One-way exhaust valve and one-way drain valve

The one-way vent valve and the one-way drain valve are proprietary products developed in-house. They share the same appearance and dimensions, differing only in their internal components.

One-way valves can vent gases and condensate from inside the package while effectively preventing external gases from entering, thereby stabilizing the internal environment and ensuring that the anti‑rust product delivers optimal corrosion‑prevention performance.
