Many tools and machines nowadays utilise systems that will allow them to operate. One popular system that many tools and machines use is the pneumatic system.
Pneumatic systems are used in tools and machines as they regulate the amount of air, the rates, and the pressure on which the air moves through them. With the regulation of compressed air, things that run on pneumatic systems can operate for a long time. They are likewise durable, reliable, safe, and secure. All these benefits and functions, however, can only be possible if the components of pneumatic systems are in good condition. One of the components that these systems should possess is the pneumatic valves.
Pneumatic valves block and divert the compressed air flow within pneumatic systems. They generally drive the operation of the actuator, gripper, and other similar things. To date, there are three general types of pneumatic valves that business owners like you should know.
Two-way directional valves are comprised of two ports connected with a passage. The passage of these valves can be opened or closed to regulate the flow of compressed air. The airflow regulation is done by an electrically activated solenoid, which is designed to shift the valve spool or poppet. Once the valve ports are closed, the compressed air will not be able to flow. Air, alternatively, can move through the ports once they are open. These valves have an easy on-off function to interlock, isolate, and connect different system components.
2. Three-Way Directional Valves
Three-way directional valves have three ports connected through passages in a valve body. One of the ports serves as the exhaust exit, while the other one is connected to airflow. The last port is designed to connect the valve to a device like an actuator. Once two of the three ports have been opened, the remaining one will remain closed. During this time, the compressed air will move to the device. The exhaust is then expected to be vented when two different valves have been opened. These valves can be maximised in double-acting cylinders and work with high cyclic applications.
3. Four-Way Directional Valves
Four-way directional valves have four different ports. The first port is designed to be the exhaust pathway of the valves. The second port, alternatively, connects to an airflow that is pressurised. The third and fourth ports, ultimately, are attached to the actuators. What is great about these valves is they can conveniently reverse the motion of cylinders and motors.
