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.

FAQ of Swing Check Valve:

Q1:I can’t find the type of steel check valve which I need. what can I do?

The chart above only lists out some common composition of steel check valve parts.We may provide other different parts material composition according to the customer's request or the actual valve working condition.


Q2:Which certification do your products pass?

  Our products are in accordance with ISO 9001ISO 14001API 6AAPI 6DTS CEAPI607/6FA/BS6755.


Q3:How can I place an order?

  The only one thing you should do is to tell us the sepecification about type quantity and  mode of transportation, then we will send you quotation within 24 hours.




Q: Is there a more technically correct name for a valve that slowly opens, allowing increased pressure in a water line without blowing the end off?
I've always known them to be simply called motorized valves, but they aren't specifically made to prevent instantaneous pressure build up. They are usually installed as a convenience type of thing and in lieu of solenoid valve which WOULD be an almost immediate full pressure situation, but any valve other than a solenoid activated one will allow for slow build up of pressure. A motorized valve just lets you do it automatically and you don't have to be right at the valve location to open it. Al
Q: The water shutoff valvue has a slow leak where the hose connects. Its right were the hose to the tank connects to the shutoff valve.....I also noticed when I close the shut off valve it doesnt stop the water completely. Does the whole setup need to be replaced, and if so, is it difficult? Or will just replacing the hose correct the leak?I figured the constant running wasnt a huge deal if there was no leak because you leave the water on anyways, so there is always constant water pressure there.
as for the actual leak replace the supply tube to the toilet (it's called a closet supply tube)and don't get the braided one with the rubber gaskets already made into it i've repaired thousands of dollars of damage caused by them.get the poly supply tube,toilet supply nut, 3/8 compression nut and 3/8 teflon ferrule.(ferrule goes tapered end into valve)if the valve has to be replaced it depends on what type of water lines your house is plumbed with to determine difficulty of replacement.try a new washer---turn off water to house and drain best as possible.open toilet supply valve all the way and remove stem by unscrewing packing nut (the one the valve stem comes out of)you have to turn handle and packing nut to completely unthread it.replace washer and re-assemble. good luck.(p.s. hold valve still with opposing wrench or pliers so as not to twist pipe in wall or floor.
Q: My 99 accord has been smoking bluish white smoke out of the exhaust only at high RPMS- 5000 and up, but NOT at lower RPMS. Obviously I rarely go that high, but I've feared the worst. I've checked the coolant, its green without contamination. today a mechanic discovered that someone installed the wrong pcv valve on the car- the one that belongs on the v6 model, and that it is somehow larger. the mechanic suggested it was possible that this was the cause of the smoke- the oil was getting into the intake manfold, and into the cat, and that when the engine is at higher rpms, and the gases/ heat increase, it burns up the oil in the manifold/cat. He said IF that is the cause it should clear up in a week or so. Does this sound to good to be true? or is it possible? the car does have 160,000 on it, but i've owned several hondas with much more mileage that didn't smoke at all.
could be the PVC or it could be blow by past the worn rings ... get a compression test done ... this will let you know each piston chambers state of health
Q: I think on old AC units They had a different valve than the shrader. It might be called a king? Anyway, I can't get my gauge to read the pressure. The needles don't move at all. How can I measure, refill this type of HVAC?
Unless you are EPA certified, you have no business checking the refrigerant in old AC units. If you get caught, you could face a hefty fine.
Q: Compare and contrast stenosis and regurgitation (insufficiency) in terms of the functional abnormality associated with the valve leaflets and their effects on hemodynamic parameters such as stroke volume.

Q: where is the shuttle valve located in 03 land rover discovery hse ?
The shuttle valve is a part of the brake modulator this problem is addressed by the replacement of the brake modulator and that's a $1,500.00 dollar part plus labor but I believe that they sell a shuttle valve repair kit for around $100.00 dollars.....
Q: How do you remove a richdel sprinkler valve, when I turn the body of it, it doesn't unscrew, it just turns in place.
is it the valve your trying to remove, or the sprinkler head? if its the valve, there will be two pipes, one in and one out, just unwind the thread at end end of the valve, If its the sprinkler itself, then there should be a pipe under the sprinkler(swing joint) just grab the whole body and unscrew ( make sure you grab the whole sprinkler and not just the top, you may have to dig around it
Q: Do most V6's have 24 valves? What are they for? (brief description would be fine)
Valves fit into the top of the cylinder to allow the fuel/air mixture in (inlet) and exhaust gases out (exhaust) on older engines and a few more modern ones there is one of each to each cylinder. Later engines use two of each so that the cylinder can be fueled and exhausted more quickly. They are timed to open and close by means of a rotating shaft with eccentric lobes (camshaft) operated by the cambelt (or chain) from the crankshaft.
Q: ok...i want to find a valve that controls air pressure so i can let it out in 2 different ways for my pneumatic potato gunwhat websites or stores sell this (not home depot)
You might have to register on the site to order online. It is free. You can call them and order the catalog. It is free also. Hope this helps Email me if you want me to look it up in my catalog. Don't break any windows. Wingman
Q: One day i was cleaning my trumpet's third valve. when i tried pressing the key it was goig inok but near the end it gets stuck and gets unstuck like a second later.how can i fix this problem with out spending too much money?
instead of the standard cheapo trumpet grease, try a more generic brass instrument oil. also make sure you aren't tightening the valve screw cap too tightly. it's not a good idea just keep tapping it. also, unwanted moisture can create a seal that will sometimes inhibit the valve from popping back up. get it dried out as much as you can. also, don't use too much of anything - the oil, the grease, etc - excess will keep it from popping out too.
