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 have a curtis toledo compressor at my house. While moving it a helper dropped it on its side into the tank and broke off these 2 valves off the very top of the compressor. They had a copper line that ran off both of them and went over to the auto on/off switch, I'm guessing that's what it is. Where can I buy these or at least what are they called?
- They are the unloader valves. Look online for places that sell parts for air compressors.
- Q:need a different pump for? Is this some improvement on the old valve?
- Dita is correct. You do not need a new pump. Most of the new ones (ones you'd find at a bike shop, probably not Wal Mart pumps), will handle both. The newest ones have a smart head where you just plug in the valve, flip the lever, and the pump figures out which valve stem you have. On slightly older pumps, it is a matter of switching the pump head internals around. On the really old pumps (or really cheap ones), you need a brass or alloy adapter that threads onto the presta valve and converts it to schrader.The schrader valve uses a spring to close the valve to prevent air loss. Presta uses the air pressure itself to seal the valve.
- Q:How do I adjust the valves on a 96 Blazer, 4.3 V6? When we tighten them to torque specs there is no compression, then when we loosen them and get compression, they loosen up to loose after its been running...any help!, THanks!
- THEY AREN'T ADJUSTABLE!!! The problem is the lifters are filled with oil and they won't compress to the point where the valves close all the way. You have to torque them to the proper setting, then turn the engine by hand untill the valves (lifters) have all had time to bleed down in the open position. It's a pain but you have to turn the engine till a few valves are open, then wait a few hours, mark those valves or write them down on a piece of paper, then turn it till some other ones are open, etc etc.. When you put lifters in new there's always some air in them, but when you take the pressure off a used one the spring pushes the plunger inside the lifter up, and it sucks in oil and becomes overprimed. By letting then sit for a while in the open position, the valve spring will push some of the oil out of the lifter, and allow it to reset to the proper adjustment next time the valve closes. Hence the term Hydraulic valve lash adjuster (lifter for short) DON'T WORRY YOU DON'T NEED A CAM OR NEW LIFTERS. THAT HAS HAPPENED TO ME DOZENS OF TIMES.
- Q:where is the heater control valve on a 1996 volkswagen passat
- i'm no Ford fan, yet a Mondeo resources of a similar fee might want to be my determination. Neither Passat or A4 are fairly good, and service prices for VAG diesels are astronomical. once you're insistent on an A4 or a Passat, ?a million,00 is going to get you a finished smash till you're prepared to spend a lot of time being dissatisfied by utilising the final public of autos on the marketplace.
- Q:eventually needed mitrial valve replacement or Valvuloplasty? It is also sometimes called Acquired Valve Disease, Aortic Valve Disease or Mirtral Valve Disease. Any information would be very helpful. I was not born with this condition if that helps at all.
- Balloon valvuloplasty is a procedure in which the stenotic heart valve is stretched open using a balloon catheter inserted through a artery in the groin. Obviously the best deal if it works to resolve the problem. The valve replacement is a procedure that requires open chest and open heart surgery. Heart bypass circulation, significantly pain management and some time in the intensive care unit whilst usually in an induced deep sleep. Check out the website below. Optimistically the valvuloplasty should have you back to excellent health.
- Q:What do I do to make my valves stop ticking? And what makes them tick? its a 94 Acura Integra with a 91 LS motor, 105,000 miles. If I get a new engine head will it stop ticking or the ticking has to do with the block?
- you just neeed to have the valve lash adjusted, 105 is nothing on the B18, my integra had 250k+ before it got totaled and it was still running strong, you dont have to replace the head. and you will have to do more work if your gonna put a GSR on the LS block
- Q:Is there something else i can use to lubricate my trumpet valves besides valve oil....I don't have any at the moment but really need to lubricate the valves.
- I found vasaline worked if you're on a tight budget, but baby oil works better.
- Q:Hi, i bought an xr250r 2002 model. I rebuilt the engine and put in new exhaust valves. After i did this proper compression in the motor came back and it wasnt blowing smoke anymore. I took it for a 'run-in' ride, and noticed that the engine was quite noisy. I guessed it was the valves needing adjusting. I got numbers for the valve clearences which were: .004 of in inch for the exhaust valves and .005 of an inch for the air intake. Now i have done this the compression in the bike is enormous, it is barely possible to kick over, and the motor is very noisy, there is a loud ticking noise which im guessing is still the valves. Is all this normal considering i have just rebuilt the engine, put in new valves and hardly ridden (one 50km ride)? I would like to keep riding it to run it better to see if the motor loosens up, but im scared to ride it as it is. Any advice would be greatly appreciated.
- .004 is a bit tight for an exhaust valve? usually this is nearer 10 thou. It is better to have slightly larger clearances to the tappets/ valves than to be too tight and risk burning your valves. You do not mention the decompressor! I'm sure your bike should have a manual decompression lever if not an auto retard unit on the cam shaft to allow you to atleast crank the engine up to TDC on the compression stroke. I suspect that is where the noise problem is coming from, either that or you might be one tooth out on your cam shaft gear allowing the piston crown to kiss the valve when it is open...hence explaining the very hard to turn over!! but see my other comment too! What ever It is time to remove the inspection covers and re examine the whole set up. BTW the bike should be an UTTER PIG to kick over compression without a decompressor!! as it has a very high compresion ratio. expect to be standing up on the kick start if you are less than 160 lb (11 stone) 78 kg
- Q:I am going to replace the EGR valve on my 99 Pontiac GP with the 3.8. It needs replacing(has already been cleaned twice) and keeps popping the code for it. Anyways..my question is: after its replaced what do I need to do to reset the codes or computer? Someone told me to unhook the battery for a hour and that will do it???? Is this true? Any help out there?? THANKS!!!!!!!!!!!!!!!!!!!!
- a great type of the time its not the EGR Valve, this something else. Do you no what code or codes have been discovered ? i've got seen the O-ring lacking on the percentvalve alot and this journeys a EGR code, verify the percentValve for the O-jewelry or while the engines ruining open the oil cap and verify to verify if theres a great vacuum there. if so the O-ring is lacking.
- Q:Electric Hot Water Tank Pressure Release Valve Leaking, Why?
- did you recently increase the heat settings or change a thermostat? an increase in temperature can cause the pressure relief to go off a little...but usually only when the temperature gets up there (160-180oF) which is uncommon for electric. Unless the valves are shut off above the tank, the piping system should handle any pressure increase in an electric tank. Do you have a buffer tank on the hot water side? (usually only when you have hydronic heat) it could be saturated or pre-charged too high. If none of the above are probable, you may just have a bad pressure relief valve, I've changed one before, had to turn off the cold water and open up a cold tap to let all the pressure out of the system, bleed off the hot water until the pressure valve didn't spit out when I opened it, unscrewed the plastic downpipe from the valve(some have it, some don't) and remove/replace it with some teflon tape on the new one (20 bucks or so from the home depot)
