Air Compressor Safety Valve Leaking

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.

Air compressor safety valve leaking. The valve on the outside of the. A safety valve follows a very simple mechanism to work. Air leaking from inter stage safety relief valve when compressor is pumping. Unloader valve is leaking air.

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. Replace the safety valve if it leaks air constantly. Remove and install new safety relief valve. Leaky gasket high pressure inlet valve.

If using an air compressor in freezing temperatures check that the safety valves are positioned in a way that. Air continuously leaks out of the unloader valve on your air compressor and this is a problem. 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 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.

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 air leaks out the unloader when the pump stops replace the check valve because the check valve leaks air back towards the unloader. 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.

Here is how it actually works there is a nozzle inside the valve. Tighten fittings as needed and the leak is gone. Safety relief valve not functioning properly. With the compressor off the unloader valve should not be leaking any air at all after the unloading process a second or two has completed.

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.
