Solenoid valves Series CFB
2/2-way – Normally Closed (NC) and Normally Open (NO)
3/2-way – Normally Closed (NC)
3/2-way – Normally Closed (NC)
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.
