A safety valve follows a very simple mechanism to work.
Air compressor safety valve leaking.
If air leaks out the unloader when the pump stops replace the check valve because the check valve leaks air back towards the unloader.
In the latest instalment of gt air projects we show you how to change and service a check valve non return valve or one way valve on an air compressor.
If you find that your compressor pressure switch unloader valve is leaking air continuously then you have located at least one of the leaks on your air compressor.
Leaky gasket high pressure inlet valve.
Replace the safety valve if it leaks or pops open at normal operating pressure.
Air leaking from inter stage safety relief valve when compressor is pumping.
When the air compressor reaches the normal cut out pressure and stops but you notice while the air compressor is off that air is leaking out of a valve attached to or perhaps inside of the air compressor pressure switch.
The valve on the outside of the.
Replace the safety valve if it leaks air constantly.
Tighten fittings as needed and the leak is gone.
Remove and install new safety relief valve.
If using an air compressor in freezing temperatures check that the safety valves are positioned in a way that.
The safety valve pops open to relieve excessive air pressure if the pressure switch fails to shut off the air compressor at the cut out pressure setting.
Safety relief valve not functioning properly.
Ensure that the safety valves on your air tank are set to at least 10 or 15 psi whichever is greater above the operating pressure of the compressor but never higher than the air receiver s working pressure limit.
Whenever the pressure of your compressor is about to reach this maximum level the safety valve will relief air from the compressor so that the pressure drops.
If new safety valve leaks remove cylinder head inspect and clean reed valve assembly.
The safety valve pops open to relieve excessive air pressure if the pressure switch fails to shut off the air compressor at the cut out pressure setting.
Well if air continuously leaks out of the unloader valve then the compressor tank is emptying and the compressor needs to restart to replenish the air in the tank to get back up to cut out pressure so it can stop on its own.
Here is how it actually works there is a nozzle inside the valve.
Air continuously leaks out of the unloader valve on your air compressor and this is a problem.
