Pneumatic valve is an element responsible for controlling the rate, amount of air and pressure as it moves via a pneumatic
pump system. The pump’s system depends on the force of compressed air to move fluids through a piping system, and they can be used in multiple industrial applications ranging from diesel engines to various pressure power tools. Depending on a few components within the application and the type of pneumatic pump is used, many pneumatic valves can be found within the device, such as:
1) Two-Way Directional Valve
This valve passes air in two directions with the help of the ports which can either be closed or open. When open, air move from the first and second port or in the different direction. However, when closed, no air flows through the valve of a pneumatic pump.
2) Three-Way Directional Valve
This direction valve has three ports: one for connecting the valve to other devices. Second for connecting the air-flow and third one is to make an exhaust exit. These valves are usually used in pairs and connected to actuators or double-acting cylinders.
3)Four-Way Directional Valves
As the name suggests, it has four different ports. One makes an exhaust pathway, two of them are connected to actuators and the fourth one connected to a pressurised airflow. It is mostly used in providing dual pressure.
There are other directional valves as well that exist in a particular pneumatic pump like spring offset and resting state. Make use of the pumps best-fit to your requirements as per the valves.
