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:

1The 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: The automotive machine shop who is working on my Corolla head and block said that one of the valves was severely burnt. What causes burnt valves???
What Is A Burnt Valve
Q: 1998 Ford Crown Victoria LX 4.6L Use 89 Octane BP, Shell, Chevron gas. When the engine is under stress(acceleration or going up incline) the engine sounds like the valves are chattering. I can increase the rpm's and the chattering goes away. Had the same problem with 95 Thunderbird 4.6 and have heard other ford cars going down the road with this problem. Air leak? Don't really want to use higher octane due to gas prices and possible engine damage. Also, in the thunderbird, i used a bottle of octane boost and the next day a valve spring broke. Was the octane boost a possible cause?
it is not valve chatter, it is called Pinging, it is a fairly common problem, what it is caused by is hot spots in the engine, or by overly advanced spark timing, i would check your base timing, perhaps even back it off a degree or two, i would also run a bottle of marvel mystery oil, or gm top engine cleaner through a vacuum line to burn out the crud that has built up, the sum total of these repairs: about 15 bucks, the savings: your engine! as for your t-bird, it was the pinging that broke the valve spring, not the tank of hi octane. hope this helps
Q: Among butterfly,ball,needle and gate valves which is used mostly in pneumatic system?
It depends on what sort of system you are operating. Most butterfly valves leak, a few don't. Ball valves are instant operation, and don't normally leak. Needle valves are used for fine control of the flow rate. Gate valves are quick to operate, and don't normally leak. On aircraft pneumatic systems, butterfly valves are common, where a leak is permissable. Where no leak is permissable, slide valves are used, which have rubber seals.
Q: The pump is working fine on the presta valve on my back tire, but it is not working on the other presta valve. It seems like the the presta valve isn't sticking out far enough out of the tube for the pump to be able to lock in on it. What could be causing this?
If is it a deep V wheel you need a tube with the proper extension for the value, or a presta valve extender. Next time you replace the tube measure how long the value is in mm and get a tube with a longer valve stem.
Q: its a vauxhall movara van and i need help im trying to found out wether the valves are broken all the springs are upright and all level , so does this mean there ok ? or not ... thanks
The valve can be bent or broken under the head. Just because it looks right up top only means the stems are OK. The stems are usually OK, even if the valves are bent and broken. If it's making horrible valve noises and you're not sure, it's probably got a bent valve. Only way to know without pulling the head is to do a compression test.
Q: When my son was three I switched Dr's for him. The new doctor said has he always had a heart murmur I said no that's the first I've heard of it so we went for test. Anyway heart specialist did all tests said my son had Bav a valve disorder in the heart. He said it is very common. However everyone I've ever talked to has never heard of it. My question is does anyone have this what is your story and have you had to have your valve replaced. My son is very healthy active I'm just worried. Any help would be greatly appreciated....thank you!!
A bicuspid aortic valve is not necessarily a problem - a normal aortic valve has three cusps, and your son only has two. Having only two cusps is not a big deal. The mitral valve in the heart naturally has only two cusps, so three cusps are not needed for a heart valve to function. The advantage of three valves is a slight increase in efficiency, but the difference between a normal valve and properly working bicuspid valve would only matter to a professional athlete. If the aortic valve closes almost completely, there is nothing to worry about. Since he has a heart murmur, its possible that it is caused by having only two cusps, but people with three cusps commonly have murmurs. There is no reason to get the valve replaced simply because of only two cusps. What matters is the level of aortic valve regurgitation. If regurgitation is not significant, your son has a normally functioning heart. Even if he had a moderate or high amount of regurgitation, it still might not have enough effect to warrant surgery. There are tests to measure regurgitation.
Q: Can anyone tell me what to do if i know that I have the type of valve stem that was recalled TR413chrome?? Will they replace them for free since they are a recall or do I have to dish out some more $$ to fix the problem??? The company that sold them to me is in Florida (Wheelmax) and I am in Mass. Not sure what to do to avoid having to pay out more $$ to have them replaced...any help is greatly appreciated
Get okorder Take care.
Q: My check engine light is on in my 1999 Toyota Camry XLE...I went to autozone and they told me it was my egr valve BUT they did not tell me if it need to be cleaned or replaced. How can I tell if it needs to be cleaned or replaced
its not an expensive part a new one will help mpg
Q: My friend is having 3 valves in her heart replaced with pig valves. Her dr said that putting in human valves raises the risk of her body rejecting them but wouldnt your body also reject a part form different species? And if they only last a few years why use them at all? shes all freaked out about the surgery so I dont want to ask her too many questions
I'm not a cardiologist, but I suspect that pig heart valves are a lot easier to find and replace (if rejected) that human heart valves. Pigs are geneticaly very close to humans (go figure), till not long ago we were using porcine insulin for diabetics. The heart valve replacement is probably only temporary, meanwhile she might be put on the waiting list of heart transplant recepients. Once a matching human donor is found, she might be have to undergo a complet heart transplant. They dont replace only the human valves, they usualy replace the whole heart.
Q: i have a yamaha trumpet. i got it brand new and it is 3 years old. I recently did drop it and i have a tiny dent on the last turn to the bell. after that they started sticking . There are no dents on the valves or casing surrounding them. i brought them to Quinlan and fabish and showed them the sticking they replaced the valves spring padding and the such. They also did an ultrasound cleaning i think it is called . they are still sticking. Please any think that you can suggest i showed my band teacher who suggested going to Quinlan and fabish. Then my trumpet teacher who said i need to oil more after the cleaning please help
Check that you are not putting sideways pressure on your valves when you press them downwards. Even on a good horn this sideways pressure can cause friction between the piston and the valve casing. Avoid this by arching your fingers a little, depressing with your finger's tips, and avoid the pinkie finger ring entirely. Tying your pinkie up in that only restricts your 3rd. finger's freedom of straight downward movement. Over- lubricating the valves can be as bad as too little oil. Do the whole warm bath treatment that you would normally do to clean it, add 3 drops to each valve, work horn for a few minutes, wipe valves with very old (washed heaps of times) t-shirt: then finally 2 drops again. If this doesn't work, get a trumpet specialist teacher to take it home for this treatment.(You might not be bathing it right). Failing that, check my web site's repair section. Good Luck!
