Ita€™s our foremost priority that our system must be fully functioning system and if you have the same desire ita€™s necessary to use right products in your projects. Using the right pneumatic valves is essential for any project if you want to make it completely functioning. Before exploring the tips for selecting the right one, leta€™s discuss what are pneumatic valves? And what are the functions they performed?
Pneumatic valves are metal hollers that are filled with compressed air. They are the one component that is responsible for controlling pressure, rate and the amount of air when it passes through the pneumatic system. These systems are widely found in several industrial applications from diesel engines to pneumatic pressure power tools. These valves control the flow of air through the system and also regulate the amount and direction of the air pressure and air respectively.
Now below are some helpful tips to choose right one for your project and remember the wrong valve can cause the incorrect movement or sometimes not happen at all. Right valve that can be beneficial for your machine requires following things:
1. Firstly decide what you want whether to regulate the flow direction or flow speed. If you want to control the flow of direction you need directional control valve that controls the air flow direction or inhibit the all flow together whereas if you need to regulate the speed you need a proportional valve that controls the flow rate at which it flows down a given path.
2. Check out how many inputs and outputs you need that your directional valves have. Make a total of them that gives you an idea about how many openings you need to have. Normally there are three openings in common directional valves one for input and rest two for outputs. When one side moving piston would extend the piston then other would contract it.
3. Figure out how many switching positions you need. As we already discuss in above point there are two positions as one that extend the piston and other one which contract the piston. However you may have an application that need more switching positions but dona€™t forget that number of switching positions only control the number of options available for path the air can travel but does not control the flow. For controlling the flow, you need another valve.
4. In case you need more switching valves, you would select the valve that could handle the flow control in other way.
5. Determine valve inside pressure and make sure the selected valve can handle the pressure correctly. Remember the valve that could not handle the pressure break quickly and may become your expensive mistake.
