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'm thinking of buying a used 2006 Volkswagen Jetta. It has a 1.5 liter 20 valve engine, and I really don't know what that means. That's good, right?And is this a good used car to buy?
- Are you sure its a 1.5 liter 20 valve engine? Jetta's of that year came with a 2.5 liter 5 cylinder engine (which would have 20 valves, 4 valves per cylinder.) Basically what valves do is some open to allow air to enter the cylinder, and then some open to allow the combusted mixture of air/fuel to exit. Most vehicles (to my knowledge) have four valves per cylinder nowadays, I know it was less in the past, but I think just about all have four valves per cylinder now. Five cylinders is just one more than four, one less than six. Oh, and Jetta's are actually quite nice vehicles. I would definitely pick one up if I were in the market for a used car, and found one at a decent price.
- Q:I have a 97 Neon. The Canister Purge Valve circuit gives a code 31 stating that it has a problem. I've replaced the valve, which didn't make the code go away. I removed the battery for a few hours, and the code went away. I drove for about 2 weeks and the code came back on. If it's not the valve, where do I look next?
- Could you describe this canister purge valve? Not sure what you are talking about here. Is it part of the emissions, part of the radiator, or what. I am just guessing it's part of the emissions. In which case, I need to know if it has a smog pump. Could be the pump, could be a clogged up cat, could be a bad EGR valve. Need some more info to help beyond this point. Good luck.
- Q:I have a shut off valve under the sink that leaks when you try to turn it OFF. Why is that?I need to fix faucet leak as well. do i need to shut water off to fix faucet? Need to fix valve first. Cant figure out why valve leaks when turning off.
- Because the stem washer is worn out and needs replacing, you will have to shut off the water to the whole house and you might as well replace the shutoff, probably just about as cheap and a lot more reliable fix.
- Q:When i went to the cardiologist a few months ago, i remember him saying that my pulmonary and tricuspid valve were leaky, and i think he said they were a 1 on a scale of 1 to 4 which is minor and of no concern. but i have valve problems in my family and i got thining about it. anybody know what this scale is called/have more info or was it something he just made up to tell me that it was minor?
- With a tape measure.
- Q:I heard alot about blow off valves making your engine run rich, but I want to get a blow off valve or bypass valve when I get a wrx. (I know some people think they're gay) but i dont care how loud it is, just want that sound. so what's the difference? I've been looking at this one:
- They guy above has some of it. The reason it runs rich is because when the stock by pass valve releases the air back into the intake, it does this after the MAF sensor. Since it is getting a big surge of extra air that the MAF does not read, the ECU automatically increases fuel for a split second when the BPV releases. When you suddenly release all that air into the atmosphere, the computer does not know it and still ups the fuel. That seems like not a big deal but it runs really hot and can do things like foul up plugs and even melt the catalytic converter. There is also the issue with most aftermarket units causing stalling when you first step on the gas or even when sitting still. If you want a little noise, I would first look to getting rid of the intake silencer in the fender. It looks like a milk jug. If that's not enough, then look into an open ended intake. Just be careful with intakes as they also can cause issues depending on the brand and they rear of the car. At least an intake ca be tuned for though. The issues with a BOV can be reduced a little with tuning but can not be eliminated. Sow know that you know the risks and how it does absolutely zero to benefit the car, spend the money on something better.
- Q:does anyone know how much work it would take for a 1998 Mazda 626 (2.0L MFI DOHC) to change a bad intake valve?what work would be necessary and what kind of price are we talkin?
- What diagnosis gave you the fact that you need a cvalve changed...dis you not replace the timing belt and it bent the valves(major head repair) or did you do a compression check to determine you have bent valve (intake valves don't burn) (lesser repair)
- Q:i have a nos tank that my grandfather gave me and i was wondering if i could get a scuba valve and put it on there so i can fill my paintball tank up with the air so i dont have to go buy a scuba tank
- srry but if u do that it works very poorly so i would buy that scuba tank
- Q:My friend is having 3 valves in her heart replaced with pig valves. Her dr said that putting in human valves raises the risk of her body rejecting them but wouldnt your body also reject a part form different species? And if they only last a few years why use them at all? shes all freaked out about the surgery so I dont want to ask her too many questions

- Q:A question about a hot water radiator bleed valve. I read the advise on previous questions and bleed all my radiators except one where the bleed valve broke off when I tried to turn it with the key. My question is that on the other side of the radiator near the floor there is a black knob that turns which I assume should shut off the radiator. If my assumption is correct then I should be able to shut this off and then remove the bleeding valve and replace it without bleeding the system.. Does this sound right? Thanks,.JOE B
- It has been a long time since I have seen a system like that, but I believe you are correct. The knob on the opposite side of the bleed, is a flow control, which is used to adjust the amount of heat from the radiator. If you turn this all the way off, it should stop the water flow, providing it is not corroded. However, be careful when removing the bleed as the radiator will still have water in it. Try not to drown the neighbours.
- Q:I just installed three anti-siphon valves(jar top,orbit) for a sprinkler system the main water line is 3/4 then goes into my manifold (pvc)3/4 schedule 40,usually when you turn on the water it comes to a stop where you re valves begin then you either open them manually or their set up through you re timer, the problem im having when i open the main water line the water goes straight through the valves without me even opening them my question is can it be to much pressure or what can the problem be? any info helps thank you
- There's a small button on top of the elec valve, which is a manual override. Find it, and be sure it's turned all the way to the right, like tightening the cap on a bottle. This closes the override but doesn't affect the solenoid operation. If this isn't the problem, disconnect the control box from power, and see if the valves now are closed. Might be wired wrong, and the solenoids are stuck open because of always being powered. Too much pressure isn't the problem -- when a home is built in a place with abnormally high water pressure, pressure reducers are installed to diminish the pressure to workable levels.
