The core advantage of this high-precision water cap is its ultra-narrow 0.2mm slots, processed via micro-laser cutting technology with a tolerance of ±0.01mm. This precision ensures that even 0.2μm filter media particles are retained, preventing media loss that could damage RO membranes or reduce filtration efficiency. Its 316L stainless steel construction provides superior resistance to high-temperature water and chemical cleaning agents, making it suitable for RO pre-treatment systems that require frequent chemical backwashing. The cap’s M30×1.5 threaded connection ensures a secure fit, withstanding maximum working pressures of up to 1.6MPa without loosening. With an impact resistance of ≥10J, it resists damage from filter media expansion during backwashing, and its 1.5m³/h rated flow rate meets the demands of high-throughput filtration systems.
This slot-type stainless steel water cap has a cap body height of 60mm, with a 55mm diameter and an M30×1.5 threaded handle, fitting standard high-precision filtration system water distribution plates. The cap body is forged from 316L stainless steel, with a wall thickness of 2mm to ensure high-pressure resistance. It features 72 micro-slots evenly distributed on the cap body and top, providing a total filtration area of 0.008㎡ to ensure uniform water flow across the filter bed. The product has a maximum working pressure of 1.6MPa and a working temperature range of -15℃ to 140℃, adapting to high-temperature industrial water treatment systems and chemical cleaning processes. Its equivalent filtration precision is 0.2μm, and it has an impact resistance rating of ≥10J, ensuring durability during backwashing cycles. The surface is passivated to enhance corrosion resistance.
This high-precision water cap is primarily used in advanced water treatment systems, including RO pre-treatment filters, UF equipment, and pharmaceutical-grade water purification systems. In RO pre-treatment systems, its ultra-fine filtration prevents fine filter media particles from entering RO membranes, extending membrane service life by 30% and reducing replacement costs. In pharmaceutical water purification, its 316L stainless steel material and high precision ensure effluent meets USP Class I water standards. In industrial high-pressure filtration systems, its 1.6MPa pressure resistance withstands high operating pressures without deformation. Additionally, it can be applied in electronic-grade water production systems and seawater desalination pre-treatment, providing reliable high-precision water distribution for critical water treatment processes.
