Product Specifications

Technical details and manufacturing context for Control Solenoid Valve

Definition
A control solenoid valve is an electromechanical component within a reject mechanism that precisely regulates the flow of air or liquid to actuate rejection actions. It converts electrical signals into mechanical movement to open or close fluid pathways, enabling rapid and controlled rejection of defective items on production lines.
Working Principle
When an electrical current is applied to the solenoid coil, it generates a magnetic field that moves a plunger or armature. This mechanical movement either opens or closes the valve orifice, allowing or blocking fluid flow. When current is removed, a spring typically returns the valve to its default position.
