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.

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 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 possible for car manufacturers to make 32 / 64 / 128 / 512 Valve Car Engine just like in a PC CPU? The highest valve I saw so far is 16-valve engine. Just asking :-)
- I'm sure they could if they wanted to. The problem is the more moving parts you have the problemms you will have and the more it will cost.
- Q: i wanted to know what is the actual difference between check valve (non return valve) and globe valve?
- Check valves are designed to prevent back flow. A globe valve is used when the ability to throttle and control the flow is desired. The globe valve can be positioned at anywhere from 1% to 100% flow. This allows for very precise control over how much liquid will be allowed to flow through the valve. There is another type of valve called a gate valve. The gate valve can not be positioned with such precision as the globe valve and it is used when flow rate is not as important.
- Q: My question mainly pertains to Electric Motor-driven Motor Operated Valve Actuators.

- Q: Hey guys Itook my car to mechanic because my engine light was on and the code showd that it was unsufficient egr lift or something like that....they had changed the egr valve before so this time they said there was carbon build up and they cleaned it and my car runs great now. i don't have problem with accelaration and the engine doesn't stall when i stop, BUT the light came on again and still shows the same code. I am sick of it!!! anybody knows what else could it be? It's 94 honda accord with 140 000 miles on it.
- Hi Val, It sounds to me like the repair shop made a mistake here, they replaced a part without addressing the condition. If you had a fault for ERG insufficient flow , it would be caused by excessive carbon build-up in the intake manifold or the upper intake plenum, depending on engine. If you had a problem with stall at idle and a fault for excessive EGR flow the culprit would be loose carbon particles lodging in the EGR valve pintle and keeping it open. In either case the carbon needs to be physically removed, this would involve removing the intake manofold and or upper plenum Good Luck!
- Q: I took my 2nd valve out to wash it (i couldn't find my oil, but it worked fine) and I've tried making the number face the mouthpiece, yet it still is messed up and won't let me play a lot of notes.
- 1) Try this first and if this doesn't work, go to #2. Oil the valve's body and gently put it back into the cylinder without screwing it in yet. Then, turn the valve until it clicks, and make sure it is really seated correct. Some trumpets have two clicks, and one is not the right one. So, you have to get the right click - which tells you that your valve is seated right. When your valve is seated right, then screw it in. 2) If you don't get a click when you spin your valve - look at the tubing on your trumpet and line up the holes in your valve with the tubing. When the valve is up, it will line up with 2 holes of the tubing, and when it is down it will line up with 2 other holes in the tuning. So, you can determine the correct positioning of the valve by looking at the tubing on your trumpet. But this is a last resort. I've never seen a trumpet where the valves don't click when you turn them.
- Q: Can a leaking car tyre valve be repaired/ replaced, or is it more viable to get a new tyre fitted with a new valve?
- The actual valve can be unscrewed from the valve stem and replaced. If t's the valve stem that needs replacing this is done from inside the wheel/tyre combination. It may be possible to deflate the tyre, push one side inwards off the rim and get to the valve stem, but it's a lot easier to take it to a tyre depot and have it done properly. The real difficulty with a DIY job is getting the tyre sealed on the rim again. With an air line it's easy to put air in fast enough to reseat the tyre, with a foot pump it's almost impossible
- Q: I have a hot water oil burner. I need step by instructions on how to replace the pressure relief valve.Do you know?Please help me.
- First off shut it down and let it cool off turn off the water source and the power to the unit. You will need either a large adjustable wrench or a monkey wrench to remove the valve if there is a drain pipe connected remove it first. Check the temp stamped on the old one and make sure the new one is for the same temp. you will need Teflon tape wrap around the threads several times to form a good seal.tighten and put the valve at the same angle it was before. Turn everything on and run unit to check for leaks. Good luck
- Q: i have been told that a bad EGR valve (exhaust gas recirculation valve) could cause a car to buck or hesitate in mid range speed at low rpms, thats what my car is doing. i work at autozone and i used our code reader and there was a code that stated EGR flow malfunction anyone else have this problem ever? please help me! i dont wanna spend the $120 if i dont need to!
- There is a device called the transducer that connects to the EGR system via vac lines that doe's have a electronic plug on it that could show up under codes as if the EGR valve is faulty but isn't.If the EGR valve has a electronic plug on it then it could be that it's faulty. Hope that helps and best of luck.By the way I ran into that same problem and it was the transducer.Keep in mind that at the big do it yourself auto wreckers you should be able to find several of either of those parts.
- Q: What is a foot and check valve what's the difference between the two?
- Check valves are designed to prevent back flow. A globe valve is used when the ability to throttle and control the flow is desired. The globe valve can be positioned at anywhere from 1% to 100% flow. This allows for very precise control over how much liquid will be allowed to flow through the valve. There is another type of valve called a gate valve. The gate valve can not be positioned with such precision as the globe valve and it is used when flow rate is not as important.
- Q: I don't know the principle of operation of the butterfly valve. Can I control the percentage of opening by an analog output from the PLC?
- You can purchase operators for some butterfly valves for either on/off operations or to modulate but the flow characteristics of a butterfly valve makes is a very poor modulating control valve,
