Once they’ve fabricated the valve components, they assemble them. Manufacturers produce solenoid valves via a variety of processes, such as: CNC machining, laser welding, injection molding and coil winding. Today, much of valve fabrication and use innovation is focused on health and sustainability. Today, newer standards also restrict the use of hazardous substances in valve fabrication, so as to improve their environmental friendliness.

In the 1990s, governments around the world, as well as independent organizations, began creating solenoid valve standardizations, which enabled a higher frequency of international trade, easier collaborations between companies and easier maintenance. For instance, starting in the ‘70s, manufacturers began producing automatic shut-off solenoid valves, which were safer and easier to operate than manual control shut-off valves.

This trend of improvement continued on into the late 20th century. Miniature Solenoid Valves – International Polymer Solutions
