Air pressure valves are valves which maintain pressure of air in the system in which the valve is installed. Common valve is used to provide pressurised air as an input to the "Pressure gauge" to measure the pressure.

Leaking around Pressure Switch. Ordered & replaced switch but still leaking


Some pressure switches have a valve that reliefs the compressor head pressure when the motor stops and closes the head pressure relief valve when the motor runs.
There is a check valve that keeps air pressure from coming back to the compressor head and the relief valve.
I think the check valve is leaking tank pressure to the relief valve and compressor head.
The check valve is where the pressure switch mounts on to and it mounts threaded on to the compressor tank.
Try replacing the check valve

If pressure on display is higher than set pressure of your safety valve,then your safety valve is doing its job. If pressure on display is lower than set pressure of your safety valve,then your safety valve is defective.

IR330E20 Air Compressor check valve leaks


The in tank check valve could be leaking since the pressure switch vents head pressure. If the check valve doesn't close, air will continue to vent from the pressure switch.

We have a craftsman 60 gallon air compressor model 919.175.260. The valve on the side of the pressure switch is leaking air. What might be wrong? Thanks.


If their is air leaking out of the pressure switch after the motor turns off you have a stuck or broken tank check valve. The check valve (PN CAC-437-2) is located on the tank where the line from the pump goes into the tank. There is also a smaller line from the check valve to the pressure switch. If working properly, the check valve lets air into the tank but closes when the motor shuts off. The pressure switch then opens a valve to the smaller line and lets the pressure out of the pump head and lines so the motor can restart when the pressure drops. On rare occasions you can remove the valve and clean it, but more often than not, you have to replace it.

DTC P0128: Engine Coolant Temperature (ECT) Below Thermostat Regulations Temperature

DTC P0411 : Secondary Air Injection (AIR) System Incorrect Air Flow Detected

DTC P2440 : Secondary Air Injection (AIR) Valve Stuck Open

DTC P2431 : Secondary Air Injection (AIR) System Pressure Sensor Performance
Circuit/System Description
The secondary air injection (AIR) system aids in the reduction of hydrocarbon emissions during a cold start. The system forces fresh filtered air into the exhaust stream in order to accelerate the catalyst operation. An electric air pump, the secondary AIR injection pump, provides filtered air on demand to the AIR control solenoid valve/pressure sensor assembly. The AIR control solenoid valve/pressure sensor assembly controls the flow of air from the AIR pump to the exhaust manifold. The AIR solenoid valve relay supplies the current needed to operate the AIR solenoid valve/pressure sensor assembly. A pressure sensor is used to monitor the air flow from the AIR pump. The powertrain control module (PCM) supplies the internal pressure sensor with a 5-volt reference, an electrical ground, and a signal circuit.
The AIR diagnostic uses 3 phases to test the AIR system:
DTCs P0411 and P2430 run during Phase 1
DTCs P2430 and P2440 run during Phase 2
DTC P2444 runs during Phase 3
During phase 1, both the AIR pump and the solenoid valve are activated. Normal secondary air function occurs. Expected system pressure is 8-10 kPa above BARO.
During phase 2, only the AIR pump is activated. The solenoid valve is closed. Pressure sensor performance and solenoid valve deactivation are tested. Expected system pressure is 15-20 kPa above BARO.
During phase 3, neither the AIR pump nor the solenoid valve is activated. AIR pump deactivation is tested. Expected system pressure equals BARO.
In all 3 phases, testing is accomplished by comparing the measured pressure against the expected pressure. The PCM can detect faults in the AIR pump, AIR solenoid valve/pressure sensor assembly, and the exhaust check valve. The pressure sensor can also detect leaks and restrictions in the secondary AIR system plumbing.

Motor "bogs down" at roughly 120 psi...almost stops


You suspect this unit as being a two stage because of the unusually high cut off pressure. It is a single stage and the motor really has a difficult task and is being pushed to the limits. to reach this pressure. We usually reset the pressure to lower setting ~~ say around 140. Your pump probably has a leaking intank check valve (brass fitting at tank) or leaking valve plate in pump. Simple tests : with pressure in tank unplug compressor from outlet and listens for air leak around pressure switch. As you unplug the running compressor from outlet you should hear air leaking from pressure switch for just a moment as air is let out of airline from pump to tank. If air leaks out till zero pressure then change the valve. If tank holds pressure then valve probably ok. Next test, with no air in tank and air filter removed, plug in compressor and feel intake port for strong suction. If the valve plate is bad, suction will decrease as pressure neers the 120 mark till the point of feeling that air is actually blowing out of intake. With good valve plate there will be strong suction untill unit reaches set pressure. If valve plate is bad also change the cylinder and piston ring. Good luck with your repair.

Why does my compreeor switch release the air after reaching the required pressure instead of holding the air at the required pressure??? I've just purchased and fitted a new automatic cut off switch to my...


There are two valves in play here. There is a relief valve that opens when the motor kicks off to release the pressure in the compressor itself. That is normal, and is required so that the motor can restart next time without having to overcome that pressure. The other valve is the problem. It is a reed valve between the compressor and the tank. This valve's job is to prevent the air in the tank from returning to the compressor. Think of it as a ratchet for the air. It is this reed valve that has failed.

Ingersoll Rand Air compressor loosing pressure


sounds like you have a problem with the discharge valve on the secondary cylinder, some I.R. pumps rely on the cylinder head valves to hold back tank pressure when the pump comes to a stop. the line down to the crankcase in front of the crank is a unloader valve that dumps the air pressure inside the pump to allow the next restart. I think that once you drain the tank and remove that cylinder head you will find a defective valve in the head.
