In response to the requirements of low emissions (LDAR) and long-term operation, we design and manufacture stuffing box assemblies suitable for rotary valves and lift stem valves. We can provide multi-level sealing combinations including flexible graphite rings, reinforced PTFE, and spring energy storage seals, and optimize the gland structure and loading mechanism to ensure reliable sealing and low friction under conditions ranging from -200°C to 650°C and high pressure.
