Many different applications require the use of a solenoid valve. This is a valve that is electromechanically operated. In other words, it relies on an electrical current passing through a solenoid activate or deactivate the valve.
There are two basic options in solenoid valves. One is a two-port valve that will turn on and off to control flow. The other option is a three-port valve where the solenoid functions to direct or switch the flow through the valve to one of the two outlet ports. It is also possible to group solenoid valves to provide more than just two port options for more complex systems.
While some of the common solenoid valves are made of brass, aluminum or stainless steel, there is also the need for chemical resistant solenoid valves in many industries and applications. These are typically made from PTFE (polytetrafluoroethylene) on the wetted surfaces to ensure years of use without concerns about damage by the fluids in the system, regardless of their chemical composition.
Extreme Conditions
The chemical resistant solenoid valves come in a range of sizes including miniature and subminiature options. These valves are designed to work with a variety of different flow materials through a system and offer full corrosion resistance. This can also include utilizing these valves where system fluid temperatures, as well as valve temperatures, may be very high or very low.
Choosing the correct type of valve will be essential, as well determining the ideal configuration. In many cases, Original Equipment Manufacturers will find standard designs are the best option. There are also specialized companies that provide custom designs of chemical resistant solenoid valves to suit a specific application, which provides greater freedom in design and system configuration.
When considering solenoid valves for these types of applications, always ensure full compatibility with the material, system requirements as well as with the type of seal design.
