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: Okay, I got a 347 stroker and I noticed a spot that was leaking under one of my valve cover gaskets. So I went ahead and bought new gaskets. But before I replaced the gaskets I noticed that my valve cover bolts wasn't tight. So I basically went out for nothing and get new gaskets. Anyways since I couldnt return them, I went ahead and changed the gaskets. And I tightened all of them pretty tight. And I noticed that I still have an oil leak at the same valve cover gasket at the same place. Why is this? I also used cork gaskets, did I tighten them too hard? How hard should you torque valve cover bolts/
- I have see one time that a car had blown valve cover gasket. It leak very well and Touch on Exhaust Madifold. It cause fire. Engine is High milages. Engine make blow by through piston and cylinder. Bypass gas cause Press gaskets or seals to make oil leaks. Other thing is loose vaccum for brakes. It make hard to press brakes. Like air leak. OR Rubber valve cover gasket getting dry up, and start brittles. Its ten years old, So go and replace valve cover. If you know how, That will be great. Do it asap Than Sorry.
- Q: I am working on my riding mower Briggs and Stratton 15.5 OHV. After replacing my headgasket my intake valve did not move when I turned shaft by hand. I took it back apart and believe I have my pushrods positioned correctly but cannot seem to get the rockkers back over the valves and rods. Maybe its because I am a girl and just need to man up but I thought it should be easier. Anyone got any tips?
- Okay, here we go. I have been doing this for 150 years, so I think I know why you are having the problem. The piston must be at Top-Dead-Center (TDC) on the FIRING stroke. Both valves will be what is known as On The Rock. That is or means the push-rods will be resting on the camshaft inside the engine where there is no lift (bottomed). The best way to find this out is to look at the flywheel and see where the magnet is in relation to the ignition coil. The engine actually fires twice (it's just the way it is), but if yo see the magnet on the ignition coil then chances are you are either at TDC on the compression stroke or BDC on the induction stroke. Confused yet? Let's make it easy to tell the difference. When the piston is at TDC the piston will be at the to p of the bore and the magnet will be on the ignition coil. The valve push-rods will be at the same height. This is when you fit the rockers. As you can see there will be two nuts or a single nylock nut that has a nylon insert. If you have the nylock nut then then just tighten the inlet to 0.007 and the exhaust to 0.010. The same applies with the two nut system, except that when you have set the gaps you have to spin the locking nut down and hold the set nut (the first one) and then tighten the other nut down tight to the set nut. But I guess you knew all this, eh. Good to go, eh. I hope I might have been some help. mmalky: 50 years fixing small and large lawnmowers.
- Q: non-return valves
- ..?..non-return valves..? I will assume that your 'non-return valves', are what is also known as check valves. Check valves allows flow in one direction only. These are used wherever you need to prevent backflow into the system, or to maintain a charged circuit with fluid, until you choose to unload(depressurize ) it. Now, why are they used in discharged lines of salt water, basically to prevent backflow....reason not known, here , requires usage info.
- Q: my valves got dirty long story how do you clean them
- Remove the valves, wash them and the horn in warm (NOT hot) water with liquid dish soap. Dry with a clean towel, then oil and reassemble.
- Q: I know nothing about toliets - so please bare with me. The water valve underneath my toliet is dripping and I have to turn off the water in order for it to stop. It's really annoying to have to turn the water on when I want to flush it and have to empty out the container that is catching all the time. I think it has something to do with the valve itself and I'm PRETTY sure something behind it needs to be tightened - Has this happened to anyone else? What did you do?
- There is a small nut around the valve handle on the valve tighten this one
- Q: in engines otto cycle
- Larger valves allow for more volume of fuel/air mixture to be introduced into the combustion chamber. They give an engine more horsepower but can compromise efficiency in the long run. I would rather have smaller intake valves and larger exhaust valves. The advantage to that is better flow of the exhaust. 40 percent of an engines total horsepower and torque comes from exhaust flow. If a person wants more fuel in the chamber all they have to do is change the camshaft to one that has a longer open duration. This will let the desired amount of fuel/air in where you need it.
- Q: My car hesitates on the highway 55 m/h and up after about 20 minutes of highway driving, I unplugged the EGR valve to see if it still hesitates, but the problem went away after disconnected the Egr, so is it for sure that the valve is bad? Just wanted to make sure there's no other component that could be also be bad. I have a toyota avalon 1997.
- You might be able to get the valve cleaned by spraying cleaner in it or by emersing it in solvent. Check the repair manual and consult with an experienced mechanic. I don't even have a ball park figure of what a new one would cost.
- Q: my mid eighties GM full size car with a 305 just started to have a problem...it runs fine at idle.....runs rough/sluggish at speed......when I take my foot off the gas there is a fast rattle in the engine.........and sometimes the engine likes to idle fast.....I replaced the catalytic converter last year ...........so now I am thinking of changing the egr valve....there is no service engine soon light on and this car is a mid eighties so no obd 2 system on this car......any other ideas? thanks
- EGR valve got sooty,and rusty and dirty and then they dont work right. They either dont open or they get stuck open and cause the car to run lousey. If the valve has been i the car since the 80's it is probably about time to either clean it or change it. do you have haynes or chilton manual for the car? they explain alot.
- 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)
