The Function Of An Air Check Valve

Air check valve is a vital component of any air compressor. It assists in preventing back draft by letting in air from the opposite side. At the same time, it prevents the air which flows in the reverse direction from back flowing out. Check valves are generally applied more frequently in air conditioner, heating system and in a cooling pump.


There are various makes and models of air check valve available in the market. Some of the widely used check valves are the following - PVC Plastic Water Pipe Connectors (PVC), SIP Tailpiece Connectors, Hose Clips, NPT Male Pipe Connectors, Kepa NPT Female Pipe Connectors, Metric Pipe Connectors and Metric Wall Pipe Connectors. All these serve for the purpose of regulating the pressure and flow of the gas from the inlet valve to the outlet hose. However, it is necessary to use proper installation for proper functioning of these fittings. Thus, proper guidance and precautions should be taken while installing them.


For proper working of an air check valve, it is necessary to ensure that there is proper connection between the two main bodies. These two bodies are the inlet valve and the outlet hose. When there is a proper connection, the outlet hose will form the valve for the air flow and vice versa. Thus, in order to have a safe and properly operating air compressor, you must ensure that both body parts are connected appropriately.


Installation of an air check valve can be easily done depending on the make and model of your air compressor. However, if you have not got proper guidance or instructions on how to install these valves, you can always take help from professional mechanics who are experienced in their making and use. If you are using a screw threaded type, you will have to drill into the cylinder's body. For removing the valve, you will have to do this procedure under the supervision of a professional.


For installing the air compressor check valves, the first thing that you have to do is to prepare the mounting platform. It is best if you can mount it on the wall. You can opt for any type of platform. However, mounting it on a surface that is not smooth can create backflow issues. In addition, installation on rough surfaces can impede proper valve circulation.


After mounting the valve, you have to set the backflow prevention device or BPN. This device functions like a gate that limits the flow of gas in one direction only. The way it works is by having a ring on the interior surface of the device that forms an 'X' figure. This figure marks the interior surface that is not passageway for gas flow.


In case the flow of gas in the other direction is unrestricted, the valve ring will be turned inside out thereby opening the valve. As soon as the valve is opened, a siphonic effect will take place and will cause the gas to go back up to the air filter.

Therefore, you have to open the valve again and repress the air flows coming in one direction only. Another option is to turn on the valve's emergency lock. This lock prevents the valve from being closed in the absence of an emergency.


When the pressure level is high, the air flows back up and the pipe gets pressurized. When the pressure level falls, the valve opens. This allows the gas flowing in one direction to push up against the walls of the pipe where the pressure level is zero. It will cause the valve to close and prevent any further gas flow. You can see that a lot of work lies behind understanding how an Air Check Valve works.
