Product Description of Ball valve for heating supply:
Technical introduction
★The ball valve is designed as fully welded structure,which can prevent the leakage of medium.
★The valve seat is floating and spring-loade.The seal is made of soft seal materials of PTFE+20%C and Viton B.The seat is tightly abutted against the ball surface by the pressure of a spring,so that even if the media is in low pressure,a reliable sealing can be assured for the ball valve.Double piston effect and double seal(two-seal seat)are adopted in specially designed valve seat to realize double sealing,which makes the tightness of the ball valve more advantageous and the operation easier.
★A floating ball is adopted for DN15-DN200,and a stem and trunnion ball is adopted for DN200 and above,which can ensure the accurate position of different size ball.In other words,the sealing performance,low torque valve and operability can be guaranteed.
★The sealing of the stem is fulfilled by two replaceable O-rings and packing consisting of PTEE+20%C or flexible graphite,as the packing seal material,is fire proof effect,and is specially suitable for fuel gas systems.
★The materials used for the valve body and pipelines are the same(carbon steel or SS steel),valve body and stem adopt SS steel and the packing adopts PTEE+20%C which is corrosion-resistance or flexible graphite.

- Q: I recently had an echo and they said their was a slight tricuspid valve leak but it was 19 and anything less than 20 is considered normal. I have no clue what that means. Does any one have and clue on what scale she was talking about. Also she stated that the machine are so sensitive these days that the majority of people are found to have some sort of leak. Is this the case??????
- The tricuspid valve is a valve in your heart that, like any other valve, makes the blood flow in only one direction. When your heart pumps blood into your body, this valve is normally closed so the heart only pumps it in your arteries, and not back in your veins whence it came. When this valve doesn't close shut completely, a little quantity of blood leaks through the little opening there. You can see this with an echocardiography which you said you had done. Yes, the value of 19 is really low, and the fact that the limit to normality is 20, so you're close to it, doesn't mean that you're almost sick. Keep in mind that these limits that doctors have are some guidelines, and they all have a safe zone. Plus, this is not the kind of lesion that evolves, it doesn't mean that as the years go by the little space in your valve will get bigger and bigger - nothing of that sort. It is probably a thing that you had since forever, and you will have it the same your whole life with no problems at all. In the end, let me say that if you are brave enough to go to a doctor (many people aren't, and that really sucks), you should be brave enough to ask him/her what they mean when they say certain stuff, without worrying that your question might be stupid or already answered. You didn't go to med school, and it is the doctor's duty to explain to you what is happening in your body just as it is to diagnose and treat you. Best of luck!
- Q: How does a deluge valve differ from a standard alarm valve in a wet system?What are differences from a standard wet pipe system regard alarm trim and NPFA codesAlso if an existing system, over 2000sft, (pipe sched method) has no siamese connection, and I am adding addtional heads via the same pipe schedule method - Am i required to upgrade the riser/alarm trim to include a fire department connection? - (re:NFP13, 2002)
- Normally sprinkler can classify as either wet type or dry type. In which under the Wet type system you will have pre-action, deluge and Dry pipe. Of course in anycase wet pipe is the best due to its economic reasons. Indeed, ppl spec for dry type because of afraid fault alarm, accident damage, low temperature (maybe less than 10 degree C) of production area and so on and forth. Generally, deluge valve can be manual or automatic. It doesn't have sprinkler bulb head. Upon detection of fire, responsible person shall operate the alarm valve manually. If automatic features is installed, Heat and Smoke detector will detect the fire and trigger the alarm valve to open and the water flow in. You need to calculate the Design Density to size up your tank properly. In your case of just only an extension of building and not construction from empty land, you may need to study on the existing fire fighting system to which standard it has been designed from. From there, you can extend by maybe adding another alarm valve, and so on and forth. Mechanical Consultant will able to assist you in this. You may write to me and tell me more about the form, feed and funtion of the building so that i can provide more ideas on this....
- Q: does anyone know how much work it would take for a 1998 Mazda 626 (2.0L MFI DOHC) to change a bad intake valve?what work would be necessary and what kind of price are we talkin?
- if you have did a compression check and know for a fact that the valve is bad the head has to be removed and then checked for leakage and cracks before you install it back on,those was bad to produce small cracks between the valve guides,if it checks ok then have the valve replaced,the cost should be about 600-700 on doing this one,that was a good engine those cars had in them,good luck.
- Q: I really like the sound that a blow-off valve makes when they are in audi tts. So I was wondering if I got one for my '02 225hp Audi tt if it would damage the engine in any way. I have read that diverter valves are better, but I want the sound of the blow-off valve. Also any recommendations on blow-off/diverter valves would be great.
- Blow off valves are nice, but they aren't terribly good for your car. The main problem is that when the turbo isn't running, that open valve will suck unfiltered air into the engine and can seriously damage it. Blow offs are also pretty inefficient as you lose a good portion of the air in your turbo system. The best thing you can do is just get a good Forge diverter valve. Well made, looks nice, and will add a pretty decent amount of performance.
- Q: I need a ball valve that when you shut it off it sends a signal to a light that indicates that it is off.
- Shouldn't be a problem. all that's needed is a valve with elect contacts on valve stem. should be able to get one with two sets of contacts for on and off...
- Q: How many valves are involved in th etypical 4-stroke cycle? Is it the intake and exhaust valves only? If my car engine has 12 valves, how many cylinders does it have?
- For basic internal combustion you only need two valves, one for intake and one for exhaust. The four strokes are referring to the piston moving up and down in the cylinder, one to take in gas and air, one to compress the mixture, one during combustion and one during exhaust. Common cylinder amounts for cars are 4, 6, and 8. Some Volvos had five cylinders, and exotics can have more than 8. Modern engines can have more than two valves per cylinder but the standard is still two, so if you have 12 valves you most likely have a 6 cylinder engine.
- Q: I'm drawing a complete diagram of the heart, but I'm unsure of the positions of the different valves. I know there are the pulmoary valve, the aortic valve, tricuspid/right AV, bicuspid/left AV, semilunar valves, mitral...but I know there are several names for some of them, like I think the mitral and the bicuspid are the same...but there are so many sources online I don't know which to believe. If anyone knows for absolute sure the right names and where they are it would be very appreciated if you could help :)
- the bicuspid is the same as the mitral valve it seems like anatomy has 12 names for everything In anatomy, the heart valves maintain the unidirectional flow of blood in the heart by opening and closing depending on the difference in pressure on each side. They are mechanically similar to reed valves. There are four valves in the heart (not counting the valve of the coronary sinus, and the valve of the inferior vena cava): The two atrioventricular (AV) valves between the atria and the ventricles, also called tricuspid and bicuspid. The two semilunar (SL) valves, in the arteries leaving the heart, also called pulmonary and aortic. This I know for sure. Drawing pictures always helped me keep it straight and I just got an A in anatomy. best of luck to you
- Q: does that mean it doesnt work?, how can i tell if the egr valve works still?
- Not sure how to answer. First the vacuum line going to your egr only has vacuum under certain conditions and never at idle. If you have an egr code/problem.... email me with code/syptom and vehicle info i'll try to help further. :)
- Q: Is there a difference between the atrioventricular valves in the right side versus the left side of the heart?Is there a different between the pulmonary valves?
- Right Atrioventricular Valve
- 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.
