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 am having a leaky valve is that normal? the doctor said that it is normal what do i do?
- If its not serious, you should have a normal heart rate. My heart rate has always been normal, and i have Aortic Regurgitation (leaky valve), Aortic Stenosis, Bicuspid Aortic valve, and a slightly Enlarged Aorta and my Cardiologist For the last 15 years, has said i have a normal heart rate. So your heart rate should be normal.
- Q:I have to get a new vacuum switching valve for my 1987 toyota pickup. I was just wondering what it does, and if a broken one would cause my truck to not idle. It still runs fine when i drive it, but when i push the clutch in the RPM's get really low until it dies.
- Vacuum Switching Valve
- Q:Can someone explain to me what lead and lag time are? Also, what are the three flow characteristics? Linear, equal percentage but what is the third. If I wanted to have a minimum stop at 25% on a non-linear valve such as a butterfly valve, how would I achieve this. Obviously you cannot just restrict the valve by 25% of its travel as it is not linear
- Hope this helps in some way... To start the 3 main flow characteristics of a control valve are Liner, Equal percentage and Quick opening (or fast opening). If you interested there are also other characteristics. As far as i am aware the lead time is the time in which a signal is sent to the valve and the lag time is the time in which the actuator moves and closes the valve. The pysical movement. As for your final question the only thing i can think of is to alter the actual size of the butterfly valve or put a reducer before it. Sorry if my information was of little use.
- Q:the water coming out of the kitchen faucet has been getting weaker and weaker this week and now it flows a 3 out of 10. The thought it might be time to replace the faucet/faucet washer. I went to turn off the water under the sink.. hot and cold valve but water still comes out of the faucet with enough force aka not a dip but free flowing water. I turned the red handle valve to off as well but same thing. I am totally thrown off. HOt and cold water still comes out of faucet. When I push the faucet handle down, the water does not stop right away as well but slowly stops. No problem water into dish washer. I have replaced numerous faucets but I can not figure how water is still getting to the faucet after turning all 3 valves to shut off position. I still think it might be the faucet but now I am not sure. I am close to calling a plumber but really do not want to do that. thx
- shut off you water main first so you can check on your kitchens isolation valves. unscrew your valve try to replace the wornout rubber gasket. unscrew your faucet and clean the faucet with brush and clean the strainer of your faucet. change the gasket or ceramic valve of your fauset replace them. i hope this will solve your problem.
- Q:So it always seems that when I see the jet and foot valve out of a well there's a drop tube between the jet and foot valve. My question concerns this drop tube- is it necessary? I've got a leak somewhere, replaced the foot valve and still have a leak. I'm inclined to get rid of the old drop tube, it's crusty and likely to be the source of leaks either now or in the future. any reason to not just plumb the foot valve directly to the jet? Thank you kindly for useful information.
- This drop tube is the suction line. This tube will always be below the water level in the well. I would talk to a competent water well company and get their recommendations. Regards, Dale
- Q:Why are pig hearts valves used as replacements for damaged heart valves in humans? Are there any complications and are they still used today?
- They are called porcine valves... they are used very frequently because you don't have to be put on anticoagulation. But, the down side is... they only last about 15 yrs and then they have to be replaced. A pigs heart is pretty close to a human one.
- Q:im 16 and im rly scared i have already been checked out by the hospital and they sed that i have a moderately leaky heart valve. They recommended me to see a childrens cardiologist since they dont specialize in children. i have to get another echo and some other tests done i think. im so nervous. whats going to happen to me??
- You will be fine. Get your tests done and see if there are any special instructions to do or keep. My daughter has viral valve prolapse and leads a quite normal life.
- Q:I am buying a 2004 Ford Taurus tomorrow and want to know the difference between a 24 valve V-6, and 12 valve V-6...Now besides the obvious difference in the # of valves...Is one better then the other???
- The 24 valve is a dual cam engine and has more power than the 12 valve engine. The 12 valve engine is a very reliable engine and is by far the most common engine in the Ford Taurus/Mercury Sable line. The 24 valve engine is the Duratec engine, I believe, and would be considered the 'performance' model. As far as fuel efficiency goes you probably wouldn't notice a big difference on the highway.
- Q:It started leaking slowly so I opened the release valve for about 20 secs than closed it back to see if that would help, but now it leaks even more. So I had to shut off the water that's coming into the water heater and know I can't use the hot water in my house. Can someone help me please!!!!
- you will have to get it repalced.after they get old the spring inside starts to get weak.It will only get worst!Do not do a patch job,its not worth it.
- Q:for a big block chevy,best way to adjust valves and rockers
- w/ one hand spinning the pushrod and the other tightening the rocker arm nut, tighten the nut until you can not spin the pushrod freely, then tighten it three quarters of a turn more. do this to all of the rocker arms that do not have pressure against the valves, then spin the motor 180 degrees, or until the rest do not have pressure against them, and do the same thing.
