Solenoid valves are used in a wide variety of places, from controlling gas and steam pressure inside industrial machines and boilers, to controlling water flow in boat engines, and in many other places. Gas solenoid valves are specifically used to regulate the flow of gas through a pipe, such as in many gas heaters and other heating appliances. Although many people expect to see solenoid valves used in industrial applications, they may be surprised to find out how many smaller appliances and tools also use gas solenoid valves and other solenoid valves in their operations.

One unusual place to find a solenoid valve is in a coffee machine. However, some coffee machines use the valves to control the water or steam flow inside the machine. Solenoid valve companies have specifically manufactured solenoid valves for use in coffee makers for both commercial and home use. The valves control the flow of the water, steam, and cleaning applications of the machine in a precise and specific manner. This high level of precision is ideal for producing delicate coffee with intense flavor every time. The solenoid valve can produce the same standard of excellence with every brew because of the precise nature of the valve.

The valve is pre-programmed to output a specific amount of water, steam, or cleaner through the valve, which settings can vary depending on the settings the user programs into the machine. Using a precise solenoid valve increases the quality of the brew and also prevents the unit from receiving common problems, like leaks, or in rare cases, explosions for too much steam in the unit. Specialized solenoid valves for coffee makers also contain special mineral-resistant materials that help prevent the unwanted build-up of mineral deposits on the interior of the valve or other parts of the coffee machine.
