A Solenoid Valve is an electromechanically operated valve controlled by an electric current running through a solenoid coil. The main operation principle is to use the electromagnetic force provided by the solenoid to operate a plunger or a diaphragm, which, in turn, operates the valve.

When we refer to a”Solenoid Valve Closed Water,” we are specifically talking about a type of solenoid valve designed to control water flow. A “closed” solen” id val”e refers to its default position when not powered or energized. In the case of a normally closed solenoid valve, it will stay closed when no power is applied, preventing water flow. When electrically energized, the valve will open, allowing the flow.


Solenoid valves, especially those meant for water control, have various applications:

  • Home Appliances: Used in washing machines and dishwashers to control water intake.
  • Irrigation Systems: These valves control the water’s distribution in water systems.
  • Industrial Applications: Used in various industries to control water flow for cooling, processing, or cleaning purposes.

  • Plumbing Systems: Used in commercial buildings to control the water supply in response to specific triggers or sensors.

What Are They Used For?

Solenoid valves are often used for controlling high-pressure steam boiler feedwater systems. They can also be used for fuel metering, air conditioning, pneumatic controls, and hydraulic systems.

A solenoid valve is a type of three-way valve controlling the flow of liquids and gases. It uses an electromagnet to move a plunger inside the valve, which controls the opening and closing of one or both inlets to regulate fluid flow. The plunger is controlled by an electrical current, which causes it to change shape and either block or unblock its corresponding port. They are often used for controlling high-pressure steam boiler feedwater systems.

Applications of a water solenoid valve include regulating the flow of liquids and gases, controlling high-pressure steam boiler feedwater systems, fuel metering, air conditioning, and pneumatic controls.

A solenoid valve uses an electromagnet to change the shape of a plunger inside the valve, controlling the opening and closing of one or both inlets. The plunger is controlled by an electrical current, which either blocks or unblocks the corresponding port. When the current is turned off, the spring inside pushes the plunger back into its original position and closes the port.

Selecting a Solenoid Valve Closed Water:

  1. Material: Ensure that the valve is made of materials resistant to corrosion, especially for water applications. Common materials include brass or stainless steel.
  2. Voltage: The solenoid requires an electrical source. Ensure that the voltage requirement of the solenoid matches your supply.

How Do Solenoid Valves Work?

As we mentioned earlier, a solenoid valve is controlled by an electrical current. This current flows through the coil of wire around the plunger inside the valve, which creates a magnetic field. This, in turn, causes the plunger to change shape, unblocking or blocking the corresponding port as required. When the current is turned off, the spring inside the valve pushes the plunger back into its original position and closes the port.

What are the specifications of solenoid valves?

Solenoid valves are vital components in various applications, controlling the flow of liquids and gases in multiple systems. Their specifications are defined based on several parameters to ensure they function correctly and safely. Here are some standard specifications to consider when selecting a solenoid valve:

  1. Type of Operation:
    • Direct Acting: Uses a coil to move the valve plug directly.
    • Pilot Operated: Uses line pressure to open and close the valve.
    • Semi-Direct Operated: A combination of direct acting and pilot operated.
  2. The number of Ways and Positions:
    • 2-way: One inlet and one outlet.
    • 3-way: One inlet and two outlets or two inlets and one outlet.
