VLMS
Valve Leak Monitoring System
Foreign materials between the valve body and seat surface, damage from frequent valve operation, or cracks in the valve body, seat, stem, packing, or weld joints can cause valve leakage.
This system uses high-sensitivity acoustic sensors to monitor such leaks in real time, providing early leak information to prevent valve damage and improve efficiency through leak prevention.
