Vacuum applications
- We have thicker liners available for increased resistance to vacuum or for full vacuum applications
- Liner thickness varies from 3mm to 10mm depending on the size valve (3mm is default)
- To calculate the required liner thickness, we need to know the valve size 2-24” (DN 50-600), the temperature, and the amount of vacuum
Disc Liner Repair Kits*
- We offer inexpensive repair kits* as an alternative to replacing the entire valve.
- Kits* include all wear components: Disc, Liner, Backup Elastomers, Stem Seals, Gaskets, and Washers.
- * Repair kits are only available in the Americas. In Europe and Asia, individual parts can be ordered as needed.
