal porting. | All Metals. | Clean Flow Paths. Specialized CNC cross-drilling and thermal deburring ensure no burrs remain to damage sensitive valve spools. |
How to Select Materials for Valve & Manifold Blocks?
Choose the appropriate material based on the different usage environments to save economic costs while ensuring that the conditions are met.
| Material Type | Core Performance Attributes | Primary Manifold Application |
| Ductile Iron | High Strength & Excellent Machinability. Resists "ballooning" under pressure. | Industrial Hydraulic Manifolds, agricultural control blocks. |
| Alloy Steel / Carbon Steel | Ultimate Pressure Resistance. Can be hardened for wear-prone valve seats. | High-Pressure Systems (350+ Bar), oil & gas control valves. |
| Aluminum Alloy | Lightweight & High Thermal Conductivity. | Mobile Hydraulics, aerospace valve blocks, and automotive braking systems. |
| Stainless Steel | Maximum Corrosion Resistance. Ideal for aggressive fluids. | Marine Hydraulics, chemical processing, and food industry manifolds. |
What Quality Control Measures Are Adopted for Valve & Manifold Block Complex Channels?
The more complex the internal path, the more rigorous the inspection must be:
·Endoscopic Inspection (Borescope):
Visual verification of every internal intersection and channel surface to ensure they are burr-free and smooth.
·Hydrostatic Pressure Testing:
Validating structural integrity between adjacent channels to prevent internal cross-talk/leakage.
·Helium Leak Testing:
For high-purity or gas manifolds requiring absolute hermetic sealing.
·Flow Bench Testing:
Measuring actual pressure drop across the block to verify it meets CFD (Computational Fluid Dynamics) simulations.
·Ultrasonic / X-Ray Inspection:
Ensuring the casting or billet is free from internal inclusions or porosity that could fail under pressure.
·Cleanliness Verification:
Utilizing specialized flushing and particle counting to ensure internal channels are free of debris.
·Coordinate Measuring Machine (CMM):
Verifying the precise location and depth of every valve cavity and port.
