Long-running valves easily accumulate scale and rust. Regular cleaning is the most cost-effective maintenance for OUWEI valves.
🔧 External: wipe dust, remove rust and apply anti-corrosion paint
🔧 Internal: clean impurities to protect sealing surfaces
🔧 Lubrication: lubricate stems and bearings regularly
A clean and smooth OUWEI valve doubles its service life.
