The drain valve allows you to discharge excessive moisture and depressurize the air tank for servicing. Always depressurize the air tank before servicing your air compressor. If you are unable to open the drain valve, discharge as much air as possible using an air chuck or blower nozzle.
The drain valve has to screw in as there is no other way to install it, save for welding it in. They usually use a high strength thread locker on the drain valves, so it may just be very very hard to remove. I would take a pipe cleaner saturated with oil and run around the inside of the drain valve and the screw portion of it.
Part 2 shows you step-by-step instruction to replace the faulty compressor drain valve. Although there are multiple possible failure points, I decided to check was the drain valve first because this drain valve uses a single compression O-ring to seal the air in. In the end, I decided to go with a ball valve type drain valve from Bostitch for reliability because I know ball valves are very durable and are not susceptible to heat damage like O-rings.
Your home air compressor – no matter how big or how small, how old or how new – has some form of drain valve. Air compressors are basically motors that pump air into a tank where the air accumulates and gains pressure. Once the water is flowing out, carefully tilt the air compressor so the drain valve is facing straight down.
how to remove air compressor drain valve Related Question:
What is the valve on the bottom of an air compressor?
What Is The Valve On The Bottom Of An Air Compressor? That little exit valve on the bottom of an air compressor is known as a drain valve. As you might expect it’s designed to drain stuff from the air compressor’s tank. What surprises many people is what you drain from the valve: water.
Should I store my air compressor with the drain valve open?
If unit will not be used for a while, it is best to leave drain valve open until such time as it is to be used. This will allow moisture to completely drain out and help prevent corrosion on the inside of tank.
How do you release pressure from air compressor?
The first step is to make sure your compressor is turned off. This could be unplugging it from the outlet or just making sure the switch is in the off position. Next, reduce the pressure in the tank to under 10 PSI. To release pressure, pull the ring on the ASME safety valve.
Where is the drain valve on an air compressor?
A condensate drain valve is a small device typically located at the bottom of a compressor’s air receiver. Whether the air compressor drain valve is open or closed determines if water flows out of or remains inside the compressor tank.
Where is the unloader valve on an air compressor?
Where Is the Unloader Valve Located? If you own a smaller reciprocating air compressor, you’ll likely find the unloader valve mounted on or inside the pressure switch. When the switch shuts the compressor off, it actuates the valve.
What is drain valve?
Drain valves remove media from process lines and process or storage tanks. They are used in applications such as compressed air systems where liquid, gas, or slurries need to drain or be drained from the system.
How does a compressor automatic drain valve work?
They work by allowing the condensate to gravity feed into the valves condensation reservoir. When the liquid in the reservoir rises to a point where the float lifts off the seats, control air pressure is sent to the pneumatic piston to open the normally closed ¾ ported ball valve.
What is pneumatic drain valve?
Condensate drains, or pneumatic drains, are a type of valve which is used to remove condensate from a pneumatic system. As the air cools within a system, the humidity within the air turns to condensate. It is important to remove condensate from an air system as water can cause damage and corrosion.
How often should you drain water from air compressor?
It is recommended that you drain your tank daily, whether it is manually or automatically. Water build up in your tank can cause the bottom of your tank to rust forcing you to invest in a new tank. If you find yourself forget about draining your tank, you should look into purchasing an electronic drain valve.
What are the two types of air tank drains?
Each air tank is equipped with a drain valve in the bottom. There are two types, manually-operated, by turning the quarter turn or by pulling a cable. You must drain the tanks yourself at the end of each day. And the truck equipped with an automatic drain, the water and oil is automatically expelled.
Is it OK to leave an air compressor pressurized?
Leaving an air compressor pressurized does not have any immediate bad effects. Most compressors are designed to tolerate pressurization for a day or two without the tank suffering a catastrophic failure. Doing so has a major drawback. A continuously pressurized tank will weaken its seal.
Should you release pressure on air compressor?
The short answer is yes, it is perfectly safe to leave an air compressor full. However, this assumes that it has been properly maintained, with regular draining to remove accumulated moisture from inside the tank.
How long can I leave air in my compressor?
Depending on the size and type of compressor, air compressors can be left running anywhere from a few hours to 24 hours a day, seven days a week.
Can air compressor explode?
Yes, air compressors can blow up. Air compressor explosions are most commonly caused by substantial corrosion of the compressor tank. Excessive condensation leads to corrosion, and you can avoid this outcome by monitoring and servicing the compressor and its auxiliary components.
Why is there water in my air compressor?
Water condensation is a natural occurrence and a byproduct of compressing air. The amount of water produced by an air compressor is largely dependent on the inlet condition, the quality of ambient air in a given environment, as well as pressure.
