BBNRV
Check valve
Main benefits
Sturdiness: manufactured from AISI316L stainless‐steel bar- Safety: it can be used to prevent water hammer
- Versatility: wide diaphragm opening to permit passage of solid particles
Description
Check valve BBNRV prevents fluid from flowing backwards. It ensures that fluid flows in only one direction.
It can be used to prevent water hammer.
Check valve opens when the pressure of the fluid exceeds the pressure applied by the spring. When the two pressures are compensated, the valve closes. A higher counter-pressure will ensure the valve closes.
Valve design is optimized for vertical position installation.
Standard features
- Connections from DN25 to DN100 (from 1/2” to 4”)
- EPDM, FKM, VMQ gaskets
- Maximum pressure 10 bar
