FAQ of Cast Steel Check Valve:
Q1:I can’t find the type of steel check valve which I need. what can I do?
The chart above only lists out some common composition of steel check valve parts.We may provide other different parts material composition according to the customer's request or the actual valve working condition.
Q2:Which certification do your products pass?
Our products are in accordance with ISO 9001、ISO 14001、API 6A、API 6D、TS CE、API607/6FA/BS6755.
- Q: I need the valves that I need to press down for the notes on the bass stave. Can someone please write them down for me in a list like this?F = openG = 1 and 3A = 1 and 2 etc.Thanks people.
- I'm sorry I don't play the tuba and so I don't know, but please don't refer to a tuba player as a tubarist! I mean, I got a good laugh, but that isn't a word. They're called, tubists.
- Q: any flash files explaining valve operation maintenance will be very much helpful
- Pressure okorder /
- Q: okay i have a 1990 plymouth laser. it runs very and the compression is good but it smokes. im thinking valve seals? Also i need to know the tool to remove the seals. Thanx
- spring compressor is only special tool you need, can borrow one at autozone for free (you pay a deposit but get it back) but one question, does it smoke when you start it up then quit after a while? that is valve seals. If it smokes after warm up and when you accellerate its probably the wiper rings in the engine.
- Q: My valve covers are leaking how do I take the intake off my v6 firebird?
- You probably don't need to. Just tighten the screws up a little bit. several years, GM decided to use gorilla snot (silicone) instead of real gasket material. THis was a BIG mistake. I don't know if this is what you have. If this is so, Fel-Pro makes wonderful REAL gaskets. IF you need more info, check with local libraries for the ALLDATA data base. It shows you everything in great detail. Sometimes, oil gets forced through covers due to a clog in the oil pressure relief valve, which is part of your oil pump. You should do a chemicla engine de-sludge to clean this thing out as a preventative to futire woes. THen switch to a good synthetic oil, like Mobil One or Pennzoil Platinum. Your engine will just LOVE you for it!!!
- Q: In your explanation, be sure to:- identify the function of a valve in relation to the flow of blood- identify two places in the circulatory system where valves are found - identify one specific valve by name and describe its specific function
- Function Of Valves
- Q: Why would oil be leaking from a blow off valve?i own a 05' gti 1.8t, i have had the blow off valve for about a year now, its a HKS SSQV, but i just revently noticed that when it blows off, there is a spray of oil that comes out..... why would it be leaking oil through the blow off valve? i know VW dont really go well with blow off valves, but it hasnt given me any problems until recently....
- vw has a pcv system it recirculates the crankcase air into the intake, your car if fairly new, but this is most likely the problem. at least its the most simple to check / fix. i dought the turbo is gone if its the stock ko3s, they can take a beating. the pcv valve is the black saucer shaped peice (kinda looks like the stock diverter valve) , its in the TIP by your N75 valve. these get filled with oil and start to dump in into the intake. did you switch the set up to run the BOV on the cold side? like off the throtal body hose? if so, this could STILL be the problem. if you take off your lower inercooler pipe and look inside for oil build up. and pull the n75 valve out and check it for oil. id think aboout replacing the pcv valve with a catch can. your real problem is yet to be noticed if your dumping the air out and not recirculating it into the intake, the car WILL RUN RICH, as it reads the air it adds fuel, but with a BOV your loosing some air BUT keeping the fuel. so id expect to see some bad cats and o2 sensors good luck
- Q: In place of actual valve oil, can I use WD40? How about baby oil? Are there any household products which work?
- A bottle of valve oil only costs $3-4, so next time you go to the music store, buy two bottles. Then you'll be set for a long time.
- Q: i have been told that a bad EGR valve (exhaust gas recirculation valve) could cause a car to buck or hesitate in mid range speed at low rpms, thats what my car is doing. i work at autozone and i used our code reader and there was a code that stated EGR flow malfunction anyone else have this problem ever? please help me! i dont wanna spend the $120 if i dont need to!
- to attempt the EGR valve operation, start up the engine and then disconnect the administration hose The EGR valve could open and engine could sluggish or hesitate. If disconnecting the hose makes no difference, the two the hose is leaky/ blocked or the EGR exhaust gas pipes are blocked. in case you intend on changing it your self spray it with wd 40 or a sturdy penitrating oil and enable it soak. and while reassembling it use an anti grab compound on the threads
- Q: I have a WRX. slightly modified. im getting some upgrades here soon. clutch, brakes, and catback exhaust. i have a blow off valve i bought a while back, but found out it was illegal here in cali. if you know about blow off valves, then respond. is it worth putting on? what are the consciences of having one illegally if noticed by cops? all i know is that it sounds bad ***! :)
- I drive an STI and i would highly recommend not putting a blow off valve on your car. You won't get pulled over for you BOV but unless you remove all of the cat converters (very illegal) you will lean burn and tear up you cats and send debris into your turbo and mess that up. It is safe to run a recirculating blow off valve because you don't throw off the fuel air mixture. It isn't as loud but you won't have the hesitation and lean conditions that ruin your car. If you are going to install all of those after market parts you should think about more fuel delivery and a decent engine management system or you will inevitably run lean (its a subaru thing). If you want an open atmosphere unit and your car to still run right AEM EMS is a good option because you can change for your MAF car to a MAP one so open venting is fine. Also Perrin has a blow through tube you can use with there Rotated mount turbo kits (very expensive 4000+ with tuning). I use the Perrin system and its great but a lot of work and it requires a front mount to use an open air blow off valve. Hope all this helps, feel free to email me with any more questions.
- Q: anyone know .. if the 5.7L Hemi 2003 has a egr valve?
- egr valve is easy to locate, some are electric and some are mechanical, but anyways its somewhere on the intake with a metal tube coming from the manifold to it. hard to explain, and has like to vacuum lines hooked to it.
