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.

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 9001、ISO 14001、API 6A、API 6D、TS CE、API607/6FA/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 it supposed to go on or only in cases when the power goes out??? I bought this pump and the directions are horrible!!! There isn't room for both the air stone and the check valve!! How does this stupid thing work???
- Check valve designated that it lets air go in one direction and stops water from going in reverse direction. For example if your airline gets disconnected from airpump by accident and drops on floor water won't gets syphoned out frmo tank to floor. You'd be surprised how much water can end up on floor in this scenario ;-) In order to install check valve you have to cut airline somewhat in halfs and put your checkvalve between pump and airstone. Arrow shows direction in which it passes air.
- Q: I am looking at getting a baritone horn of my own, but am not sure what compensating versus non-compensating valves are?

- Q: I did a compression test, and I have a broken valve. everything else is in perfect condition besides this valve and I have carbon getting built up in one of my pistons. Can I run the car like this? What cause this from happening what was the cause age?1999 Ford Explorer 4.0 OHV with 146k,miles
- Let me guess, cylinder number 3? (passenger rear) Let me explain. In the last year, we've had three 4.0 Explorer's in our shop with a hung valve on #3. The last one we had in the shop, the valve broke without warning and broke the rod which cracked the block on the drivers side. They said it was running fine one second and made some noise and it started missing. It wasn't even knocking when it came in. Something about the #3 on those.
- Q: Mitral valve prolapse have impression on lifetime?please answer with source
- Mitral valve prolapse (MVP) is the most common heart defect in population. The prevalence of MVP is about 0.6–2.5%. The occurrence increases with age, and the highest is in young woman. MVP is diagnosed by transthoracic echocardiography when displacement of mitral valve leaflet(s) above the annulus into the left atrium during a systole is present (Fig. 1). The clinical symptoms of the disease are connected with instability of the autonomic nervous system. Fig. 1 Two-dimensional echocardiographic long axis parasternal view of mitral valve prolapse. MV mitral valve, LV left ventricle, LA left atrium, RV right ventricle, Ao aorta Such a large population of patients becomes a problem of social significance, and it is extremely important to determine the influence of MVP as a chronic disease on patients. That is why our trial to evaluate the health-related quality of life (HRQOL) in children with MVP was undertaken. There are many publications concerning MVP in adult patients, but no study on their quality of life has been found. The literature concerning HRQOL of children with heart defects is not very extensive; the authors analyzed the problem of patients with serious conditions, such as hypoplastic left heart syndrome, transposition of the great arteries, pulmonary atresia, tetralogy of Fallot and non-complex heart defects, like ventricular or atrial septal defect [1–3]. The aim of our study was to evaluate the quality of life of children with MVP and the impact of clinical symptoms on HRQOL.

- Q: Its stuck to an angle where the metal parts of the wheel block the air pump from letting it secure itself around the valve so i cant put air in, it all comes out the sides, i dont want to have to replace anything for i dont know much about bikes, but any solution to my problem? Thanks
- What causes the valve stem to get like that. is from riding it with an almost flat tire with very little air in it. . Let the all the air out of the tube ,. pull and tug on the tire to rotate it on the rim until the valve stem is standing strait up again. Then refill with air. But often when you ride with low air, it ends up making a hole in the tube.
- Q: How do I know if the valve seals need replacing? From what type of smoke can I detect?
- A 'leak-down' test is the best bet, shows where in the system the compression is leaking and if it's around the valve stems than for sure the seals need replacing. Can't judge it by the smoke accurately as oil could be slipping past the rings also.
- Q: Help! I've got this leaky CPVC valve in a new plumbing setup for a water heater. It only drips when open. :( It's going to be a real pain to replace it. Is there any way to tighten this thing up? It looks like there is a plastic pop off panel on the knob for the valve but I'm not sure. Thanks for any help!
- Turn off the main water to your house. Turn that valve to open. Then tighen the nut on it (slightly), see if the valve will close , if yes; then tighten it a little more, then see if the valve will close. If yes - that should do it. If the nut is so tight that the valve will not close, then loosen the nut just a tad. That should do it, ......... now, turn the valve off. Turn back on the main water to your house -- and see if that works.
- Q: I heard there are really fine valves, does someone possesses thoughts where to buy these goods? I heard about them on TV. Anybody alive?
- Yes, okorder
- Q: This trumpet has been in storage in its casing untouched for about 5 years. I took it out and tried to play it but only air comes out and no sound. The 2nd and 3rd valves are hard to push down. What do I do to fix it? Thanks!
- Dis is a pretty common problem. The valves are in the wrong valve case or they are turned aound in the case. Take each valve out and check the number...... most have a number stamped near the top, or on the part around the spring. Get them in the right place with the notch in the case matching the little peg on the side of the valve and all should be well. By the way, if you can't get a buzz on the mouthpiece the whole problem is you alone.
- Q: how to replace a valve cover gasket on a 98 pontiac sunfire 2.2. engine?
- First off, you remove the PCV hose and unscrew the plastic nut that retains the PCV valve. Next you remove the air intake tube from the throttle body and the air intake housing. Now locate the bracket on the side of the throttle body that contains the throttle cable. Remove the 2 bolts from this bracket and remove the cables from the throttle body. You should now be able to remove the valve cover from any obstructions. If you are not cleaning the valve cover, there is no need to remove the PCV valve. If you are cleaning it with soap and water, take the PCV out. The gasket is one piece and rubber, but you may find it a pain to keep the gasket in the groove on the valve cover, so you might try some yellow weatherstrip sealer to help hold the gasket in place. Let it dry for a little while before reinstalling the valve cover, so the gasket doesn't 'roll' out of the groove on the corners, or it will leak heavily. Good luck.
