M&S 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.
Features
- Installation in vertical and horizontal pipelines
- Low pressure loss
- Reliable and robust design
- With unbreakable spring even with frequent operations
- With external marking for flow direction
- Between flanges type for easy disassembly even in rigid pipelines
- Special versions on request
- NRV MW with screwed-in O-ring in the valve disc (for use with high flow velocities or vacuum)
- NRV MW with double bearing of the valve shaft ( for hight switching frequency in horizontal installation)
