Valves
Valves and precision fluid fittings are the core of reliable fluid control systems. Our high-precision CNC turned and milled components deliver superior sealing integrity, zero leakage, and stable pressure regulation under demanding operating conditions.
| Core Machined Components | Materials | Key Machining Parameters | Application Value |
|---|---|---|---|
| Precision Valve Spool & Sleeves | Stainless Steel 316L / Brass / Titanium Alloy | Dimensional Tolerance: ±0.002 mm Surface Roughness: Ra 0.1 µm Cylindricity: ≤0.001 mm | Ensures smooth sliding, zero fluid leakage, and precise flow control under high pressure. |
| Quick-Disconnect Couplings | Stainless Steel 304/316L / Aluminum 6061-T6 | Thread Tolerance: 6g/6H Concentricity: ≤0.003 mm Sealing Groove Ra: 0.2 µm | Provides instant, leak-free connection with reliable seal engagement and high vibration resistance. |
| Hose Barb Fittings | Stainless Steel 316L / Brass / PEEK | Barb Profile Precision: ±0.005 mm Burr-Free Edge Condition Passivated Finish | Prevents hose slippage and fluid contamination in chemical, medical, and liquid cooling systems. |
Machining Process and Quality Inspection Standards
Process Solution: Multi-axis CNC mill-turn machining and precision Swiss turning enable high-concentricity one-time forming. Key sealing surfaces and threads are processed by CNC grinding and micro-polishing for stable precision.
Quality Inspection Requirements: 100% inspection of key dimensions with Coordinate Measuring Machine (CMM); pressure test for sealing performance ≥10 MPa; defect rate controlled below 0.3%.
Working Condition Adaptability: Machined parts can withstand high and low temperature environments ranging from -40°C to +200°C, suitable for medical, semiconductor, and industrial fluid control applications.
