How To Clean Reed Valves On Air Compressor?

Reed valves are used in air compressors to control the flow of air. They are also known as orifice plates, check valves and butterfly valves. When they become dirty, they may not function properly and can cause damage to the compressor. This article will teach you how to clean Reed valves on an air compressor.

What Reed Valves are and what they do

Reed Valves are commonly found on air compressors and are used to control the airflow into and out of the compressor. When the valve is closed, less air can flow into the compressor, while when it is open, more air can flow in. This allows the compressor to operate at a consistent speed and prevent stalling.

Types of Reed Valves

There are a few different types of reed valves, each with its own specific cleaning requirements.

-Ball Valve: The simplest type of valve, a ball valve consists of a metal ball inside a brass or steel housing. To clean a ball valve, use a solvent such as acetone or denatured alcohol to dissolve the build-up on the ball and housing. Once the build-up is gone, scrub the surfaces with a stiff brush. Finally, dry the valve and housing thoroughly with a cloth.

-Check Valve: A check valve is similar to a ball valve, but features two sets of flanges that rotate around each other. To clean a check valve, first, remove the cover plate on the end of the valve body. Use a flathead screwdriver to pry off the old sealant and debris, then scrub the surfaces clean with acetone or denatured alcohol. Once all debris is gone, replace the sealant and reattach the cover plate.

-Diaphragm Valves: Most diaphragm valves feature several concentric rings that move in response to air pressure fluctuations. To clean diaphragm valves, first, remove the seat by unscrewing the bolt that holds it in place. Use a wire brush to remove loose dirt and debris, then re-install the seat and screw the bolt back in place. Finally, dry the valve and housing thoroughly with a cloth.

How to Clean Reed Valves on Air Compressor 

1. Open the air compressor and disconnect the power cord

2. Remove the cover on the compressor motor

3. Remove the screws that hold the fan in place and remove the fan

4. Disconnect the hoses from the motor, being careful not to strip them

5. Locate and remove the Reed valve (look for a metal frame with a rubber or plastic piece sealing one end)

6. Soak a rag in warm water and wring it out thoroughly. Apply rag to the valve and massage it around for about 10 minutes

7. Once the rag has been used, repeat steps 5-7 on another side of the valve

8. Replace valve, screws, fan, and cover9. Reconnect hoses and power cord
