Metal breathable valve is a device that allows gas to pass through while preventing liquid and solid particles from entering. It is widely used in harsh environments.
1. Material properties
Common metals: stainless steel (corrosion-resistant, high-temperature resistant), aluminum alloy (lightweight), copper alloy (good thermal conductivity), titanium alloy (high strength, corrosion-resistant).
Advantages: high temperature resistance (-50ºC to 500ºC), corrosion resistance (suitable for acid and alkali environment), high mechanical strength, long life.
2. Structural design
Porous structure: micropores are formed by sintering metal powder or laser drilling, with a pore size of 1-100 microns and a porosity of 30%-70%.
Multi-layer filtration: Combine different pore size layers to balance air permeability and filtration efficiency.
One-way valve design: Some models support one-way airflow to prevent backflow.
3. Performance parameters
Air permeability: 0.1-10 L/min·cm² (depending on the pressure difference and pore size).
Sealing level: IP67/IP68 (waterproof and dustproof), pressure resistance 0.1-10 MPa.
Chemical compatibility: Resistant to oil, solvents, etc., passed ASTM B117 salt spray test.
4. Manufacturing process
Sintering technology: Metal powder is sintered at high temperature to form uniform pores.
Precision machining: CNC or laser drilling ensures aperture accuracy, with an error of ±5μm.
5. Installation method
Interface type: threaded (M3-M20), , flange or welding, adapted to different equipment requirements.
Customized size: diameter 5mm to 50mm, thickness 1-10mm.
