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: What is it for? I was given a data set which is a result of antisurge valves testing every 2 seconds or so. (more than 1000 rows, measurements by time) I have no idea how to start analysis of the data like that. Can anyone help?: I would think your spreadsheet is charting every move that the anti-surge valve makes - for example if it opens slightly, it takes a reading, if it closes, then another reading etc. Like the other guy says, it's there to basically protect the machine from surging, and no-flow. You should be able to decipher specific actions from those readings - Recycle Trip or Safety On for example. Recycle Trip is when the software sees the machine approaching the surge line and opens 10% (for example 10%), so you should be able to analyse whether you've had any of these events. As far as I know that's the only reason you would study that data - to compare the action of the anti-surge valve, with the process conditions at the time.

Q: My chevy s-10 pickup automatic is shifting rough from 1st to 2nd, gives the truck a bump when shifts. Tech says I likely need a valve body replacement. He also indicated I could drive this for a while if I wanted. What more can happen if I prolong replacement? Truck is still at a fair blue book value and I'm wondering if I should sell it now. I have been very lucky in not having to sink any $ aside from normal wear and tear into it, so for me to have it replaced is the first $ investment. I have 103k miles for 2000. Anyone else in a sim sitch, or having multiple problems at this mileage as well? I'm wondering if this is the begininng of the end?: one thing i have done on some cars with shifting problems is to flush the trans fluid. bring it to a good shop and have them FLUSH it , not just change it. you can do it yourself without any special equipment but you will have to drain and refill the system about 3 to 4 times driving it a few miles inbetween to circulate the oil - it is a real pain in the ***

Q: Is it supposed to go on or only in cases when the power goes out??? I bought this pump and the directions are horrible!!! There isn't room for both the air stone and the check valve!! How does this stupid thing work???: Keep okorder /

Q: What does the egr valve do?and what does it do to a car if you have a bad egr valve?...what about performance wise?: can an egr valve cause a car to stall or misfire?

Q: I would like to know about the signal pneumatic valves are drivesn (PWM,PCM?) and about their bandwidth and bit rate. Where can i find info?Thanx!!: first of all, lemme be frank to say that your question is not clear to me. however, i wud like to give my answer below with my understanding of your question. generally, the term pneumatic valve means that the actuating force to operate the valve itself is pneumatic(driven by air pressure) and not the service fluid (i.e. the fluid which passes through the valve). with the above understanding, industrial standard pneumatic pressure could be 3 - 15 psi (or) 0.2 to 1 kg/cm2. on the other hand, if your question means that you want to know about the electrical driven valves, then the industrial standard is 115VAC Solenoid valves (or) 24VDC Solenoid Valves. There could be other ratings as well.

Q: if i put a power valve on my honda xlr 125 would it make my bike have faster acceleration: The powerband is caused by tuning an engine, they are most noticeable on a small lightweight 2-stroke. When you are riding and you change up too early you will have noticed the bike slows down and does not accelerate very well, but if you keep the rpms within a certain range it will accelerate smoothly – that is the effect of a powerband, it can be moved up or down the rev range by altering the ports and by changing the harmonics of the expansion chamber (the trumpet shape of the exhaust system). Either your garage is having a laugh at you or they are hopeless – I suspect the former. EDIT: You make it faster by tuning it –?making it less reliable and these bikes are already peaky. If you make them more peaky you will need to run them at higher revs –?higher revs = more power from available torque, therefore you do not want to move the powerband down the range or broaden it. Changing the sprockets will not improve acceleration AND top speed it is one or the other.

Q: i was told my egr valve needs to be replaced, so im wondering if the system cleaner will help at all. thanx: Not really. The EGR valves on newer cars have an electric solenoid that moves the plunger up and down via advice from the computer or engine management system. Probably 90% of the time the valve has a piece of carbon stuck in in that broke off iinside the intake manifold and or gas passages in the intake manifold leading to the EGR valve. They can remove the EGR valve and clean it out and reinstall it. A bad EGR valve will either have a bad solenoid coil, or the valve plunger is burned from the hot exhaust (from age and high mileage) gases not giving an air tight seal when it should be closed at idle. A fuel system cleaner is a good idea every 3K miles especially if you buy the really cheap gasoline that has a lot of alcohol in it. The alcohol creates more soot than pure gasoline or gasoline that has detergent added and this soot leads to the little carbon pieces that grow and collect in the intake manifold and on the injectors. Good Luck!

Q: I got a cold air intake installed on my vehicle and don't have any AEM bypass valve installed, for preventing hydrolock. If I drill a small hole(e.g 1cm) on the intake(short ram section) can that prevent hydrolock or do I still have to get one of those bypass valves?I'm looking for any alternatives, instead of those AEM bypass valves and was wondering if drilling a small hole in the cold air intake could help in preventing hydrolock, just as good as the AEM bypass valve.: By far the safest and most sensible way is to stick with the cold air intake that came with the car. You can't buy a better one for less than $1000 anyway. The stock intake has preheat to warm up the engine more quickly, improving fuel economy, and has been tested with the actual car model to minimize the risk of sucking up water. That is not a foolish worry, either. Our New Guy at work had a Scion with a KN intake that he tried to drive through water that was deeper than he thought. The engine did not survive it.

Q: My brother is 32 years old.He has an enlarged heart ,a murmur,high blood pressure and heart regurgitation.He may be having the valve replacement surgery.I was wondering if anyone has had these things wrong with them and had the valve surgery and did well afterwards.Any information would be very much appreciated.: Guy I work with just had 2 valves replaced. He honestly didn't know anything was a matter until he collapsed at work. They ran some tests and figured out that was his problem. Talked to him a few days after his surgery and he said he hasn't felt this good in a long time. Its a common procedure nowadays, and your brother should most definitely be in good hands. Keep us informed, and best of luck to you both!

Q: Where do I get a electric valve with a 120 VAC coil: Cheapest okorder /... Grainger being a major supplier of parts - note the high cost of many of these because of being high temp steam and hot water under pressure and look for other choices.
