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: Ive been tolding one or more of my valves is/are knocking, how can I fix this. Detail would be great, this is for a F0RD 460, from a 90. I was wondering if I can just buy some used heads(not sure if this comes with these things called valves, haha)but I can pick up some 460 heads, for pretty cheap.. on those and do a full swap, since mine is from 90 i dont know if year would matter. So how can I fix knocking valves., thanks
- Valve noise is usually caused by a bad hydraulic lifter, or a worn cam lobe, sometimes wear in the rocker arms also. I don't think changing the heads would help much in your case. I woud get a good mechanic to listen to it, and tell you first ok, because sometimes, just changing the oil and putting in an additive will stop noisy valves good luck
- Q: my pcv valve tube is broken in half I replaced it with a rubber hose does it have to be whole
- The PCV valve is part of the engines emission control system. It controls the evacuation of the crankcase by applying engine vacuum to the crankcase and introducing the vapors drawn off into the engine. If the PCV valve and especially it's hose cracks or breaks, the engine will have a bad vacuum leak. The engine will loose a great deal of power. Many transmissions have a vacuum modulator that adjusts the shift points based upon engine vacuum levels. Normally low vacuum is associated with WOT (Wide Open Throttle) and so the tranny will delay upshifts when WOT is detected. Astrobuf
- Q: when riding my motorcycle valves start knocking i took to a mechanic and they did not resolve problem. i have baby ed my motorcycle. dint know what to do at this point and time.
- A lot of times you will not hear a valve problem, They tend to tighten up with age not loosen. On sign of a valve out of adjustment is if bike is hard to start when cold. knocking could be loose timing chain, timing chain tension-er needs attention.,Could also be worn drive chain. It will make a popping sound when its stretched out. Some front brake calipers will make a knocking sound, its the pads rattling around between calipers and rotors.
- Q: what are the factors should be know to select a control valve for specified application
- control valve is an uni-directional (non-return) valve, some of the factors to be aware of before selecting it....identify application character, select the valve size, select the valve end connection, piping layout and valve orientation , maintenance requirement , actuation requirement , initial cost ..etc..
- Q: For a project I need to know the ingredients of a product I use and I decided to use valve oil. All it says on the sticker is petroleum distillates. Can someone give me the ingredients? I need it to have atleast 5
- Valve oils use proprietary formulas so it is unlikely you will be able to find out an exact composition. The basic ingredients of petroleum (as opposed to synthetic) valve oils are light machine oil (kerosene), mineral spirits and fragrance.
- Q: My 4.0 L V6 2002 Ford Explorer has this plastic casing on top of the intake manifold...some of the hoses (brake booster, etc) are actually connected to the plastic casing, now how can i replace my pcv valve?
- Try okorder
- Q: My third valve is always sticking, despite the fact that I oil them thoroughly every other day. It scrapes the sides of the case when I take it out/put it in, it's almost as if the valve is too big for it. Often times it will stick and I'll have to unscrew it and physically pull it out for it to be functional again.I've inspected it, and the inside looks just like the others which are fine. I've tried washing it, oiling it, and putting a trace amount of vaseline on it. What is the problem?
- Check the spring and plastic valve guide on top of the spring. I've seen these stick and the results are quite annoying, but once the spring moves up and down freely, so will the valve.
- Q: instead of just buying a replacement, is there an easy way off the valve to check if it's still good?
- dio, yes, if your sprinkler control valve is not opening a zone valve in the automatic mode, then manually turn the solenoid on the zone valve counterclockwise, it sprinklers come on , then you have confirmed a bad solenoid. these can be purchased seperately or another oprtion is a complete zone valve dio, well, if water is flowing thru then the solenoid is not sealing on the zone valve body itslef. unless there is debris between the solenoid washer and zone valve body, then sounds like a bad solenoid...
- Q: Is it safe to remove the butterfly valve on my 94 celica 1.8l st?
- Um...no Why would you want to? Also, a 94 celica should be fuel injected, and not have a butterfly valve. What do you call a butterfly valve? I call it a moveable plate that controls the air flow for the intake on a carburettor.
- Q: Hello, I have a 1990 BMW 525i.I would like to paint the valve cover where the BMW was written between a set of lines.I think I require a heat resitant paint for doing this.Can anyone advice the brand which will be best suited for this job.Is it advisable to chrome plate the valve cover.?with regards,natarajBahrain
- The BMW valve covers are made of aluminum. You can repaint these valve covers using hardware store spray paints without any problem from high temperatures. The valve cover should be removed and degreased with something like Gunk. The spray paints will not adhere to any parts with oil or grease contamination. The acorn retaining nuts should also be painted the same aluminum color. You should take the acorn nuts off their studs and insert them onto a piece of cardboard where you can overspray two or three coats of aluminum paint. Chromed acorn nuts do not look good with aluminum color valve covers. Do not attempt any underhood painting with spray paint unless everything within 4 feet is carefully masked off. Be very careful with spray painting things like thermostat housings, coolant hoses, and spark plug wires looms. You can buy 4 mm chrome plated flat washers from many hardware stores for about 5 cents apiece. I think you will need about 30 flat washers for the 2.5 litre engine. Good luck. You can try the engine paints if you like, but they are much more expensive and not any better looking. If you wanted to paint your exhaust manifold, I would suggest the high temperature paints designed for 1000 deg. C. temperatures. Some hot rodders use enamal coatings on the exhaust manifolds. BMW exhaust manifolds are very hard to see from under hood viewing as they should have asbestos heat shields to protect spark plugs, gaskets, and plug wires from excessive heat.
