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 was adding air to my bike tires and the valve became loose. Do I need a new tire or is there a way to tight?
- A Schrader valve coming loose is a rare occurrence. If you didn't damage anything and the valve core itself is coming loose, there's a tool to tighten them. Old-fashioned valve caps actually had this tool built in. You can still buy the tools for a couple bucks at auto parts stores. But of course, a new tube will cost about $3 and solve the problem.
- Q: hey...im kinda confusedis cochlear an artificial valve???and if not..what is an artificial valve??
- Hello, i found this information online, hope it will be helpfull... ?Artificial valves can be used to replace damaged valves in the body that are no longer functioning to keep blood flowing in one direction only. ?Most artificial valves have a fabric ring surrounding them, which allows a surgeon to sew the device into place during implantation. ?Where appropriate, artificial valves are constructed from collagen-rich materials, such as pericardial tissues which have been obtained from pigs or cows and treated (to denature any animal proteins), to minimise the risk of rejection by the human body. Other materials used are cobalt-chromium alloys, low-temperature carbon and titanium alloy with pyrolytic carbon discs or balls.
- Q: large veins contain one way valves, which keep the blood flowing in one direction. why dont large arteries need similar valves?
- The heart actively pumps blood forward. That keeps it moving in one direction. On the other hand, venous flow is more passive.
- Q: I was just informed that my 4 year old daughter has been diagnosed with mild mitral valve regurgitation. I have been researching, but only find the information to apply to adults, not children.What general course is taken when dealing with children with this condition and what should I expect? Her pediatrician was treating her symtoms as asthma with breathing treatments, but, I was not comfortable and took her to my family physician, who sent her for the echo, which discovered this.I'm more or less just looking at our options...
- Find yourself, or your daughter, a good cardiologist and follow his advice. I do think that this can be handled with medications in kids as well as adults. Good luck.
- Q: Im putting in a new EGR Valve for my 94' Mazda MX-3 V6 1.8L and i was wondering if anyone had a guide or some special tips on what or what not to do...Thanks.
- One thing people don't do is bring the old EGR Valve with them to match it up with the new one before leaving the auto parts store. I would suggest doing this FIRST, if it is possible to get a ride to the parts store. I know you can't do this if the MX-3 is your only car lol. Be careful and take your time, do not rush and take digital pics before job is started so you know how or where things were durring re-assembly. And I do hope it is warm wherever you are doing this job,lol. Good question!
- Q: This valve has flow indication embossed on their body.
- Gate valves are used primarily for isolation, usually not for flow modulation. They are usually operated fully open or fully closed. Installing the valve with the arrow pointing in the direction of flow will have more to do with the tight sealing of the closed valve than with the operation when open. If the valve is to be installed in a pipeline where the flow is in either direction, pick the direction most important for good sealing. However, I do not recall seeing a flow arrow on a conventional gate valve.
- Q: Is there a difference between the atrioventricular valves in the right side versus the left side of the heart?Is there a different between the pulmonary valves?
- Right Atrioventricular Valve
- 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
- The valves in the body makes sure that the fluids flow in one direction, and prevent backflow. In the heart the valves prevent the backflow of blood to make sure it travels in one direction (atrium to ventricle). The valves are also present in the lymphatic system that makes the lymph travel in one direction.
- Q: I just bought my first bike in 20 years, and as a result have had to pump up a bike tire for the first time in 20 years. I was dazzled to discover a type of tire valve that I'd never known about. The Presta.So of course, I need a pump with a special adapter, I didn't know to unscrew that nut at first so I accomplished a whole lot of nothing for awhile, and once I did open the nut, the pump kept slipping off the tire once I got anywhere near the tire' recomended PSI until I awkwardly held it in place while operating my pump with one hand, which of course meant less leverage and so while I got above the min recommended PSI, I couldn't get anywhere near the upper end of the spectrum. Why would anyone use these ridiculous contraptions? The fact that they are used means there must be some rationale. A brief internet search seems to find more forum posts with people saying the alternative (Schraeder) valves are more reliable and don't leak as much either.Educate me!
- I've never had any problems with presta valves. I suppose their only advantage is that they can be fitted on ultra thin rims.
- Q: Ok i just be nt a valve on my 97 eclipse gst. I did a compression test and all my other cylinders were at 175psi which is good(thank god).My 3rd cylinder is only at 25psi.My mechanic will do the installation of the new valve but his friend has to do a valve job and re condition the whole head. Just because i guess your suppose to re condotion and clean the whiole head when this happens. What do u think a ball park estimate would be for this kind of work?I think he is going to replace all of the valves and seals y hes got the head off. The car has 100k on it and there is nothing else wrong with it. The guy i bought it from put a brand new bosch alternator and waterpump in and it also has a new timing belt so i dont have to worry about it skipping on me. WHAT DO YOU ALL THINK WHAT I SHOULD DO? HOW MUCH WILL IT BE? IS IT WORTH RECONDITIONING THE WHOLE HEAD? THX ALOT FOR YOUR INPUT.
- mechanic should have told you what the cost would be...and to fix it right you should do them all
