Good Morning, All, I am using some Parker IQAN PLC's for some equipment out in the field. IQAN uses an RJ45 ethernet port for diagnostics and software updates and I am wondering if any of you would have suggestions of products that I could use to securely connect to these machines remotely. I...

HI @FluidPowerUser, Apparently, my other valve had a slightly different configuration and therefore it could build higher pressures with the same pump compensator setting. That fooled me into believing that the pump setting wasn’t the problem. I can now correctly adjust and change pressure...

OK, back I come.☺️ I tried to install a KAS type compensator in my valve, all to no avail. A Parker engineer finally responded to my request and informed me that it should actually be just fine to have all standard LS compensators with an AS type inlet. I guess I am back to the drawing board...

That's also the conclusion I have come to, my mistake for not properly understanding the manual. I had understood it to say that the LS comps work just fine with the ASC and since that is the part our company had in stock for another application, that's what I used. As far as to which port my...

FluidPower, you did get me thinking, Do you think that I would be required to have at least one AS type compensator valve section? Thanks!

Absolutely! I apologize for not providing all the details immediately. Let me know if I miss any here. We are using an ASC mid-inlet which is designed for AS style compensators. We are not using any AS style compensators, but my understanding was is that it should work with standard...

Hi everybody, I thought I would give an update here, in case anyone has ever heard of a similar situation; for some reason adjusting the PLM relief screw does not even lower the LS pressure. Am I correct in my understanding that it should? Why would it continue to build pressure with the...

Thanks Compositepro! I will try that.

Would there be any way to tag the admins and ask them to do it? Let me knwo if you have ever done that before. Thanks!

Is it possible for me to move this thread? This is the first time I ever posted here.

Just to clarify, you will not insult my limited intelligence.😊 I am only an eigth grade school dropout trying to learn all I can by doing things. Hopefully I am not the one offending you with simple questions.😊 And no, I will keep on diagnosing, this is not the expected behaviour of this valve...

Hi FluidPowerUser, Not sure how familiar you are with these valves, but just in case this rings a bell with you, I seem to be able to build more pressure when using the LS port which is load signal that is copied, versus when I am taking it from the PL port which is uncopied load signal from...

As far as where I have tried for the pressure measurement, I have tried it on several sections, deadheaded, with the same results. I am using an ASC inlet here. And for the tee, all I meant was a test guage teed into the LS line running directly to the pump. I believe I will have to double...

I really believe that I can rule out the pump causing the issue because when I use another valve with different config I can easily build all the pressure I require. I am using electrohydraulic solenoid operation. You wouldn't suppose that some of Parkers solenoid options would in some wya limit...

No that doesn't really explain, because I have a section that is required to much higher pressure than the rest (300 bar) which I did not order with feed reducers because I assumed I would set that pressure with the PLM setting. The rest of the workports all need to be lower than 200 bar so I...

Ok, I got you now. I have always called them feed reducers. A section without any of these reliefs should reflect the value of PLM, correct?

As far as system pressure I measured directly on the work ports of the valves. Some of the workports have feed reducers installed and some do not. None of them have port reliefs. None whatsoever of the valves were capable of building more than 230 bar at the most. For the LS valve I placed a tee...

Thank you very much, @FluidPowerUser , Would you also know if PLS will limit the max system pressure? For more background, I am using an ASC type K220LS mid inlet. The only reason I used it was because that is what was available, it is not like I am using any AS type compensator spools. Now I...

Hi everybody, I have a couple of questions on a Parker K220LS valve using an ASC mid inlet. (part number 22000667) Would you know what the application uses would be for part number 9120092290? Can I use that in an ASC mid-inlet if I don’t have any AS compensators? Also, I would like to know...
