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:It has been known that although tissue valves have lower rates of thrombotic episodescompared with mechanical valves, they are difficult to procure, and their longevity has not yet been proven. Is this true as of 2007? Thanks for answering.
- Tissue valves do last as long as mechanical valves in most cases. Most of those are porcine valves, and some are bovine. The majority of those are used to replace the aortic valve. The mitral is almost always replaced with a mechanical valve.
- Q:I was getting something to burn and smoke up this empty 2 liter bottle for my friend's brother's science experiment. We didn't find any wood, so I took his trumpet valve oil, dripped some on a piece of wood that wouldn't burn and make it smoke up. Does burning valve oil have any negative side effects as opposed to say, regular oil? I shouldn't have been so lazy and just used vegetable oil or something haha....
- Valve oil is basically just mineral oil and various other ingredients. You can buy pure oil, and it's also the main ingredient in baby oil and other medicines. Nothing wrong with burning it.
- 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?
- Yep - the right atrioventricular valve, also called the tricuspid, has three cusps. On the other hand, the left AV valve, also known as the mitral valve or bicuspid, has two cusps. The bicuspid can withstand more pressure than the tricuspid.
- 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:I was diagnosed with a VSD and a Biscuspid Aortic Valve and my doctor has started hinting towards sugery. I found out that the only reason i haven't had surgery yet is that it is stable enough to wait until technology improves so i am not left with a large scar. i was just wondering what this surgery would entail and if anyone has had it. I am 19 years old and kind of worried about it...
- My daughter was diagnosed with this same thing when she was 10 days old. It has been a miracle that she has not needed any medication or surgery. She meets with the cardiologist 1 time a year. They told me if she stays as stable as she is she will not need surgery. Maybe if your condition stays as stable as it is now, you will never need surgery. I know that when they repair a VSD they do open heart surgery and put a patch over the hole that is in your heart. Sometimes these patches fail and they do surgery 2 or 3 times and it is common. I know that Bicuspid Aortic Valve is an inherited abnormality and that it becomes more sever in your 30's and 40's. Most patients with bicuspid aortic valve whose valve becomes dysfunctional will need careful follow-up and potentially valve replacement in their third or fourth decade of life. Patients with bicuspid aortic valve should be followed by cardiologist or cardiac surgeon with specific interest in this valve pathology. Average lifespan is similar to that of those without the anomaly. In many cases, the condition will cause no problems. However, especially in later life, a bicuspid aortic valve may become calcified, which may lead to varying degrees of severity of aortic stenosis and aortic regurgitation, which will manifest as murmurs. If these become severe enough, they may require heart surgery. I hope this helps and good luck with everything.
- Q:I have a T4-T10 and L5-S1 spinal injury and I recently found out that my tricuspid and my mitral valves leak. I have never had heart problems before I got the spinal injury. Do you think the valve leaks could have been from the trauma when I received the spinal injury?
- I wouldn't think the trauma would directly injure the valves. Were you in the hospital for a long time following that injury hooked up to IVs? With IV catheters there is the possibility of bacteria entering the bloodstream and causing damage to the valves. Maybe that is why you developed valve issues. Also I wonder if there is the possibility that the massive immune and inflammatory response generated by that much trauma to your body may have caused some damage to the valves. I've never heard that happening, but I imagine it's possible. Also it may just be coincedence and you may have had the valve issues before but never had reason to check them out. A small leak in the heart valves is very common as people get older.
- Q:Hi,I have just bought a Northface Hammerhead and for some reason when biting on the bite valve no water is being released. Does anyone have any idea why this might be, or can tell that I am missing something obvious. Thanks very very much.
- North Face Hammerhead
- Q:I need to find a solenoid valve with the following specifications:2-way, 1 inch nozzles (both male)needs to be able to handle the pressure from a CO2 tank (~1000 psi)needs to work with 12vdc less than 10 ampsits either a solenoid, or some other type of valve which will release the CO2 when we tell it to electronically
- The leading maker of solenoid valves is ASCO. Their website is shown below. If a valve that fits your application exists they probably make one. If you can't find a suitable solenoid then you need to consider a pneumatic valve operated by a solenoid valve. That is a common solution for a problem like yours. As to the male connections. If they are not available then you can just use a pair of threaded fittings (pipe nipples) to change the configuration.
- Q:I am a 55-year-old female going in for mitral valve replacement surgery, and I need to decide on which valve to get: bovine or mechanical. If you have any experiences or know anyone who's had either of these types of valves placed in their bodies, please elaborate on the experience. I want to know the pros and cons of each.Thank you.
- Mechanical valves require lifelong anti coagulation. This can cause problems of compliance (Forgetting to take the medicine), longer time to heal for cuts, and potential internal bleeding problems especially for women. They have a very long life. Current bio prosthetic valves have improved considerably in durability. They do not require continuous anti coagulation. They do tend to calcify. This may not be a problem 55 years and above. These valves also have better blood flow characteristics. These are the general considerations. Individual bio chemistries vary widely. Your surgeon and cardiologist are the best fit to suggest what is best for you.
- Q:I bought a plastic ball valve from Lowe's just a couple days ago and it is stuck, I haven't installed it in anything but it wont budge without a pair of channel locks. I tried wd-40 but still nothing, should I return it or keep working with it? and if I keep working what should I try?
- === take it back and get another valve .... if it doesn't work freely in your hand then the valve will be a problem if you install it ---- working with pvc you should use the purple glue that is waterproof and it is a good seal and no leaks when you have
