When it comes to selecting the right types of air valves for any application, many options may be at your disposal to consider as your valve in your plumbing project. It is also wise to note that each valve has its specification and application, and picking any model for a different task may ruin the whole project. Therefore, it is helpful to understand the differences and choose the best- suited for your requirements. The following factors will help one arrive at the valve type right for your pneumatic application.
Media
You should always ask yourself what gas or liquid will be controlled by the valve you are looking for or the valve you are buying. You should also find out the pressure drop and the gas or liquid input pressure under transit. With the ideas from the total pressure applied at the input and the fluid’s nature under the transit, you can choose an air valve customized for your specifications. You can also involve the shop attendant to help you pick the right valve. This is essential as it gives one first-hand information on the liquid action due to the pressure inputs.
Valve Actuation method
There are a variety of ways available to open and close the pneumatic valve. The most known methods are solenoid operated, manually operated, mechanically operated, and remote air operated. Assess your project well and pick the valve actuation method that you can afford or trust while keeping in mind the nature of the fluid you control.
Valve configuration
Most pneumatic directional control valves are 2-way, 3-way, or 4-way, and as a rule, it accounts for their active media ports. It is wise to assess the valve configuration well suited for your valve project requirements before choosing an air valve in the market.
Flow capacity (Valve size)
A little valve will slow down the fill time or cause other inefficiencies in the system, while an oversized valve can be classified as a form of waste in the system. It is always important to estimate your intended application’s maximum flow capacity and select the valve size with enough power.
Cost of the valve
The application that requires more significant pressure drop and input pressure may require a full valve that may have some added components to deliver the pressure needed; therefore, the valve’s cost will be higher. It would be best if you also were assured that the valve would be more durable and reliable.
Conclusion
Once you have used the factors mentioned above to identify the type of valve you need, you should weigh specific performance and integration attributes of matching models and brands available from the valve manufacturers.
