A solenoid valve is used for controlling the flow of process media from one location to another. It is an electro-mechanical valve that can turn on or shut off the flow and can be used to control the flow of steam, air, water, oil, or other processes. An electric solenoid valve can be used alone or in tandem with other valves (like ball valves, for instance). One or more of these handy valves may be placed on a manifold with several control operations.

Solenoid Valves - Structure

The main parts of the valve are the solenoid and the valve. The solenoid controls the electromagnetic current that opens and closes the valve. The valve may have a soft or metal seat. A magnet is activated by the current to open the valve.

The Core

The core of the solenoid is enclosed in a tube with a dedicated solenoid coil. The core is the magnetic plunger that moves to open the valve when it is turned on. The spring holds the magnet in place when it is in the off position. (Please note: Since there are different types and sizes of for various applications, this is a simplified description).

A Plugnut

A plugnut prevents fluid from escaping when the solenoid valve is closed. An O-ring is used as a seal between the plugnut and the solenoid magnet. The materials and the seals must be compatible with the fluid flowing through them for full safety.

Different Forms of Electric Solenoid Valves

Metal, plastic, brass, stainless steel, and aluminum are the general materials used to build a typical solenoid valve. Most are two and three-way, but even four-way valves are available.

The valves come in all sizes, from miniature precision control units in various shapes to large push-pull, cartridge, and pilot valves. What's more, special rotary solenoids are available for industrial high-flow applications.

Solenoid Valve Applications

have many different uses as they are quite versatile. A solenoid valve may be used for water irrigation timer devices turning the water on and off for commercial building grounds.

In addition, solenoid valves are often used in various commercial water purifiers or even on pneumatically actuated valves to control the flow of air into the actuator to move (actuate) very large valves. Food processing plants use solenoid valves to control propane gas used for stoves and ranges, along with refrigeration systems and filling machines.

What's more, solenoid valves are used in washing machines and dishwashers so that the water flow can be properly controlled. They can control not only water but also air pressure, so they are often used in air conditioning systems.

Another useful application of solenoid valves is in car washes. They are applied so that wax and soap can be metered into a high-pressure pump. Apart from that, they can also help in controlling low-pressure features such as presoak, tire cleaner, or foam brush.

Interestingly, you can find those valves in automatic locking systems for door locks as well. On top of that, thanks to an electric pneumatic valve, it is easier to set the low or high pressure of a fluid and its flow direction in dental and medical equipment.

Industrial Applications

Industrial applications of solenoid valves include hydraulic and pneumatic systems that control steam, water, air, and other chemicals and can process liquids and gases. Moreover, special wet-pin pressurized bore solenoids are used in hydraulic drilling operations.

Apart from that, solenoid valves can also be found in industrial cleaning equipment. On top of that, explosion-proof solenoid valves are important for oil drilling, refineries, and mining operations.

The Main Benefits of an Electric Pneumatic Valve (Solenoid Valve)

Electric solenoid valves combine many different benefits for both your industrial process or plumbing company and your clients, so it is definitely a solution worth applying. Some of the most significant advantages include:

• Easy network connectivity
• Extremely quick open and close
• Simple, remote and energy-efficient operation
• Inexpensive replacement parts
• Great variety of solenoid valve applications
• Enhanced safety thanks to plugged external leakage and controllable internal leakage
• Compatibility with both DC and AC voltage
• Ability to be installed either vertically or horizontally
• Lightweight responsiveness

Electric Solenoid Valve FAQ

1. What is the solenoid valve price?
   The price of a solenoid valve can vary from one model to another. Some products can cost around $20, and some can cost over $1000, depending on their standard, materials used, possible applications, features, etc.
2. Is it a normally closed or normally open valve?
   An electric solenoid valve can be either normally open or closed. The first option means the valve can let in the flow without power, and the second option means the flow is stopped without power.
3. When should an electric solenoid valve be used?
   Solenoid valves should be installed in cases when it is necessary to control the flow of a gas or liquid, in either automatic control or on/off.
