Solenoid valves are a simple and effective way to transfer electrical impulses into pneumatic operations. When power is applied to direct-acting solenoid valves, a magnetic field is created within the coil, attracting an internal armature and allowing air to flow through the ports.
A Solenoid Valve is an electromechanically driven valve component that controls the flow rate in fluid or air-powered mechanical systems. They’re used to control the flow of water, air, oil, and gas in various applications.
The usage of solenoids eliminates the need for an engineer to be physically present to manually operate a valve since they may be installed and utilised anywhere that gas or fluid flow has to be automatically controlled and monitored.
Here are four things to consider when choosing the right solenoid valves to help you make the best decision:
1. Material
Solenoid valves are available in various materials, including plastic, bronze, brass, stainless steel, and aluminium. Each substance has its advantages and disadvantages, so you’ll have to determine which is best for you.
When selecting solenoid valves, it’s essential to evaluate the material used in its construction and its compatibility with the media to be regulated.
Plastic is noted for its ability to tolerate a variety of media. If the medium is too hot, however, it performs badly.
Metal solenoid valves are excellent for hot fluids. Valve materials that are compatible with acidic or alkaline fluids are required.
2. Cost
The price of solenoid valves varies depending on the type and brand. The variances are caused by various factors, including the material utilised, valve type, valve supplier rates, etc.
Valve makers usually determine their prices, which might be high or low. The valve pricing you pick should be based on sufficient research and knowledge.
High prices indicate higher-quality materials that are also more durable. If you’re searching for a high-quality valve that can survive harsh circumstances and last a long time, this is the one to get.
If you only need a primary valve to control a little fluid, you may not need to spend much money on a solenoid valve. If expensive valves are required, such as when the valve has to be replaced, the advice is to go for them.
3. Operating Pressure
When choosing solenoid valves, it’s crucial to consider the system’s operating pressure. If the maximum pressure set exceeds, severe conditions might arise, and the valve may burst. It’s worth noting that maximum pressure is generally linked to a specific medium. As a result, various values can be assigned to gases and liquids. The minimal pressure differential between the in-out outlet is perhaps more critical.
4. Power Requirements
The power available to the device will assist in identifying the suitable solenoid for the pneumatic circuit. Keep in mind that the aperture of the valve restricts flow, and a larger size needs a greater power source to open.
Consider employing a pilot-controlled valve if you have a high flow need but a limited power source. A latching Solenoid Valve is an excellent choice if your power supply is restricted, such as if a battery powers your application.
Conclusion
Solenoid valves serve important functions, and selecting the proper one is essential. It ensures that the valve performs as expected, prevents damage to the valve body or coil, and guarantees that it is used safely.
The factors described here should assist you in making a more informed selection when purchasing a solenoid valve. Remember that only the suitable valve for your application will get your desired results.
