Normally closed solenoid valve

Normally closed solenoid valve

●The Normally closed solenoid valve consists of a solenoid coil, an armature, a valve body, a spring, and a valve seat. The solenoid coil is the power - generating component. When energized, it creates a magnetic field that attracts the armature. The spring is responsible for returning the valve to its closed position when the power is off. The valve body provides a passage for fluid, and the valve seat ensures a tight seal when the valve is closed.

●In the de - energized state, the spring force keeps the valve closed, blocking the fluid path. When an electrical signal is sent to the solenoid coil, the electromagnetic force generated overcomes the spring force. The armature moves, opening the valve and enabling fluid to flow through the valve body from the inlet to the outlet. Once the power is cut off, the spring forces the armature back to its original position, closing the valve.●In the de - energized state, the spring force keeps the valve closed, blocking the fluid path.
