Series CFB
solenoid valves
2/2-way - Normally Closed (NC) and Normally Open (NO)
3/2-way - Normally Closed (NC) and Normally Open (NO)
Series CFB solenoid valves for general purpose are available in the NC and NO version,
2/2 and 3/2-way.
Special versions are available on demand for the protection against the water hammer or
with specific traitments for the interception of aggressive fluids.
The valve function is determined by a
poppet or by a diaphragm with operation
direct or indirect.
Different versions are available according
to the nominal diameter and to the threaded
ports, as shown in the following tables. They
can thus satisfy various requirements in
terms of flow rates and working pressures.
