What Are The Design Features And Surface Treatment Of Sanitary Valves?
Sanitary Valve refers to valves specially designed for industries with high requirements for sanitary conditions, such as food, pharmaceuticals, bioengineering, and cosmetics. So do you know the design features and surface treatment of sanitary valves?
Design features of sanitary valves:
Full-bore design: sanitary valves usually adopt full-bore design, that is, the channel inside the valve is the same as the pipeline, which avoids the retention of fluid inside the valve and reduces the possibility of residue accumulation.
No dead zone structure: All corners and gaps that may hide microorganisms are carefully designed as easy-to-clean arc transitions or tilt angles to prevent media from staying.
Quick-install interface: The use of sanitary quick-install connectors facilitates quick disassembly and assembly, saving time and manpower, while ensuring the tightness and sealing of the connection.
Self-draining structure: Some sanitary valves are designed with self-draining function, which can automatically discharge the internal residual liquid when the valve is closed to avoid cross contamination.
Visual window: Some valves are equipped with transparent windows, which can directly observe the working status inside the valve, which helps to detect abnormal problems in time.
Materials and surface treatment of sanitary valves:
Material selection: Most sanitary valves are made of 316L stainless steel or higher quality alloy materials, because these materials have excellent corrosion resistance and biocompatibility, and can resist the erosion of various chemicals and detergents.
Surface treatment: In order to reduce the chance of bacterial attachment and breeding, the surface of the sanitary valve is finely polished and electrolytically polished to achieve a mirror effect of Ra<0.8μm, making the surface extremely smooth, without dead corners and gaps, and easy to clean.
Sanitary valves follow strict hygiene standards in terms of material selection, surface treatment, structural design, etc. to ensure that there will be no contamination to the conveyed medium, while being easy to clean and.
