    Can the over pressure release valve be adjusted so that it blows off earlier?
    Remember anything you read on the internet was probably written by some guy sitting at home in his underpants! Including this !!

    So, as I understand it, the overpressure valve isn't there to stop the tank filling - that's the operator's job. The OPV is there to stop the tank blowing up if the operator isn't paying attention.

    The knob you identify is to "vent" the final stage if the safety valve malfunctions and you need to vent the filter system. It's not designed to adjust the safety valve pressure, indeed, I'm not sure it could, though there are individuals more knowledgable about this than I am.

    The slotted component in the second picture is the pressure maintaining valve - this adjusts the minimum pressure which the filter needs to reach before it will start to fill the cylinder, not the maximum pressure

    Which goes back to my first point - unless you have an automatic cutoff valve (and even if you do!) it is the operator's responsibility to ensure that tanks are not overfilled.

    Thankfully you have not succeeded in adjusting the safety relief valve (Yet) and for reasons I will
    explain I will not discuss how you adjust this.

    The safety relief valve is for your protection and should not be adjusted

    Provided your compressor is electrically driven what you need is known as a Pressure Switch.
    These are about £80 and are basically a self adjusting piston regulator attached to a electrical switch.
    You setĒ the cut out to your required 240 bar and each time the compressor reaches that mark the switch activates cutting power to the control relay in the stop start box.
    The relay then has no power and pulls out the magnetic starter contractor and the machine stops.

    This is your safety sequence for operation:

    1. The operator watches the filling rate and pressures and switches the machine off when full. Say 200 to 207 bar.

    2. The safety pressure switch will cut out power when itís maximum set pressure is reached or the operator fails to switch off. This setting should be set to your 225 bar

    3. In the event of either the operator or the safety pressure switch fails to perform the shut down the final stage discharge pressure relief valve then will lift,
    The compressor will continue to run but no additional pressure will charge into the cylinder. This would be set to 240 bar

    So two means of opperaton with two methods of shutdown and a safety device to cover you in the event of these two systems failing.
    Pretty much covers the operation procedure for running a compressor with pressure switch and safety relief valve. Iain

    final pressure safety valve

    ive got air leaking out of the fpsv and only have a primitive manual. my rig mechanic is no use. im baffled. can any light be shed on this. its a bit of a game changer for me. ive screwed it all the way in and out and still air comes out when the compressor runs, it should be going into a bit storage bottle..... but its not

    Is that the valve in the picture above you are taking about?

    Would be interesting to know how old the filter housing is and if it has been tested. Max life on them is 15 years.
