DIN Ball Check Valves (PN 10)
Ball Check Valves for horizontal or vertical installation reliably prevent the reverse flow of working medium. At the same time, they offer the least possible resistance in the direction of flow.
Materials:
- carbon steel
- stainless steel
Lining material:
- PTFE (virgin or conductive)
Other pressure levels:
- PN 16
- PN 25
- PN 40
Special features:
- earthing stud/lug
- vent hole extension
Optional extras:
- final painting
- non-destructive testing
