Products Description of Swing Check Valve
Check valves are used in pipes under pressures between PN1.6~16.0MPa(Class150~2500Lb), working temperatures-196~600℃, They are used in industries include oil, chemistry, pharmaceutical, fertilizer, and power gene-ration to prevent the backward flux of the media.
The main structure features of Swing Check Valve:
1、The products feature a reasonable structure, reliable seal, good performance and nice modeling.
2、Either soft or hard seal can be selected for the product upon different working conditions.The sealing face is built up with Co-based
carbide alloy, leaving a better wearability, corrosion and scrap resistance and a longer duration.
3、Small opening pressure, the disc can be opened fully with a very small pressure differential.
4、Inside-set bolt-bearing structure reduces leakage and reliable use.
5、PN≥16.0Mpa (class1500), the middle cavity uses a self-tightening sealing structure to have the sealing performance reinforced along
with the pressure rise so as to ensure the sealing performance.
6、Different parts materials and different sizes for flange, butt-welding are available for sensible combination according to different working facts and customers' requirements.

- Q: I was told Wed. that I need to have my aortic valve replaced. I was wondering if anyone could share their experience with this surgery good or bad. I am meeting with the surgeon on the 26th, and am very nervous. Any tips and or suggestions appreciated. I'm a 39 year old female.Thanks in advance
- Hello Lisa, Aortic valve replacement is a cardiac surgery procedure in which a patient's aortic valve is replaced with a different one. The procedure itself is rather simple. Your chest will be opened, you will be placed on bypass, valves exchanged, and closed again. The risk with respect to the procedure is generally cited as being between 1 and 5 percent. My advice to you is to call ahead, and specifically request to meet the physicians who will be performing surgery; including the Senior Surgeon, and Anaesthesiologist. In some cases, hospitals will provide a general doctor for questions; but it is important to meet all of those who will be operating, both for comfort and questions. When meeting with those who will be operating on you; ask them any questions you might have. They are there for you; to brief you on the procedure, ensure you are ready, and respond to any of your concerns. Dr. James Jeah MD
- Q: My friend had heart surgery and it was pretty serious. She got a new heart. Days later they checked her and discovered that she bursted a heart valve. The doctors say it's one she can live without. That really concerns me. The valves connect directly to the heart. Please help.. Will she be ok if she doesn't get it replaced?
- You can't live without a heart valve. Your friend might have a valve regurgitation which may not be a problem depending on the valve.
- Q: looking to get a greddy type rs blwout valve for my sti, but i wana noe wut exactly da blowut valve does....kause i just got da car and i bought warranty, and i wana make sure ma warranyt doesnt void.....and how hard would it be to change da blowout valves....frum ma old 1 to dis new 1......so just incase ma warranty does void kause of da blwout valve wenneva i have problems i could switch it back to da original 1HELPPP???
- Hey Dude, The other answers covered what a blow off valve dose very well... It simply releases boost pressure when you let off the gas. If you buy an atmospheric blow off valve you will cost power. All it will do is make a cool sound. The reason is that the computer expects the boost charge to be recirculated, not vented. The car comes stock with a great and fully functional recirculating blow off valve. Keep it, your money is better spent else where.
- Q: I have a 1997 ford aerostar and my mechanic just called me and said that the pop off valve needs to be replaced, but it is attached to the line so the hole line has to be replaced to. I want to try to find the pop off valve to see if I can get it b/c he can't find the replacement part, what I need to know is what it looks like. or where it is on an aerostar, because I have 5 more sitting in the driveway and I can look for it.
- 1. the pop off valve is normally located in the compressor so if it over pressures it will relieve some of the pressure. it's not in a line. #2. if it's a 1997 it doesn't have R12. it has R134. the only valve in the line is the port to check pressures and vacuum and recharge it. it could have one of those valves leaking and most can be taken apart and a new schrader valve installed. hope this helps.
- Q: My sump pump shut-off valve is very noisey. I wrapped insulation around it, but it still clunks. The clunk can keep me awake.
- If you mean the discharge check valve, it will clunk when the level switch trips the pump. The head or weight of the water trying to flow back into the crock causes the check valve to slam closed, making a clunking sound. This is pretty common and normal.
- Q: I've been working on cars since around march of 2012. I new. I have a set of 305 heads that were really dirty. It came from a 79 camaro that never had an Oil change. I took the valves out and the valves are pretty burnt. I was wondering If I cleaned them up would they still be good to use? The edges aren't rough or anything. Just let me know what is need to know please. The heads I know are still good.
- People reuse valves all the time, just need to inspect them for straightness, keep them in the same locations in the heads and relapping them is a great idea also.
- Q: I have an '03 vw jetta and don't know if I should get a greddy blow off valve or an injen cold air intake? Any suggestions? I don't know a lot about either, what is the difference between them?
- #1 blow off valve for a 1.8T is a bad idea(it will have to be a custom job since there is no place for you to mount it).....a diverter valve can be installed to replace the stock one, which vents the excess boost into the intake instead of the atmosphere. BOV or Diverter valve will not give you ANY noticable improvements at all on your stock car, they are used as protection on high boosted engines to prevent damaging the turbo(your vehicle's stock diverter valve does a great job at this when you're running stock boost levels). Buy the cold air intake and notice a difference in sound and performance.
- Q: im looking for the egr valve on a 97 mazda 626 its not in top of engine like other cars where can it be?????o and its a 4 cylinder
- You egr valve will be located on the exhaust or have a metal tube running from the exhaust the other side of it will be mounted on or near the intake. you can also look at the vacuum routing label on the hood if it is vaccum controlled it will be listed on the diagram
- Q: Im 17 with a Bicuspid Aortic valve and hypertension (around 160/85). Only other family member with teenage hypertension is grandfather. Im on 2 different types of hypertension medication which only brings blood pressure down to 138/75. It still jumps to 157/85 on medication. I have leakage of my valve that has not gotten worse or better since starting the medication (first checked in September, medication started in Novemberish, now April). No stenosis yet. Any idea what im looking forward to in next couple years? Or is this stuff spontaneous?
- Most patients with bicuspid aortic valve whose valve becomes dysfunctional will need careful follow-up and potentially valve replacement at some point in life. Regular EchoCG and MRI may be performed. BP reading (1) 160/85 mmHg. Stage 2 hypertension (Isolated systolic hypertension) (moderate). If the systolic blood pressure is elevated (140) with a normal (90) diastolic blood pressure (DBP), it is called isolated systolic hypertension. Pulse pressure is 160--85 = 75 mmHg. Optimum pulse pressure is 40 mmHg. A higher pulse pressure may mean your heart's valves are leaky (valve regurgitation). BP reading (2) 138/75 mmHg. (Prehypertension) Pulse pressure is 138--75 = 63 mmHg. Pulse pressure 40 mmHg is abnormal. BP reading (3) 157/85 (Stage 1 hypertension) (mild) Pulse pressure is 157--85 = 72 mmHg. Cardiovascular mortality risk doubles for every 20 mmHg of systolic BP or 10 mmHg of diastolic BP over and above the normal blood pressure of 120/80 mmHg.
- Q: like my Acura has a 16v 4clyinder engine , and i dont know what valves does , the more vavles the faster?
- Valves are in the Cylinder Head, They let Air and Fuel into the combustion chamber. 4 vavles let more air and fuel in than 2 vavles, Which makes more power.
