2-Way Slip-In Cartridge Valves Series C10C*E*The 2/2-way seat valves series C10C*E are equipped with an inductive switch to monitor the closed position. The poppet has a 60/40 area ratio (AA = 0.6 AC, AB = 0.4 AC) and is capable for flow in both directions. The safety overlap of the poppet avoids opening of the valve before the signal of the inductive switch has changed.
