Stem Packing. The design of the V-shaped packing in the GKV75/76 series can automatically adjust and seal in both directions to prevent foreign matter from entering the upper stem cavity. The packing can also be adjusted externally, has good function, is suitable for vacuum applications, and provides a tertiary sealing effect in critical situations.
Geko's unique tongue and groove joint valve seat design can completely isolate the medium in the valve body and the pipeline. The flexible torque of the resilient valve seat is lower than that of many valves on the market, especially suitable for most vacuum conditions.
