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: For instance, I am buying some new tires that don't have the valve stems on them, so could I remove my existing valve stems from my used tires onto the new tires? Is this recommend at all? Is it safe? Is it possible? Can this be done? why or why not? thank you.
valve stems are part of the rim only, they cost only 1.50 at the parts store and a tire/service place will charge you 5 dollars on each or include them with the price of mounting and balancing. new ones are suggested always when you mount another tire
Q: Does a faulty pcv valve (Positive Crankcase Ventilation valve) cause excessive exhaust smoke ?
most likely it will knock as well
Q: i have a valve seat pop out and it did some damage my question is can it be fixed i took it to a machine shop the guy look at me with a little confusion he said it cant be done anyone out there have another answer
Replacing the valve seat can be done, but if there is enough damage, it still may be risky. Swapping the head for a rebuilt one is much safer. You turn in the old head as a core, and no one will even care that is may not be rebuildable. They are only $159, exchange.
Q: Hey,Recently purchased a 2006 Audi A4 2.0T Q S-Line. Loving it so far but i can barley hear the blowoff valve if at all. So i am in the market for the loudest blowoff valve. I realize its a very tiny turbo but id still like to hear it and maybe even turn some heads. If anyone can help me out i would greatly appreciate it. Thank you
first off dude, it comes stock with a diverter valve. ive been doing research and so far the best thing ive found to get it loud is to upgrade the diverter valve and get a spacer (all forge) if you dont wanna spend that much then idk what to tell you. chipping your car improves boost so that would help too, also a cold air intake could improve it. all together and youll turn some heads. i have the same car just not s-line mines quartz grey :) good luck bro rick from philly
Q: I have three zone valves, two out of the three don't ignite the gas. Once I turn up the thermostat I see the lever on the zone valves move but no gas ignition. Only one of three works fine. Any leads? Thanks!
the zone valve will turn on the pump. if the water temp is high enough, the gas wont turn on. check the aqua stat to see the temp setting
Q: For example, 2 valves from the modular 4.6 is equivalent to 1 valve from the LS1 which is a bigger valve.
Yes, because the largest 4 valves one can cram in the same cylinder head are smaller BUT provide more area than the largest two valves that would fit in the same head. With valves, the larger the overall area, the better.
Q: So i was driving down the highway and my car just turned off. I turned the key but nothing. My lights were on and everything. I took it to a repair guy and he told me that the timing belt was broken, so i paid to have it fixed. Then he told me something about a compressioner or something, i paid for that, then he told me the valve was bent, so i was pissed and said i wouldn't pay. He was going to charge me about 550. I had already paid him about 250. and i think he was scamming me was I wrong? Does that sound right? Also how would I go about fixing?
check to see if the motor is a no-tolerance engine. You would bend a valve if you broke a timing belt. This is why Honda, Mitsubishi, and many others warn you to change the timing belt at about 60-75K miles. $250.00 for a timing belt installed is on the low side for cost.Call a dealer for the make of car and ask the service manager if the motor is a no-tolerance engine. If it is you will have more cost before the motor is running.
Q: I have a shut off valve under the sink that leaks when you try to turn it OFF. Why is that?I need to fix faucet leak as well. do i need to shut water off to fix faucet? Need to fix valve first. Cant figure out why valve leaks when turning off.
Mr. ? is powerful. replace the close-off valve. the place I stay there's an excellent style of limescale interior the water so shutoff valves purely get gunked up over the years and in lots of situations leak everytime you mess with them. each time I replace or fix a rest room or faucet I purely plan on changing the close-off valve on the comparable time -- a great way much less difficulty than getting the recent merchandise put in and then having to circulate back and take issues aside to swap the leaking valve. I additionally replace the feeder hose connecting the bathroom or faucet too, constantly with the braided stainless style. i could fairly be attentive to I even have put in new factors than have the previous one fail at inconvenient situations and reason injury to the residing house.
Q: Could I get some possible remedies for Mitral Valve Prolapse pain? I currently am off beta blockers, and I need to cope with the mild, moderate to severe chest pain I experience. Female, average weight for my height, nonsmoker, maybe one alcoholic drink a week, exercise at least 3.5 hours a week. What do others with mitral valve prolapse do that helps?
