SV08-20 Normally closed cartridge solenoid valve is two way, two position cartridge style poppet type solenoid valve. The key parts of valve poppet and valve seat is manufactured by high strength steel materials and surface hardened before the last processing of fine grinding, therefore Finotek normally closed solenoid valve is longer service life than others.

When the solenoid normally closed cartridge solenoid valve is de- energized, the check valve produced in it is closed in one way, only the reverse flow is available to go through.  The flow allows to two way flow when the solenoid is energized. The solenoid coil transfers the input current into a magnetic field, then the electromagnetic armature elements in magnetic field change the magnetic force to pull or thrust force, with the force, valve poppet in the normally closed solenoid valve closes its flow channel in one way direction.
