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:the water coming out of the kitchen faucet has been getting weaker and weaker this week and now it flows a 3 out of 10. The thought it might be time to replace the faucet/faucet washer. I went to turn off the water under the sink.. hot and cold valve but water still comes out of the faucet with enough force aka not a dip but free flowing water. I turned the red handle valve to off as well but same thing. I am totally thrown off. HOt and cold water still comes out of faucet. When I push the faucet handle down, the water does not stop right away as well but slowly stops. No problem water into dish washer. I have replaced numerous faucets but I can not figure how water is still getting to the faucet after turning all 3 valves to shut off position. I still think it might be the faucet but now I am not sure. I am close to calling a plumber but really do not want to do that. thx
- it could be that you have a bunch of gunk in the end of your faucet. The thing on the end should unscrew and you will find lots of sand and junk in there. also when you turn off the water there is still a lot of water in the lines which may be what your seeing.
- Q:I think the piece leaking is a valve;it is one solid piece of copper with two tubes, one which is a half inch that connectsinto the incoming hot water and then a small outgoing one that connects to the faucet and I don't know how to find a replacement part .. I think it is a Delta but I am not sure ... the house is 10 years old but where can I just find a valve instead of replacing the entire faucet if I don't know what the make or model is ?Any websites with pics of replacement valves for Roman Tubs??
- Remove the valve and take it to a plumbing supply store. Home Depot and the like may have what you're looking for; but you're more likely to find it at a plumber's supply. They are the only ones I've ever found who carry odd bits.
- Q:We have an ejector in the basement for an in-law apartment. When the check valve kicks in, it can wake us up from a sound sleep. A very loud thunking. Any ideas?
- the check valve would be installed just outside of the crock vertically. The noise I doubt is from the check valve itself. I'd guess it is the pump shutting off and the pipe isn't fastened securely, so it bangs. Check to make sure that the run of pipe leaving the crock is fastened securely. if this is the case the only other option I oculd think of would be to re-position the check valve on a horizontal run of pipe as close to the crock as possible. Most check valves I have seen for ejectors are compression type, it will be messy but not to complicated. Keep a bucket handy, when you crack open that check valve you may need it. Flush the toilet until the pump kicks on a few times, this should clear out most of the nasty stuff. You may also need a short piece of 2 pipe and some couplings to make up for the space of the check valve. If you can hear the water flowing out when the pump kicks on and don't hear it draining back into the crock when it shuts off, the check valve is probably still good.
- Q:pls. tell me the differnce between isolation and block valves and also where it to be used .
- The two terms are used interchangeably. They are valves that are used to completely interrupt flow as opposed to a valve that is used to throttle or control flow without stopping it.
- Q:This valve has flow indication embossed on their body.
- the gate valve is a very important one in flow measurement and also used to help the measure of flow. for example if you know the pneumatic comparator operation, you can easily under stand the gate valve. the gate valve is mainly used for to adjust the float in the tube to zero position or the clearance value.
- Q:I want to know if a person with multiple leaking heart valves left untreated, is in any more danger than someone with a single leaking heart valve.
- yes, it is more dangerous! have someone take that person to the ER right away or call 911!
- Q:I have a 2001 Chrysler 300 m. About a year ago it cut off on the interstate. The mechanic told me my timing belt broke and i had three burnt valves. The timing belt is already fixed, but I was wondering what parts were needed for the other. also what is the estimated price to fix this?
- Burnt valves or, far more likely, bent valves. Either way, you'll need to basically overhaul the top end - you'll need to replace the bad valves and the top end gasket set along with any machine work that may be necessary. Estimates will vary greatly from facility to facility and also from different areas. To get a valid estimate for your locality, you need to get local estimates.
- Q:Dr says I have a leake heart valve. Should I be concerned?? He doesn't think so but I am worried. Should I get a second opinion? I am 53 and a diabetic. Has any one ever had this problem?
- go back to the doctor with your list of questions and don't leave till they're all answered.
