What is a Solenoid Valve?
An electromagnetic actuator (solenoid) and a valve body make up a solenoid valve, which is an on/off electromechanically actuated valve. The valve actuator is the solenoid-plunger assembly, which opens and closes the valve. This actuator can be configured so that the plunger motion is limited to either opening or closing.
Types of Solenoid Valve Operations
The components of direct acting (direct operated) solenoid valves have a simple working principle. With no power, the plunger blocks the orifice with the valve seal for a normally closed valve. This closure is being forced by the arrival of a spring.

What is a solenoid valve?
A solenoid valve is a crucial component of any fluid control system. It is an electro-mechanical valve that is commonly employed to control the flow of liquid or gas which as a result, eradicates the need for an engineer to manually control the valve, saving time and money. Usually, solenoid valves are used whenever the flow of media has to be controlled automatically. An increasing amount of plants are taking advantage of the solenoid valve, as a variety of different designs are available, enabling the valve to be selected to suit the application in question. But how does a solenoid valve work? In this article, Linquip explains the solenoid valves working principle. Stay tuned to find out more.
When to use a direct acting solenoid valve?
Direct-acting solenoid valves are used when there is no line pressure applied. Typical applications would include a cleaning line when a pump supplies bursts of water through the line. A direct operated solenoid valve would remain closed, even when no pressure is being applied. This is in contrast to a pilot operated valve, which requires some pressure for the valve to stay closed.
What is a valve body?
The valve body is usually a special brass forging that is carefully checked and tested to ensure that there will be no leakage due to porosities. The armature, or plunger, is made from high-grade stainless steel.
How does a valve close?
The valve is opened or closed by the movement of the magnetic plunger.
Where is the armature in a two way valve?
The armature is located in the upper part of the valve. A stem passes through the fixed core and is coupled to the seal. This is held off the seal by means of a spring and makes a seal when the coil is energised, thus closing the valve.
Can a valve be reversed?
The inlet and outlet connections of the valve must not be reversed. The tightness of the valve depends to a degree on the pressure acting downward on the sealing disc. This pressure is possible only when the inlet is connected to the proper point as indicated on the valve.
What is a solenoid in a sprinkler system?
The solenoid is what controls the water pressure. It receives an electric current from the controller to determine what adjustments need to be made. It uses a plunger to adjust the valve, and there are a few more moving parts in the mix. All of this is what allows an automated sprinkler system to run things for you and provide that great convenience. But when the solenoid is bad, you can get some weird sprinkler problems.
How to diagnose a mechanical solenoid?
If the problem isn’t electrical, it’s mechanical. The best way for us to rapidly diagnose mechanical issues in the solenoid is to take a good look at the valve. Sometimes the problem is apparent, and we can get straight to it. In other cases, we might need to disassemble, clean, and inspect the inner components of the solenoid. This will give us a close look at everything and help us find the faulty part.
Why does my sprinkler keep running?
A problem with the plunger can prevent the solenoid from closing the valve when it’s time. That means your sprinklers will keep running after they’re supposed to stop. If you run into this problem, the first step is to turn off the water. If you can’t get it off at a local source, you can shut it off at the main.

What is an irrigation valve?
Irrigation valves are responsible for controlling the flow of water to the irrigation system. Most valves today are constructed out of a high quality industrial plastic or PVC. There is also the option to select them in a brass design in some instances.
How does a solenoid valve work?
The solution is a solenoid valve. A rubber diaphragm covers inflow and outflow ports keeping the valve closed. A tiny hole in the middle of the diaphragm allows water into an upper chamber. As long as the pressure is the same on both sides of the diaphragm, the valve remains closed. Inside that upper chamber, a small vent leads to the outflow side of the valve. A small plunger keeps that vent closed and the pressure equalized. When power is applied to the solenoid, an electromagnet lifts the plunger and water flows through the vent, decreasing the pressure above the diaphragm, which pulls it off the ports. Water flows through the ports, down the pipes and on to the sprinklers.
What is automatic irrigation valve?
Automatic irrigation valves allow homeowners to turn their sprinklers on and off unattended and without consideration--once the initial programming is done. The valves are controlled by a computerized controller or "clock" and are operated by safe, low-voltage AC power. They do their work in a very hostile environment.
What is the hole in the diaphragm of a valve?
A tiny hole in the middle of the diaphragm allows water into an upper chamber. As long as the pressure is the same on both sides of the diaphragm, the valve remains closed. Inside that upper chamber, a small vent leads to the outflow side of the valve. A small plunger keeps that vent closed and the pressure equalized.
How many volts does an irrigation controller use?
The irrigation controller tells the valve when to open and close. When the clock reaches the programmed time, 24 volts is applied to the lines running to the solenoid. The current is applied to the solenoid until the clock reaches the end of the programmed time.
How much pressure can a mechanical valve hold?
It would not be strong enough to open a mechanical valve capable of holding back 40 to 80 pounds per square inch (psi) of water pressure.
What is the solenoid in a valve?
The solenoid has a light spring loaded metal piston that , when the valve is closed, covers the inlet port hole. The surface area that the water comes in contact with on top of the diaphragm is greater than the surface area on the bottom of the diaphragm, so the valve stays closed until the water in the upper chamber is released.
Where does water enter a valve?
Water enters the valve from the system main line and exerts a force against the center of the valve’s diaphragm. A small orifice in the diaphragm allows the water to flow through to the upper chamber between the diaphragm and the bonnet.
