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:had a water heater put in after that i have low hot water pressure it get hot but goes to a low stream.when i try to adjust gate valve it keeps turning
- freeze the line coming to the valve, with a co2 fire extinguisher, or dry ice, then swap the valve, and let it thaw
- Q:Hi. im wondering what reed valves do and can they put on a 4-stroke engine or not???Thanks for your help.Dune.buggy5
- Reed valves were popular when you could get a street two-stroke bike. They allowed air to flow only one-way. I think Yamaha even had a nifty rotary valve thing that squeezed the air that the piston sucked so it would flow a bit faster into the combustion chamber. With a four-stroke, I don't think there's any advantage to complicating the air flow with a reed. That's what cams and valves do. You need to burn more fuel to get more power. There are several ways to do this. You can do this with more RPMs, more fuel/air mixture, or a larger displacement. But that's about power, not necessarily a reed valve.
- 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:How do I test to see if my gas valve on my wall heater is working or not? Please don't respond and say call a pro.
- There's a rubber diaphragm inside the water regulator it must be deforming cause of water condition . By changing that washer will start work. I recommend call a pro to do that.
- Q:My question mainly pertains to Electric Motor-driven Motor Operated Valve Actuators.
- The motor drives a gear operator on the valve and is limited in the degree to which it operates by a set of limit switches so it doesn't over run or over torqued the shaft. This arrangement typically also has another set of limit switches that indicate the open or closed position so the person controlling the valve will know its position. This type of operator is typically used on ball, butterfly or plug valves but can be used on gate valves.
- Q:Is a leaky heart valve considered to be a form heart disease?
- Hello, Yes, it is. Obviously the leak is still within the arteries, - no blood is leaking out of the heart, - any leak is only in the backwards direction of blood-flow. One function of the valves is to stop blood which has just been pumped, from falling backwards again to where it came from. As soon as the pumping action stops, the valve has to close to lock the pumped-blood in its new forward position. If any blood leaks back through the closed valve, that is called regurgitation of blood, - and the closed valve which is leaking is described as incompetent or insufficient, in medical language. Sometimes newborn babies are born with a heart valve (or valves) that leak backwards, having not been properly formed in the womb, - or sometimes the valve (or valves) are damaged in adult life by some disease, - for example, infections like Rheumatic Fever or Syphilis, (both rare nowadays). I hope this is of some help. Best wishes, Belliger retired uk gp
- Q:My friend is having 3 valves in her heart replaced with pig valves. Her dr said that putting in human valves raises the risk of her body rejecting them but wouldnt your body also reject a part form different species? And if they only last a few years why use them at all? shes all freaked out about the surgery so I dont want to ask her too many questions
- Hello again. The valve I have implanted in me is porcine. Pig valves are sometimes used for a few reasons. First of all, they are much easier to get a hold of. Waiting for a human valve can take a long time. Secondly, there is less risk of rejection. These two reasons make a porcine valve better than having a human valve. You can also have metal valves, but when you have one or more of these you must take crazy medications for your entire life. With porcine valves, no extra medications are needed. So, porcine valves are really the best option. Like I said in a previous answer to one of your questions, I had my surgery when I was 16. I'm 22 now and doing alright. My valve is expected to last 10-15 years, so I expect to go under the knife to have it replaced when I'm 26-31. Unfortunately I have other issues and will have to have the surgery done earlier, and they'll probably change the valve while they're in there already. As far as I know, porcine valves last just as long as human valves. Whichever you have, it's going to clog up eventually anyways.
- Q:Ok guys I have a 70 4 bolt main 350 40 over. I have a lunati 292 cam 230 at 50 degrees. 480 lift. The kit says 1.5 rocker ratio. No valve adjustments needed. I just boight edelbrock aluminum heads summit number 5089 64 cc with 185 intake runner . And comp cam roller tip rockers. That say 1.52 ratio. All my decks on the engine and heads are stock not shaven. I have speed pro pistons with .125 dome. Im using standard felpro gaskets. Ok my question is will standard lenght pushrods work for this build. They are 7.794 length. And will my piston head clearance be ok cause of my domed pistons. and do I need to find rockers that just say 1.5 ratio to make this work or are 1.52 the same. Thanks
- Your fine with the roller tip 1.52's
- Q:My car had white smoke coming out from the exhaust.After talking to my mechanic, he said that the valve seat is faulty in which i suspected earlier. He also told that my car need to be overhauled. What would a faulty valve seat cause my engine?
- It's the doctrine of alternative and end result. You made unhealthy offerings and are actually paying the penalties. If you had constant the EGR valve proper whilst the investigate engine gentle got here on, you do not need had the tickets. Cost of an EGR valve is beautiful small. But you selected now not to try this. When the plate ran out, you knew it was once out, and made the alternative to hold riding. When you obtained the primary price ticket you might have stopped then, and constant the vehicle and obtained present so there could be no MORE tickets. Again you made a alternative now not to try this, and hold riding, and get extra tickets. How lengthy could it have taken for you, or your husband, to make a sensible mobilephone name to the courts and give an explanation for your clinical situation? The courts could have gladly given you an extension to your look. But once more you made a alternative to disregard it till there was once a warrant on your arrest. Even now you've gotten made a alternative to invite a number of strangers at the Internet as an alternative than name the courtroom approach or authorized help to discover your choices. So, welcome to the exclusive global of penalties. Good Luck.

- i've got had this very comparable concern 4 yrs. in the past, which grew to become into actual got here across 20 yrs in the past. If the back pass of blood in the mitral valve is extreme and the midsection starts off to amplify, then the only ingredient which would be performed is a valve replace, which i did and stay an exceedingly regular existence now. look ahead to fatigue, dizziness and shortness of breath. If those issues ensue frequently, make an appointment along with her heart expert at modern.
