A Solenoid Valve is an electromechanically operated valve used to automatically control the direction, start or stop of fluid or pneumatic flow.
When an electrical signal is applied to the solenoid coil, the valve changes position, directing the media through the appropriate ports. When the electrical signal is removed, the valve returns or switches position according to its specific configuration.
The pictured unit is a pneumatic directional solenoid valve and appears to be a 5-port valve, commonly used for controlling pneumatic actuators and other compressed-air equipment.
From the markings visible in your photograph, this particular unit has a 24 V DC solenoid coil and a marked operating pressure range of 2–10 kgf/cm². I would treat those as specifications of the pictured model rather than specifications for Invincible’s entire solenoid-valve range.
