Stainless steel solenoid valves
Series CFB
2/2-way - Normally Closed (NC)
3/2-way - Normally Closed (NC)
3/2-way - Normally Closed (NC)
Series CFB Stainless Steel direct acting solenoid valves for general purpose, 2/2-way and 3/2-way NC, are the ideal solution for a wide range of applications whereby the environment and fluids used can be particularly aggressive and contaminating.
Special versions are available on demand.
The valve function is determined by a poppet and the operation is direct.
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.
