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: The timing belt in my 93 honda accord went out going about 45mph,i then paid someone 150 dollars to put in the new timing belt and it began to shake and he told me that the valves were bent.....i went to a local mechanic and he told me that the valves in honda accords dont bend...is this true?and how much is an average cost to repair the valves and pay someone to do all this?can i do it myself?
- hey, the same thing happened to my car ok, you can fix it but it will take you a lot of time first, you will need to remove all the components such as alternator, exhaust headers , intake and head cover since you paid to get the belt put on, go ahead and mark it with a white out pen so you know where each tick mark goes and you dont have to pay again now you will need a deep 14 inch socket and a torque wrench ( can be borrowed from autozone ) now remove the 14 bolts carefully and lift the head straight up now that you have the head out, it is a good time to replace the head gasket as well take the head to a local machine shop and have it rectified now in a closed area remove the valves and valve covers and put in new ones then its just a matter of putting everything back together I wish I could help you cuz I know it sucks when this happens But go ahead and buy the Chilton book at your local Autozone and it has step by step instructions I took me about a week the first time I did this, and i was just a novice trying to avoid big charges :)
- Q: What is a valve mismatch in cars. code 300, 302, 420. All togather. Mechanic is telling the truth to do tune up and all. Is iT valve itsef? What is a (bad) coild? MITSUBISHI MIRAGE 2000
- Wherever you are get out. You are about to be ripped off. This will probably be too late. I gather the code you gave is the trouble code, as they are called, from the cars obd. The code 300 is random / multiple cylinder misfire. The code 302 is cylinder # 2 misfire The code 420 is catalytic system below threshold bank # 1 Deciphered this means you have a spark plug misfiring in cylinder #2, bank # 1. The misfire is causing a rich gas mixture in the exhaust system that is detected by the sensor and therefore it says you have a catalytic converter problem. I would suggest you replace your spark plugs, if they have a lot of miles on them. Are they the original plugs ? I f so they are probably due. Get out of there and go find an honest shop that will not rip you off. Now that you know the problem they can;t cheat. I don't know what all that other valve business was about but all you have is a misfiring spark plug.
- Q: I have a 66' malibu el camino with a 283 sbc and a powerglide transmission! I have bee noticing a ticking noise on the motor and it miss kind at a rhythm. I took the valve covers off and noticed pieces of metal right by the front of the motor on the head. It is where the #1 piston is. Some of them have kind of a rounded off shape to them. I dont see anything wrong with the springs. but its dark and i cant really see. I also noticed on the even side 2/4/6/8 some of the rocker arms are loose? Some may be loose on the odd side too. not sure, i didnt check them. I found them right where the hole is where im guessing where the oil comes in. What do yall think? It idles kind of rough and i have noticed a loss of power? do i have broken valve springs or something? Thanks for the answers!!!!

- Q: large veins contain one way valves, which keep the blood flowing in one direction. why dont large arteries need similar valves?
- In depth answer is: The Arterial Valves The semilunar valves are mere membranous pockets, and have no tendinous cords attached to them; but on account of the extent of their convex attachment, when their free margin is made tense by the pocket being filled from the artery, the valves can only pass a given distance from the wall of the vessel and are thus held firmly in position. The force of the blood leaving the ventricle distends the vessel and pushes its wall away from the less elastic valve. When the force begins to diminish, the blood passes behind the semilunar flaps and raises them from the wall of the distended artery. The moment the current from the ventricle has ceased to flow, the pockets are forced back by the aortic blood pressure and bulge into the lumen of the vessel, so that the convex surface of the lunated portions of each valve is pressed against corresponding parts of its neighbors. Their union, which is accomplished by their overlapping to some extent, forms three straight radiating lines, and is a perfectly impervious barrier to any backward flow of blood
- Q: Hi guys, Thanks for your advice. RandyK is right, my dad's GP told me that if we don't get the valve operation, his heart will swell in years time and might cause more complicated illness. Just let you know my dad had seen his cardiologists recently and had some scan or tests done. The results will be discuss in next appointment, they suggested that mechanical valve would be used if the operation go ahead. At the mean time I just hope and pray his condition will under control by medication. Wendy, may I ask you how old are you when you had your valve operation? I am too scare to suggest or encourage my dad to do the operation. Because if there is any difficulties or worse ...during operation, I will be the one send him away......If anyone have a relative like my dad's case,(76 years old had valve operation) please give me some advice.. Many thanks
- A friend 65 and I , age 61, had our mitral valves replaced this year. I felt very tired at first. Barely could get up into a pickup truck. My chest felt stiff with difficulty raising my arms. I slept on a couch with 2 pillows awhile. If I laid down flat on the bed, I could not breathe comfortably. It felt so great to be able to lie down flat on the bed after about a month. I had little twinges in my chest occasionally. It has gradually gone away. After 6 months, I feel great and can do all I could do before surgery. I go to water aerobics 2 times a week and walk my dog. Many people are getting valves replaced at ages 60 and 70.
- Q: The hot water shutoff valve to the washing machine was dripping. I removed the packing nut and put in new packing over the weekend. Problem is that the packing nut seems to only go back on at an angle no matter what I do...it may have already been that way though. The valve isn't currently dripping, but I'm not liking the way the packing nut only goes on at an angle. Would it be crazy to keep the existing valve if I keep an eye on it and over time it doesn't drip, or is it too risky to keep this valve given that the packing nut is on at a funny angle? (Local plumbers here in Northern NJ all want around $350 if I were to replace both the hot and cold with a watts single handle valve.) Thanks, J.
- An old saying I like is If it ain't broke, don't fix it!. Even though the packing nut appears to be cross-threaded, if there is no leak, I'd leave it alone. Washer connection stop valves seldom get used. They mostly just stay on, unless you have a washing machine breakdown. I'd just peek at it each washday. If it doesn't leak, I'd leave it be.
- Q: Also please tell me why globe valves are preffered for Landing valves in wet risers in firefighting and gate valves in dryrisers..
- A gate valve is normally used when the requirement is for on/off flow. The characteristic is such that most of the restriction to flow happens in the last 10 to 20% of valve travel. A globe valve is good for regulating flow - so its not either on or off, but there is the whole way in between. If you have a control valve linked to the plant control system, there would normally also be a manual bypass (so you could isolate the control valve but still use the plant). This bypass is normally a globe valve because they can still be used to control the flow.
- Q: I have a 99 Yamaha Warrior 350 and i am needing to take it and get the valves adjusted. I know prices will range from state to state but what would be the average price to take and get them adjusted?? Just the valves not including if they had to change the seals or anything.. Thanks(PS im a girl so put it in simple words!)
- The link below shows what the valves are. The adjustment to them requires loosening #13, and then turning #12 such that the valves #1 2 are within the proper specification. To do this requires disassembly, then measurement and adjustment, and finally reassembly. This can range from 1.5 to 3 hours depending on various reasons. So, estimate 3 x [Labor Rate], whereas [Labor Rate]s vary from shop to shop, and I've seen from $65 to $120.
- 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
- EGR valves are replaced much more often than they need to be. Most of the time the problem is not in the valve itself but in the EGR passages. The actual trouble code would verify that (I am expecting a P0401: Insufficient EGR Flow). The most effective approach is to remove the EGR valve, examine it for really bad deposits, then clean it with carburetor cleaner or replace it depending on whether it looks like it can be cleaned. In any case, clean out all the exhaust side passages. The second source has the usual vague ehow instructions while the third source has a more detailed but vertiginous video. EGR valves are pricey enough (typically $150) to make it worth cleaning before replacing. I personally have never had to replace an EGR valve.
- Q: how hard is it to clean the egr valve on my 2002 Chevy Malibu? if you can give step by step or possibly a website/YouTube video link. thanks
- Cleaning it could make it worse then your experiencing now, but if you want to here's the steps. There are two bolts holding the EGR val;ve down. Remove them, and use a can of carb cleaner to clean the carbon out of the two ports that are in the valve. Reinstall with a new gasket and run the car. If the check engine light comes on replace it. I recently got a EGR valve (not recommended but they work) from a local wrecking yard for my folks '99 Venture 3.4 ltr motor, replaced the one on the van because it was throwing the EGR code and it worked fine. No more check engine light.
