does anybody know how to do valve maintenance

i got some blitzluft 280 p.s.i valves and my trucks coming all back apart so i can weld some support bars and some other shit to it but i was wondering if any body out there wanted to tell me how to clean my valves! i don't want to take it apart and fuck something up,just some routine maintenance

Taking them apart won't hurt them at all...You're going to want to check the springs for wear and soak the diaphram in warm soapy water. If there was any rust in your tank, it surely got into your valves. It is a good idea to run a water trap also if you don't have one already. If you have any problems, get ahold of me monday morning. 877-324-6464

I got this off another forum its for smc valves but im shure a lot holds true to your valves.

Have you had a problem with your valve sticking? Or leaking air in or out of your system?Well here is a step by step walk through on how to clean out your valves and make them work good as new.1You are going to need a few tools for this (1)15/16

Now press down on the coil and remove the clip the rest of the way with your fingernail it will pop free.You will now be left with what is shown above. Place all above pieces in a safe place.Now is a good time if your coil is in bad shape does not work correctly or has the wires cut to short you can buy a replacement coil from suisidedoors.comhttp://www.suicidedoors.com/SMCValveCoil(solenoid).php15Now grab your 15/16” Deep well or sparkplug socket and slide it down and lock it securely over the post section of the valve. NOTE: This part is very tight I HIGHLY recommend removing your valve from your setup and place it into a vise wrapped in a towel as to protect it and to allow you to get better leverage for removal.When done you will be left with what is pictured above.Now The plunger may fall out of the valve when you remove the stud section. This is Normal. NOTE: be sure not to loose the small spring that is located inside of it! The spring is tapered so make sure you replace it in the correct orientation.Now you will want to strip off all the old grease from this with your isopropyl alcohol. When dry grab your lithium grease and light lubricate the surface and work it in with your fingers. NOTE: you do not want too much as to be Visible , Just enough to lubricate.Now also do the same with the INSIDE of the valve post we removed earlier. Poor a small amount of isopropyl alcohol inside plug with your finger and shake it up. Then poor out remainder let dray and spray a quick burst of Lithium grease or put a small dollop of grease on the inside edge.16Inspect the rubber matting surface IT should have a slight dimple in the rubber. If it is cut deep or dirty this will lead to the valve sticking as well. Be sure to clean this surface with your isopropyl alcohol.17Re-assemble these parts and spin the plunger and move it up and down with your thumb to make sure it moves freely and to help spread the lubricant.Now inspect the Passageways on the pilot section for any obstructions. You can pour a little isopropyl alcohol into the passage and work it around. And blow out with compressed air. The center hole leads straight up. The left smaller hole Leeds into the main valve chamber.This is where it enters the valve body again make sure this is clean of any obstruction.NOTE: this small passage way is what tends to freeze up in the winter with water that gets into the valve.18Replace the ‘O’ ring back into the small cutaway on the main valve body. NOTE: this may be a snug fit.19Place the diaphragm assembly back on top of the ‘O’ ring. And square it up over the holes.20 Now place the upper valve body on top of the assembly. The spring will push up on the cover this is normal.Align up the upper cover and square it up over the holes and press it together and hold it together firmly and start threading in your screws by hand as to be careful not to cross thread. 21After all screws are snug you can remove pressure and fully tighten the screws. CAUTION: You will want to tighten the screws in the order listed in the picture. This will ensure a tight seal and prevent the upper body from warping or cracking.22Replace your ‘spring washer’ . NOTE: the washer has a bend to it, install the washer so if you look at it as a ‘C’ You will want the open side of the C to face the coil.23You can now install your coil and name plate. It should sit as pictured above.Press down on the coil so the spring clip gap is open.24Press in the spring clip as far as you can by hand and grab your standard screw driver.25Use the flat side of the screw driver to press the clip onto the stem..

You will now hear a

You should post that in the tech lib.

Good tech article. Haven't seen one that detailed. Anyone know that sell's replacement parts for the GC 250's? If so I will need a phone # if possible.

I do work at FBI, so give me a call monday and I'll take care of you.
