Background
Driven by carbon peaking, carbon neutrality and environmental policies, reusing complex wastewater containing heavy metals and resins from automotive painting and electrocoating is key to automakers’ green transformation.GRAT Quick-Opening Vacuum Valve feature reliable sealing, boosting system stability by 40% and cutting maintenance frequency by 90%, effectively supporting green automotive production.
Key challenge
- Insufficient corrosion resistance leading to easy failure: The pH value of the wastewater medium fluctuates greatly, making ordinary valves prone to corrosion, clogging, and reduced sealing performance;
- High risk of vacuum leakage: Ultrafiltration and reverse osmosis systems have high requirements for vacuum stability, and slight leakage will result in substandard water quality;
- Slow opening and closing response: Different types of wastewater require precise diversion, and slow response is likely to cause mixed discharge and reduce treatment efficiency.
