Solenoid valves are a very versatile and useful control component that can be used in an almost endless variety of applications, industries, and processes. This is due to the fact that they automatically control gas and liquid flow, without having to be manually operated by an engineer.

 

The main thing to keep in mind when buying a solenoid valve is that it must be able to operate in an environment free of solid particles. For this reason, stainless steel is the ideal material of choice for this type of valve.
There are also other important factors that you must consider before deciding to buy one of these. These include the nature of the fluid that will be regulating the flow as well as its temperature and pressure.

 

Direct-acting Valve
Direct-acting solenoid valves are a very simple type of solenoid that is designed to open or close by means of electromagnetic activity in the coil. These types of valves are typically favored over pilot operated valves because they don’t require any external pressure to operate and they open or close very quickly.
This type of valve is also very cost-effective and a lot easier to maintain as it can run on low power. They are usually very durable and tend to have a much longer life cycle than pilot operated valves.

 

Pilot Operated Solenoid Valves
There are two main types of pilot operated solenoids: internally piloted and external piloted. Internally piloted valves are a great solution for larger pipeline systems, as they can be actuated by pressure differentials that are able to do the majority of the work in opening and closing the device.
