Non-return valves
M&S non-return valves are used in process engineering plants to prevent the flow reversal of fluids (liquids or gases) in pipelines.
For example, they prevent the liquid column in a riser pipe from flowing back if a feed pump fails. For dosing tasks or the merging of fluids, in the event of a pressure difference, penetration into the pipeline with the lower pressure is prevented.M&S non-return valves are available as between flanges type or screwed type.
Usage:
- To prevent the reversal of flow
- for liquids in rising pipes
- when combining liquid or gaseous media or dosing, especially with pressure differences in the pipelines.
- for liquids in rising pipes
- To prevent idling of pipelines or pumps.
