1. Structure of Check Valve Description
This product is designed and manufactured fully in accordance with API Spec 6A wellhead and Christmas tree equipment standards,and can thus be used interchangeably with the products manufactured at home and aboard,which tally with API Spec 6A specifications ,or used to form a complete system.
This is a type of check valves which rely on the pressure of working medium to get meal-to-meal sealing between the core and body(seat). The higher the medium pressure,the better the sealing performance. It is always able to withstand the pipeline pressure within the value cavity.
The body of the valve is forged with alloy steel,which has solid mechanical properties and is able to withstand high pressure in safty and reliability.
The bonnet and the body of the valve are connected with blinding bolts. Sealing washers are used to seal up the bonnet and the interior wall, which reduces the space in between to a minimum (designed as 0),thereby considerably minimizes the erosion of the bolts and the bolt holes,caused by erosive media,and also decreases the load taken by the bolts.

- Q: Anyone know how to stop this from happening? I have gone through 4 since March.
- are you sure its the egr valves going bad or not the egr solenoids causing you to get the code,that will make it appear that an egr has gone bad when it really hasn't,good luck.
- Q: 2003 Ford Focus SE2.0L SPI EngineAutomatic Transmission 145KPerfectly maintained since new!One of the pistons had snapped, yes the actual piston, it didn't mess up the walls, but I am hearing a LOT about these dropping valve seatsI intended to do an entire rebuild with a kit, but did it break BECAUSE of a droppedvalve seat?I don't know because I don't know what that isHelp is appreciated
- highly unlikely , depends how the piston is broken often when revving too high the piston top will separate at a ring groove nothing to do with valve seats
- Q: I have 3 such valves in the line and none seem to be able to move past 10/4 oclock position and water remains on. Is there a way to adjust valve? Seems there is slot for screwdriver in center of valve.
- I'm trying to understand what kind of shut-off this is. Most PVC valves are 1/4 turn levers, or ball joints with a T shapped handle, in both cases, when the handle is perpendicular to the pipe, it is closed/off when it is parallel with the pipe it is open/on. Other valves like a brass cock will be a round handle that you turn clock-wise to close the valve and counter clock-wise to open it. These type will turn many full revolutions. If you can't move the valve, it may be that calcium deposit has glued the inner valve into position. You might want to lightly tap it on all sides with the handle of your screwdriver as you try to turn it. Don't put to much force on it though because you will likely break it. Don't waste your time trying to unscrew the handle, that won't make a difference...
- Q: Compare and contrast stenosis and regurgitation (insufficiency) in terms of the functional abnormality associated with the valve leaflets and their effects on hemodynamic parameters such as stroke volume.
- stenosis means thats it difficult to open the valve to allow a full ejection of blood. regurgitation is caused by an insufficient valve, in which the valve does not close all the way, and thus allows blood to flow backwards. For instance, the two AV valves (mitral on the left, tricuspid on the right), are prevented from prolapsing by chordae tendonae, which are connective tissue fibers attached to pieces of cardiac muscle (papillary muscles) on one end, and the edge of the valve on the other. If these chordae tendonae break, this may cause blood to flow back into the respective atria during ventricular systole. Valvular insufficiency and prolapse will cause diminished stroke volume. Valvular stenosis, on the other hand, is typically caused by a buildup of material on a valve which inhibits its movement. This buildup could be many different things, to name a few: valve calcification due to hypercalcemia, bacterial adhesion and growth due to sepsis, plaque (cholesterol bound with free radicals) buildup on the valve, a fibroma, etc... If the valve's opening is inhibited, and it does not open all the way, there will be a diminished blood flow into whatever chamber is next in the sequence. If an AV valve is stenotic, the ventricles may not fill properly, and preload will be low, which will lower ejection volume. If the semilunar valves are stenotic, then the ventricles will likely hypertrophy because they will need to work harder to force as much blood out, because blood entering the ventricle must equal blood leaving the ventricle with each heartbeat (starlings law of the heart).
- 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: Valves regarding WC's
- David, tercir is wrong. A flush valve is THE valve inside of a toilet tank that allows water to refill the tank when you flush your toilet. That flush valve has a float on it so when the tank refills to a certain point, the float shuts the water off. A flapper valve merely HOLDS the water in the tank until you flush the toilet. The flapper valve is the thing on the bottom (inside) of your tank that covers the water outlet. When you flush your toilet, that flapper raises the water that is currently inside of your tank, is what refills your toilet bowl when THAT water goes down into your sewer system. OK?
- Q: Beneath my kitchen sink are two shut off valves for the water; one for hot, one for cold. The hot water valve has never successfully stopped all water flow, so we've always resorted to shutting off the main line. Well, now that's not working. We shut off the main water line to the house, all water everywhere is non-functioning except for the hot water pipe beneath my sink. It's now causing the faucet to constantly stream water, so it's something we have to resolve ASAP. I'd like to avoid calling a plumber, but my knowledge in such areas is very limited. Can anyone give me any decent suggestions? For the record, I did take apart the faucet fixture just in case, thoroughly cleaned it, and replaced all of the washers I had access to; but we only just bought the faucet in September, so I can't see a worn washer as being the problem. I also tried to tighten the nut behind the handle on the valve. It didn't effect the dripping.
- Hot water valves always go bad before cold water, ashot water is harder on the rubber and plastic parts inside valves. That said, turn off the water at the main and drain whatever hot water faucet is lowest in the house. If you have one in the basement, that is best. Turn on the hot water in the kitchen so the air can come in at the kitchen and the water can run out in the basement, or bathtub, whatever is lowest. Next, the valve under your sink will likely have a hexagonal nut on the side that has a line going to the faucet, and it will probably screw directly onto the pipe on the other side. If this is the case, just loosen the nut, pull the line off of the valve, then unscrew the valve. Take the old one with you to get a replacement so you can compare to make sure you have the right one, and then reassemble it the way it came apart The nut may be attached to the sink hose. Once you've reassembled things, then remove the stem on your faucet above the sink. That valve is also not stopping the water or it wouldn't be running all the time. If it is a two handle faucet, then remove the hot water handle, and remove the nut underneath that holds the stem into the faucet. Take the stem with you to the hardware store and they can help you find the right washer or rebuild kit. Replace it the way you found it once the new washers etc are installed. If it is a single handle faucet, then there is probably a screw that has to be removed under the faucet spout before you can unscrew the handle and remove it. Take out not only the stem, which is built into the handle, but also the rubber washers that are sitting in little holes inside the base. Take them with you to the hardware store. The little cup shaped rubber washers may also be under the stems of two handle faucets. Those cups have to go in with the wider opening down and the smaller hole upward.
- Q: does a 1975 chevy pickup 2wd has a proportioning valve? If so how does it work and the signs it is bad? my truck has disc/drums brakes?
- Yes they do go bad! It sounds like that is your problem. You can try bleeding the proportioning valve with a brake bleeding gun, making sure to open every valve then re-bleed the brake system this will eliminate the possibility of a air bubble in the proportioning valve. I have changed probably ten or twelve of these things in my ventures.
- Q: If someone is not born with heart valve disease... can a teenager or a 12 year old develop heart valve disease?
- Yes, anyone can have heart valve disease. It is unlikely though. Usually if a 12 year old has an abnormal heart valve, then it is secondary to a congenital heart defect (something they were born with.) Infection of the heart valve (endocarditis) can occur in any age group and lead to an abnormality in the function of the valve involved. Rheumatic heart disease is also possible, but not common in the developed world since the regular use of antibiotics. Good luck.
