How Pneumatic Valves Work
Pneumatic systems provide a fine degree of control, allowing force to be applied where it’s needed, when it’s needed and in the amount needed. Pneumatic valves help by creating proper air pressure and flow rates.
Pneumatic flow control and needle valves regulate the flow of compressed air. Mechanically or manually operated directional control valves allow flexibility of the pneumatic working ports. This provides a practical solution for a variety of different requirements to support multiple solenoid valves. Solenoid valves rely on electromagnetic levers for controlling airflow and release to achieve proper compressor function.
Pneumatic products are very lightweight and compact in size for the amount of power they produce. Portable units can be used with less operator fatigue, while stationary units can be mounted in confined spaces.
Most pneumatic devices can be instantly reversed without damage to the equipment. In many cases, this can reduce the cycle time of the equipment and speed production.
Pneumatic threshold sensors detect the end of an air cylinder stroke and signal when pressure drops. The check valve, or non-return valve, allows airflow in one direction. In the event of loss of pressure or a sudden shut down of the system, piloted non-return valves stop air cylinder movement as needed and maintain loads. Circuitry valves, such as speed controls, adjust the stroke speed of air cylinders and actuators.
