Here’s When A Standard Pneumatic Valve Will Do No GoodJune 19, 2016
What to Do In The Event Of a Valve Shutdown?October 8, 2016
What are they used for? An essential and necessary component, valves are specifically used to control a fluid’s flow rate, pressure, and direction.
Pneumatic controlled valves are different. This device controls the direction of pressurized air, which is important for the system’s efficiency and success.
We discuss how different pneumatic controlled valves are in the following:
Pressure Relief Valves
Pneumatic valves help release extra pressure from the system, which is why they are also called safety valves. They prevent the system from bursting. The inlet port, designed on the valve specifically for this purpose, is responsible for releasing pressure into the atmosphere. Pressure relief valves are typically found in air storage devices.
Flow Control & Directional Control Valves
Flow control valves are the most commonly found types in pneumatic systems and applications. Available in two configurations, these valves can be used in two different ways!
It’s a variable restriction, outfitted with a component that controls, i.e. opens or closes the valve. An example of this configuration type is needle valve.
This type of valve also controls the direction of liquid flow, but only in one direction. The valve restricts flow in the opposite direction, like what the check valve does.
Directional valves of many sizes, styles or configurations are also featured in pneumatic systems. The type of valve required for a particular application depends on the operational level of the application, i.e. check valves for simple applications.
Other Considerations for Pneumatic Valves
The following will help you choose the best pneumatic valve for your required application:
- Directional valves can be found both in standard and non-standard mounting configurations
- Non-standard configuration is designed according to the manufacturer’s notions
- Different manufacturers will offer different features and valve specifications
- Proper research must be conducted before choosing a non standard directional pneumatic valve
Additionally, you can find standardized valves in the market that will suit more than one specification. Look for a pneumatic valve manufacturer that fits all applications and their different specification requirements.
