Solenoid water and air control valve
Solenoid valves are electromechanical devices widely used to control the flow of liquids or gases. They consist of a solenoid (an electromagnet) and a valve body. When an electric current passes through the solenoid coil, it creates a magnetic field that moves a plunger or armature, which in turn opens or closes the valve.
Solenoid Water and Air Control Valves:
- Normally Closed (NC): When power is applied, the solenoid energizes, opens the valve, and allows flow. This is the most common type.
- Normally Open (NO): The valve is open (allowing flow) when the coil is de-energized. When power is applied, the solenoid energizes, closes the valve, and stops flow.
- 2-way, 3-way, 4-way: Refers to the number of ports and flow paths.
- 2-way: One inlet, one outlet (simple on/off control).
- 3-way: One inlet, two outlets, or two inlets, one outlet
- 4-way: Two inlets, two outlets (typically for controlling double-acting pneumatic or hydraulic cylinders).
