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: 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: There has been brake fluid leaking below where the Master Cylinder was and pinpointed that the leak was at the base where the steel lines and proportional valve intersect(kinda sprays out out like if a seal is bad or someone didn't tighten enough). Any way to fix this or replace? Vehicle is a 1988 Plymouth Reliant (2.2 liter) Auto, no ABS.
If you are not familar with brakes I wouldn't suggest tackling this job yourself. You will need to take the line off in question to condemn either the prop valve or the line. I have never in my life seen the line itself leak but I guess it's possible. The valve is a dealer item only, whatever you do, dont buy it from a junk yard. After replacing the valve, if that is what the problem is, most likely you will need to get a brake power bleeder to get all the air out of the system. I would estimate through a shop and the typical mark up on the part, shouldn't be more than 200-225 parts and labor including the brake flush, good luck.
Q: Around the relief valve there is water leaking it is not the valve it's self or the threads it's around the out side of it. The valve is on top of the heater
Is the valve open? If not - I would open it - the pressure of the tank is forcing water out around the valve - by opening the valve you will relieve some of the pressure. Also - turn off the power and call a plumber in the morning- your hot water tank can blow up - not good.
Q: I'm in the process of replacing my dishwasher but I have a problem. I followed the water line from the dishwasher to under my sink and found a red valve that was completely straight, so I turned it to the right as tight as it would go and tried removing the hex nut connecting the line to the dishwasher. Maybe i'm wrong, but there is a lot of water coming out of the line and I don't think it's supposed to. I easily filled up a bowl you would use to mix cakes and it was still going! So, I turned the valve back to straight across thinking maybe someone else turned it off (my dad), and tried it again but the same thing? What am I doing wrong and what should I do to solve this?
If you have cut off valves below water lines going to the dish washer,turn them off. There should be a hot and cold water line. Red is used to designate the hot water line and blue for the cold water line. If all else fails,turn the water off at the water meter,this turns off the water to the whole house.
Q: Hi. im wondering what reed valves do and can they put on a 4-stroke engine or not???Thanks for your help.Dune.buggy5
Reed valves were popular when you could get a street two-stroke bike. They allowed air to flow only one-way. I think Yamaha even had a nifty rotary valve thing that squeezed the air that the piston sucked so it would flow a bit faster into the combustion chamber. With a four-stroke, I don't think there's any advantage to complicating the air flow with a reed. That's what cams and valves do. You need to burn more fuel to get more power. There are several ways to do this. You can do this with more RPMs, more fuel/air mixture, or a larger displacement. But that's about power, not necessarily a reed valve.
Q: ok so the water main that comes into the basement the valve handle snapped off so how do i shut the water off so i can replace that valve? I called the water company and they said they cant shut off the supply to the house because it is private property and we have to call a plumber if so how can they shut the water off and on if we dont pay the bill?
Near the curb on your street you will see the Concrete box with the metal lid. Take the whole lid off. The valve should be inside. You need a tool for this or you can do what I do. Put a Big crescent wrench on the valve. Then take larger Chanel locks and grab the crescent wrench and turn a full 180 degrees. Check your sinks for the results.
Q: Leak in Heart Valve ?i was told by my doctor to to do a ultra sound on my heart a few weeks ago, wehn i finished the ultra sound the lady that did the scan asked if i had any type of heart disease in my family, and i responded that i dont, she said that i have a leak in my heart valve, but that was all, i dont have an appointment with my doctor til two weeks from now, i THINK i feel shortness of breath, but i feel like this may all be because im scared ...... main thing is has anyone had this or know anything about this is it dangerous, deadly ? should i be scared ?
It depends on what valve is leaking, how much is leaking, and for how long has it been leaking. Wait for the physician to evaluate the echocardiogram. Technicians are often wrong or limited in their evaluation, as they are not trained in in-depth evaluation of echocardiographic studies like a cardiologist. Make an appointment with your doctor to discuss the results. You said you think you have shortness of breath, make sure you mention that when you make your appointment. Only your doctor will be able to determine if it is related to your heart, or due to anxiety, or from something else.
Q: My sump pump shut-off valve is very noisey. I wrapped insulation around it, but it still clunks. The clunk can keep me awake.

Q: The water shut off valve that is under my sink in the bathroom is leaking and I need to replace it. I am wondering if I need soder the new one or can I just put some thread tape around it.
More ofter than not the innards of a valve will deteriorate and start to leak, when that happens its best to replace the valve. Since you ask about soldering the shut off valve, I'm going to assume that you have a copper line coming out of the wall. Older valves required soldering, nowadays there is a compression fitting that eliminates the need for soldering. Once you have the correct size of the pipe turn off the main water supply. Remove the old valve (may need to take a hacksaw or tubing cutter, if its soldered on). Then slip the new nut and compression ring over the pipe. Next bring the valve up to the pipe and tighten the nut to the valve. Once the valve is secured on attach your lines, preferably new replaced lines. Open the valve line, and then turn on the main water line and check for leaks.
Q: I have a WRX. slightly modified. im getting some upgrades here soon. clutch, brakes, and catback exhaust. i have a blow off valve i bought a while back, but found out it was illegal here in cali. if you know about blow off valves, then respond. is it worth putting on? what are the consciences of having one illegally if noticed by cops? all i know is that it sounds bad ***! :)
a blow off valve only sounds good and will cause you to run rich and blow black smoke when it releases boost other than that there is no actual gain in hp just a cool sound
