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.

- Q:I don't have one single water shutoff valve in my house that will shut anything off completely. It looks fairly easy to repack them, and I have the tools, and there are instructions all over the internet. The question I have for the experienced among you is what packing material do I use? I have heard graphite thread and teflon tape and even joint compound.Is one better than the other? Easier to use?Also, if there are any pitfalls I should know about before I undertake this, please advise.Thanks in advance!
- For stopping leeks use teflon tape to lub your valves use plumbers grease it s good idea to have a tube around not expencive
- Q:I need to make a ball valve that will open with no manual force but by a motor of some sort to spin it and release water. how do i make a ball valve controlled by preferably a motor or other CHEAP device. I need to do this for less that 20$
- It's a lot easier and cheaper to buy the valve at a hardware store than make it. You can probably get a motor and gear train from a hobby store. If it doesn't absolutely have to be a ball valve, you can get electric sprinkler valves from just about any home and garden supply. They're specifically designed to control water flow. Just hook it up to a power source and you're good to go. Addition: Just remembered, you can also get battery operated water control valves that connect between a faucet and a hose. I'm pretty sure they're ball valves internally. Prices vary, so shop around. Depending on how fancy you want it to be, they go for about $5.00 and up.
- Q:Can someone please explain the difference between a pressure tap valve and a gate valve (if any).
- they have different functions, the pressure bypass valve is normally used in Heating systems, between the Flow and Return circuits, just in case all the radiators are shut and the water has no were to flow, some of the more sophisticated use a pressure differential between one side of the circuit to the other to operate, Also generally set at quite a low pressure. Pressure release valves are used on closed loop central heating systems or other water systems were unwanted pressure can build up, and usually will vent to some sort of outflow, IE over flow pipe or return to a hot water tank and operate at higher pressure and are more likely to be adjustable
- Q:i am wanting to know if there is a diagram of the engine or at least if you have to remove the intake manifold to get to the egr valve.
- there was an extended warranty on the EGR valve to 8 years or 80,000 miles from new for problems related to insufficient lift of the valve because the port that the exhaust gas flows through gets plugged with carbon. if your car is within the 8/80 take teh car to a honda dealer for a free replacement of the valve and tube if you need to do it yourself or have someone else do it I can scan a bulletin if you want the details of how to do it. if you want that, send me an email by clicking on the icon above my name to the left of this answer and select email be sure to include your real email address that I can send an attached file to because Yahoo Answers doesn't allow attachments. Doing it this way keeps your email address and mine out of the searchable Yahoo Answers database hope that helps
- Q:I somehow lost the valve cap to one of my tires. Do stores sell replacement caps? If so, would a place like Sears or VIP be a good place to look? If not, would a bike tire valve cap work?In the mean time, i took a cap off the fullest tire to put on this one(the lowest) was that good or bad idea?

- Q:I've found a little beemer that's only $800. I would like to have it as a 2nd car that I'll use in case something's wrong with my main car to loan maybe once or twice weekly to my neices (16 yr. old twins). The seller says it needs a valve job. My question is, will the valve job cost me more than the car?
- You bet it will! A valve job may uncover valve guides that are out of specification. In which case the old guide hole will have to be drilled out and the guide hole honed, new bronze / nickel or hardened steel guides pressed back in. An ordinary valve job is relatively straight forward and easy but the labor involved with the tear down a new head and valve cover gasket without valve guide repair will run nearly $1,000 at a BMW dealership and 20 -30% less at a private mechanics shop. Most private mechanics AND dealerships do not do the actual valve job. The cylinder head with the valves are sent out to an automotive engine machine shop where the actual work is done. The dealer or private mechanic does the disassembly and reassembly of the head back on the block and gets the car running again.
- Q:I have a mountain bike that my brothers left me. the tire in the front is a normal s valve, the one in the back is a presta valve. now this was ok because it was fully pumped up, but then it popped on the road, so i got a new tire ad put it on and was all ready to pump it up but when i tried to pump it no air would go in. so i looked at it a while and i figured out the top unscrews, so i unscrewed it and put the pump back on and started pumping, but after a while i figured out that no air was going in the tire and now i'm very confused.

- Q:In December I got a new John Packers Bb Cornet and it was fine to start with. But recently the valves have been sticking, especially the 1st and 2nd ones. Even when I put valve oil on them they stick. It's really starting to annoy me, is there any else I can do to prevent this?
- If the valves continue to stick after being oiled, then it's time to clean your horn. Remove all the valves (making sure to keep them in order so you don't put them back in the wrong casings) as well as the slides. Fill a sink with warm (not hot) water with liquid dish soap. Wash all the parts gently with a soft clean cloth. There are special brushes available at music stores for cleaning the insides of slides. After cleaning, pat everything dry, apply fresh grease and oil, and reassemble.
- Q:Could my subs kill my EGR valve? I replaced my O2 sensor and my check engine light didn't go off. So I had it checked again and the same problem was still there. It said that all the cylinders were running either rich or lean..... I can't remember. But I was told it could be the EGR Valve so I replaced it and for about a week the check engine light was off.Now its back on. Had it checked again and the same deal was going on. Oh there was also a low voltage reading..... which is why I'm thinking its my subs.So could it be my subs that keeps killing my EGR valve? And any solutions will be helpful. I don't want to have to replace my alternator because its in an extremely tough place to reach. And I already have a small Cap.... .5. My subs handle 600 RMS total. WOuld getting a bigger Cap help?
- next time state year/make/model/mileage. most egr valves operate via vacuum. your subs can't affect a vacuum operated egr valve. if the o2 sensor didn't help out, you probably have a bad vacuum hose somewhere. that will cause the system to go into havoc because the car computer can't compensate for the excessive air being sucked in. a cap does not help with anything except for a loud THUMP. the THUMP causes a voltage spike and stresses the charging system. the cap takes care of the thump safer, it's not a complete solution.
- Q:I have a 98 Mitsubishi Mirage, seems there is a valve cover oil leak, i know this can be easily fixed by replacing the gasket.. but how will i know if the leak isn't from the valve cover gasket . Is the cylinder head gasket a major issue also .. if its not really the valve cover thats producing the oil leak should i not worry and just replace the valve cover gasket .?
- Sounds like you should clean your engine, then take a look to see where the leak is. Have you tried tightening the valve cover bolts?.
