Solenoid valve with small valve seat DN 0.5mm to max. DN 1.2 mm for high internal pressures. The max. possible pressure depends on the nominal width! The valve is closed in the rest position by spring force (NC). The energised solenoid pulls the solenoid armature against the force of the spring to the counter core. The valve opens. Valves of this type do not require differential pressure. The valve only seals and can be shut off in the direction of the arrow. Due to the small seat nozzles, it is recommended to install a fine filter 0.04mm directly upstream of the valve.
