Upper Sealing Devices: The Silent Guardians of Valve Reliability In industrial production, valves act as the “gatekeepers” of pipeline systems, precisely controlling the flow of fluids. Among their many components, sealing performance has always been a critical concern for engineers. One element in particular—the upper sealing device—plays an irreplaceable role in...

How to Determine If Valve Packing Needs Replacement In industrial production, valves are critical components for controlling fluid flow, and the packing gland is central to valve sealing. When the packing fails, media leakage may occur—compromising production efficiency, creating safety hazards, and even causing environmental issues. Timely assessment and replacement of valve packing are...
