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: I just replaced my fill valve and all the other toilet components with a universal korky brand kit about 2 months ago and the fill valve is making a hissing sound once the water fills up in the tank. There are also air bubbles that come from the vents on top of the fill valve. I went to the Korky web site and they say that it is a faulty flapper but i checked to see if there is a leak by dropping one of those testers into the tank and there appears to be no leak. Any suggestions?

- Q: I couldn't get a name off the valve as it sits. It has a leak on the top plate and i'd like to replace the valve plate as opposed to cutting the whole thing out and replacing.
- I dont think they sell just the top plate by itself even if you could determine the mfgd. Cut out the entire old valve and replace it. Its not that big of a job.
- Q: Can someone explain to me what lead and lag time are? Also, what are the three flow characteristics? Linear, equal percentage but what is the third. If I wanted to have a minimum stop at 25% on a non-linear valve such as a butterfly valve, how would I achieve this. Obviously you cannot just restrict the valve by 25% of its travel as it is not linear
- Hope this helps in some way... To start the 3 main flow characteristics of a control valve are Liner, Equal percentage and Quick opening (or fast opening). If you interested there are also other characteristics. As far as i am aware the lead time is the time in which a signal is sent to the valve and the lag time is the time in which the actuator moves and closes the valve. The pysical movement. As for your final question the only thing i can think of is to alter the actual size of the butterfly valve or put a reducer before it. Sorry if my information was of little use.
- Q: I just got a new set of tired 2 months ago. The last 3 weeks I've had a separate tire go flat (3 in total). The last 3 the repair company said they were caused by cracked valve stems. So after the 3rd time it happened they replaced all valve stems on each tire. Now today I just got a 4th flat. That's 1 each week for the past 4 weeks. I'm taking into the shop this afternoon for them to inspect the tire. I suspect they will say it's again the valve stem. Any help on what I can do or what to say or ask to get them to fix the problem instead of just putting another bandaid on it? I'm very concerned about my safety and it really sucks that everytime i get into my car, I have to wonder, am i going to get a flat tire today...
- There are only a couple of spots that the tire / wheel assembly is going to leak. Through the valve stem or along the lip where the side of the tire meets the rim. My guess would be that they did not do a good enough job removing debris (corrosion, dirt, etc.) from the rim before they mounted the new tires. With that many flats, you should have them remove the tires and clean the sealing surface. They would prefer not to do this because it means they have to mount and balance the tire again, but it is probably the only way repair the problem. Unless they have a bad batch of valve stems, there is no way that many should fail.
- Q: I need to know how to use a valve spring compressor, the type that looks like a c-clamp. I understand the fork side goes on top of the spring and the circular side goes on the valve to push and hold. There are also two little scoop things in the middle of the fork that i don't know what they are used for. If i can get a step by step instruction, you will get the best answer
- save yourself the hassle and throw that thing away go back to your local auto parts store and buy the l shaped spring compresser should be about twenty dollars make sure vehicle is at tdc remove rocker arm bolt remove rocker arms going valve by valve do not mix them up must go in exactly the same order they came out now lightly tap the top of valve with a rubber mallet will help loosen retainers place compresser on rocker arm stud take r.a. nut and tighten till valve locks fall out or can be removed very small dont lose use compressed air to hold valves in place at tdc sorry that should have been first not hard but not easy to do rebuilt 350 motor from the guts out spent alot of money on spring compressers only to find out the simplest one worked the best the one like u got will give u hell i tried napas version craftsman all of them trust me use the L bar
- Q: 12 valve
- Un plug the vacuum hose on top of the valve, loosen and remove the big tube nut on the bottom of the valve, I have found if you hit it sharply with a hammer 3 or 4 times before you try to loosen it won't break the valve off, once the tube nut is undone remove the 2 bolts holding the EGR valve to the intake manifold. Remove and discard the gasket and install the new valve in the reverse order. If the tube nut still won't come loose try heating it with a torch, if it's really rusted on you might have to replace the EGR tub along with the valve.
- Q: How do you repack an osy valve? Where do you get the packing from? Do you have to shut down the water to do it?
- For most valves, replacing the packing can be done without shutting down the water system. The first step is to back seat the valve. Back seating will occur when the valve is fully opened, and will temporarily seal the leak around the stem. You simply open the valve completely with about 50-100ft-lb of pressure. Once the leaking has stopped, you can remove the packing bolts and nuts on the packing gland. Slide the packing gland up the stem and you will have access to the packing. You may need a packing hook, which is a flexible corkscrew tool, to help remove the old packing. Once you have removed the old packing you will want to repack the valve with new packing by wrapping it around the stem and pushing it down into the valve body. After the new packing has been replaced, it may need to be compressed a little so that the packing gland can be reinstalled. This can be done using two pieces of all-thread rod. Cut both all-thread rods to 6 inches long, making sure to use the same diameter all-thread rod as your packing bolts. Place the all-thread rod through the packing gland and tighten the nuts onto the all-thread rod to compact the packing in the valve. Next, remove the all-thread rod and replace with the bolts. Turn the hand wheel, so the valve is about half way open. Finally, tighten the nuts evenly until all leakage around the stem stops. You may need to exercise the valve a few times to make sure there are no leaks around the stem. Be careful not to over tighten the gland because it can crack and there is no reason to compress the packing more than is needed to stop the leak.
- Q: This is my first tranny install and there is one thing that i really think i f'd up on. I'v been installing a junk yard 700r4 and transfer case into this beater 1990 k1500. Everything is in i'm just waiting on a new throttle valve cable (detent cable) to put it. But me, being my first tranny install, thought that the piece inside of the transmission that the detent cable attatches too.....came out. which i later found out that it doesn't, and that the TV cable just connects to it. I yanked on it pretty good with some pliers, and it never came out, and it still moves up and down. My question is could i have done some serious damage to that peice and the throttle valve itself???? let me know what u think.... thanks!

- Q: i wanna know the role of TOP ENTRY in this definition it's difference with side entry valve.
- Butterfly Valve: a piece that rotates in the pipe 360 degrees Ball Valve- a (circular) plate that goes up and down
- Q: My pressure reducing valve (or restricting valve) was looked at by three master plumbers and they all said I need a new one. My water pressure has been low for weeks. It measures about 100 psi at the outside hose bibs, but it is very low inside and suddenly reduces after you turn on the facets inside. The shower is ok. My automatic sprinkler system is not able to work now due to low pressure. A relative of mine thinks we can just add a handle (as one is missing) on the valve and adjust the pressure ourselves. The repair of the valve is around $500-600! I am told in Texas that we have to have a permit and inspection to repair this valve. Also I was told by the last plumber that came out, that I have to install a expansion tank on my new hot water heater according to code. I'm not sure if that is a city code or federal. Please respond as to information you may have on this problem. The expansion tank is required I'm told when you have a pressure reducing valve for safety, is this true?
- The cost you quoted seems a bit high to me. Mine didn't cost anywhere near that amount in East Texas. A pressure reducing valve acts like a check valve when there is no flow. That is it closes as the pressure rises when you are not using any water. In this condition, the hot water heater can raise the pressure even higher since there is no place for the expanding water to go. That is the reason for the expansion tank. Without the expansion tank the pressure relief valve on the hot water heater can relieve unnecessarily or weep a bit.
