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 in my tub/shower stopped working. I did my research on the net to discover the cause and I also went to Home Depot explained the problem. The worker at home depot helped me get the right part I needed to replace the valve stem. I came home, took the faucet handle off and can see what I need to do next. Everything seems perfect and ready to go, except I can't remove the old valve stem. It seems like the old one should just slide out and the new one replaces it. How do I get the old one out without damaging any of the pipes or hurting myself.
- Check back on your website to see if they have the procedure for removing/installing the new stem. These usually have to be turned to allow them to be removed. You should be able to purchase a tool to help you release it. Also, be aware the old stem could be hard to remove due to build-up and/or torn seals. After you get it our, try to remve and deposits in the valve and then apply a little lubricant to the new stem before you insert it. Be sure the lubricant is compatable with the seals.
- Q: im looking at buying a 1995 ford probe, but it has a busted valve in the head, does anyone know how much it would cost to have fixed?
- When you say busted valve, do you mean a bent valve, or a broken valve? if you meant broken valve, i guarantee you my friend, that car is something that you do NOT want to invest your money into. a broken valve can cause and may have already caused all sorts of further damage. this can include exhaust fumes leaking into the cooling system and over-heating the engine, engine cylinder or gasket leaks causing oil to mix with coolant, broken timing belt, blown head gasket, and the list goes on. i HIGHLY recommend you stay clear of a broken valve. if you meant bent valve, this is generally not as serious, but is something to be very cautious of. the best way to check for a bent valve is to have a compression check done. a mechanic can do this, or you can do it yourself if you buy a compression checker. if the valve is indeed bent, the first thing you will want to find out is WHY it got bent. generally this happens because the timing belt slips or the valve has a leak from being stuck open. if this is the case, you might be looking at coughing up $300, maybe a little more, maybe a little less. but before dumping your money on fixing a bent valve, you want to get a professional inspection and make sure that this bent valve didn't cause damage to anything else. i hope this will help you with your question and with your decision on buying or not buying the car. good luck!
- Q: I've found a little beemer that's only $800. I would like to have it as a 2nd car that I'll use in case something's wrong with my main car to loan maybe once or twice weekly to my neices (16 yr. old twins). The seller says it needs a valve job. My question is, will the valve job cost me more than the car?
- almost the work is alot cause you have to practicaly take the engine apart. and its a beemer. look to spend bout 700 on the job (gaskets, labor)
- Q: i bought thie air connector kit and it has y-valves, suction cups and air control valves, what are the air control valves for?
- air control valves are use for any sort of tubing or air pumps/air stones. air control valves are used to control the amount of oxygen/carbon dioxide allowed into your aquarium from the source. usually air pumps come with a air control valve but if not i suggest using one. also when using any sort of air line tubing connecting from the aquarium and out of the aquarium use a check valve! check valves are so important because it prevent water back flow out of your aquarium and into your cabinet,air pump, and of course you floor/carpet!
- Q: and i want to but over size valve seatscan i do it in a 1991 chevy chenynne k2500
- I am assuming that you are referring to a small block chevy or similar engine. Valve seats occasionally crack where the two exhaust valves sit side-by-side. This is the only part where the two exhaust valves are next to each other; the others are separated. This causes high heat in this area and can fatigue and crack. You will need to replace valve seats on the heads which involves boring out the existing seats and installing new ones. You will then need to have new valve angles ground in so that the valves seal properly. While you are doing this I recommend putting in new valve guides, or in a worst case scenario bronze liners (this prevents the start up smoke). To do a set of heads properly you are probably in the neighborhood of $1500 plus and that does not include the removal and reinstallation. If you can I'd recommend a set of World Products SR Torquer heads, you will save money and increase performance. There are also a number of other good aftermarket cylinder heads out there, so the only limit is how much you want to spend. Good luck.
- Q: How much would it cost to get a new valve cover gasket on a 1993 Nissan Quest van?? I know of a van for sale, but they said it might need a gasket soon. How much plus labor, average, do you think it'll cost? Thanks!!
- The valve cover gasket (parts and labor) is about $100 - $200 for the left side and $300 - $400 for the right hand side, but be sure you didn't misunderstand and the failing gasket is actually a head gasket. Those are a big deal: $1500 - $2000.
- Q: where is the shuttle valve located in 03 land rover discovery hse ?

- Your precise, the priority could desire to have long previous away with the previous valve. Your new valve could be defective. in the previous you substitute it however there's a reliable probability your furnish rigidity is to extreme. it must be filling at a extreme rigidity to start with and then as quickly as heated it exceeds the shrink. This sounds like a greater sensible clarification and could greater healthful the priority. while you're hooked to a municipal water furnish they could be in possibility of pay the cost of having a ''rigidity regulator'' put in. or you will could desire to foot the bill.
- 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.
