Why Ball Valves Need Regular On/Off Operations
Stainless steel ball valves are like door hinges; prolonged inactivity can easily lead to rust and jamming. Their core component is a ball with a through-hole, which controls water flow through 90-degree rotation. It is recommended to open and close the valve at least 1-2 times per quarter to ensure even wear of the sealing surface and prevent deformation due to prolonged pressure on one side. Increase the frequency of operation before the rainy season to prevent moisture from causing valve stem corrosion.
Maintenance Strategies for Different Scenarios
Household Main Inlet Valve: Operate once every six months, using silicone grease for maintenance.
Garden Irrigation System: Rotate once a month during off-seasons to prevent jamming.
Industrial Piping System: Maintain every 1-3 months depending on the medium characteristics.
Long-Term Backup Piping: Requires full opening/closing and rust prevention treatment.
Three Secrets to Extending Lifespan
Operating Technique: Slowly rotate to the fully open/fully closed position to avoid accelerated wear from a partially open state.
Environmental Management: Install rain covers on outdoor valves to reduce UV aging.
Preventative Maintenance: When increased rotation resistance is observed, promptly maintain the valve with food-grade lubricant.
