Pneumatic valves use compressed air to open and close, and can be manually operated. They are designed for specific applications and can be customized. They are typically made of lightweight materials and are used in low pressure applications. Pneumatic valves are popular for supplying power to different parts of a machine and can control the speed and delicacy of the automation process.
In the field of mechanical automation, a pneumatic valve is used to create an automated flow through the opening and closing of the valve. A pneumatic valve uses compressed air, which causes it to open or close upon compression or release. Opening or closing depends on the mechanical design of the specific valve in the application using it. An air valve can also be manually operated by toggle switches or buttons that engage or reset to allow the machine user to control the amount of time the valve is opened or closed.
The design of a pneumatic valve typically depends on the application in which it will be used. Most of them, however, are built as online applications that don’t require manual operations. Pneumatic valves also come in many different shapes and forms and are often offered fully customizable in design to the specifics of the machine in which they are to be used. The amount of air used to operate them, as well as the amount of air released when they are deactivated, is all determined by the amount of air they need to perform their function.
Since most pneumatic valves are used in light or low pressure applications, such as small automated manufacturing machinery, most pneumatic valves are constructed with aluminum and plastic components. This allows the unit to remain lightweight while still being rugged enough to handle running over long periods of operation, which is a must in most automated manufacturing facilities. If required, a pneumatic valve can be made of any cast metal or alloy for use in more severe applications.
Technological and mechanical designs have led to such valves becoming popular as a means of supplying power to many different parts of a machine from one main air source. This has created the demand for many different types of pneumatic devices whereas in the past they were more often used in tools used in construction or mechanical engineering. Pneumatic valves offer the possibility of being fine-tuned in their operations. As such, they are able to control the speed of the automation process, as well as handle the more delicate operations with finesse.
