Introduce
2 way Solenoid valve is a key component widely used in situations where automatic fluid control is required. Guided by external electromagnetic signals, it directly controls the fluid medium and thus controls the drive of the actuator,It has the advantages of simple structure, rapid response, and precise control. In fields such as water treatment, healthcare, food, and chemical engineering, it often holds an irreplaceable and important position.
What is a 2 way Solenoid valve
What is a 3 2 way solenoid valve? We all know that it is a kind of using Electromagnetic drive,It has 3 ports and 2 working positions, and is a very common type of solenoid valve.Similarly,2-way solenoid valve is a type of solenoid valve with two ports, which has a simpler structure,but 2 way valve could adjust the throttle and liquid mixture medium.The 2-way solenoid valve has a clear logical structure and reliable control. It mainly realizes switch type control of fluids, electromagnetic drive, fast response, and can be installed in equipment with limited space. It has a long service life and low energy consumption.
The function of 2 way solenoid valve
A 2-way solenoid valve is the most basic type of solenoid valve, used primarily to control the start and stop of fluid flow. It has two ports—an inlet and an outlet—and operates by energizing or de-energizing the solenoid coil to open or close the valve, allowing or blocking gases or liquids.
main functions include:
Opening and closing flow paths: Quickly switches the valve to start or stop fluid flow.
Automation control: Works with electrical control systems for remote and automated fluid management, enhancing system efficiency.
Safety shutoff: Provides rapid shutoff of gas or liquid in emergency situations to protect equipment and personnel.
Energy efficiency and precise control: Controls flow accurately to minimize waste and improve process stability.
The types of 2 way solenoid valve
Classified by working methods
Direct acting
The valve core is directly driven by an electromagnet, with a simple structure and suitable for low flow and low pressure drop applications.
Pilot operated
Using a smaller electromagnetic force to control the main valve core through the pilot port is suitable for systems with larger flow rates and higher pressures.
Classified by work status
Normally Closed
When the valve is powered off, it closes; when powered on, it opens the air circuit.
Normally Open
When the valve is powered off, it opens; when powered on, it closes the gas path.

Additionally, 2-way solenoid valves can also be classified based on sealing materials, connection types, application fields, and other aspects.

The working principle of 2 way solenoid valve
The key components Of 2 way solenoid valve include Coil (Electromagnet),Plunger or Armature,Spring,Valve Body with Inlet/Outlet.
working principle
A 2-way solenoid valve uses an electromagnetic coil to open or close a flow path between two ports, providing directly on/off control of fluids in automated systems.
Power requirements
Advantages of DC power supply: fast response, small coil temperature rise, no electromagnetic noise; Advantages of AC power supply: No rectification required, convenient for long-distance transmission, but with higher electromagnetic noise.
2-way solenoid valves typically operate at DC 12V or AC 110V. 3-way solenoid valves generally have higher power requirements and commonly use DC 24V or AC 220V. Pneumatic solenoid valves come in various configurations, with DC 24V, AC 110V, or AC 220V being the most commonly used voltages.
2 way vs 3 way solenoid valve
2-Way Solenoid Valve:
Has two ports (inlet and outlet) and controls the flow by either allowing fluid to pass through or blocking it. It operates as a simple on/off valve, suitable for start/stop control of liquids or gases.
3-Way Solenoid Valve:
Has three ports and can direct the flow from one port to another or vent it to the atmosphere. It is typically used to switch between two different flow paths or to control the flow and exhaust in pneumatic systems.A 3-way solenoid valve not only controls the on/off flow of a fluid medium, but also enables switching or directional control, making it more suitable for use in automated control systems. A single 3-way valve can replace the function of multiple 2-way valves.
Overall, a 3-way solenoid valve is more versatile than a 2-way valve, capable of handling more complex operating conditions such as path switching, exhaust, and connecting or disconnecting multiple fluid lines. It is an ideal component for advanced automated control systems.
