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:ex: 4 stroke 16 valve engine
- The intake and exhaust valves in a four stroke engine are timed to allow air intake on the the intake stroke, both closed on the compression and power stroke and the exhaust valve open on the exhaust stroke. The valves on a two stroke engine are generally automatic reed type check valves that allow for an intake stroke and close for the compression and power stroke.
- Q:Hey I'm high rite now and i have a checkup for mitro-valve prolapse tomrow, i was wondering if they will take my blood and see THC in me....
- Mitral valve prolapse exams look more anatomically than physiologically. Meaning, they will take a picture of your heart instead of looking at the chemicals in your blood. BUT a prolapse may mean that your blood does not have enough oxygen in it because your heart circulation is abnormal, they may take a blood sample to test the level of oxygenated blood relative to deoxygenated blood to check this.
- Q:When using seafoam through the PCV valve. Which side contains the vacuum? From the crank case of intake manifold? The brake booster line is very difficult to access and on their site it says I can apply seafoam through the pcv valve.
- The PCV valve scavenges OIL VAPORS from the crankcase tthe VALVE COVER. Remove it and you will FEEL the vacuum when you put your thumb over it. It will POP the small pellet inside it. Foolow up with GUMOUT srpay and use BOTH to clean the THROTTLE BODY and the IDLE AIR CONTROL VALVE, the IAC is resonsible for mixing AIR with injecte4d fuel. A dirty IAC will RUIN mileage and clog up the converter. GOOD LUCK!!!
- Q:I have my head off now I need to change my valves how do I do it?
- What I would do is just take the heads to an automotive machine shop and have a valve job done on them. They will do everything, grind and resurface the head and valve seats. This is the smart way to DIY. Do what you can do well yourself and let those with the proper tools training and expertise do what they do best. You'll save money this way and get the best work done at the best price.
- Q:In one of the two bathrooms - that we rarely used - I recently found that shower has now only hot water running. The valve is Moen brand with a single knob. On turning this, I get no cold water, but just hot water. I removed the knob, and decided to maybe replace the cartidge, but could not make any headway, after removing the acrylic knob. First, do I need to remove the cartridge?If yes, how? Is it possible to remove it without removing the back-plate glued to the Tile walls? Will appreciate detailed instructions to remove or fix the valve?thanks
- Moen, as well as many other brands have a feature that is cald a pressure balancer, or scald guard. Long story short, its so you don't burn yourself or freeze when some one flushes a toilet or the washing machine kicks in. You need to change it. Take off the handle, this may require and allen wrench to go in the bottom part of the handle, and then remove the front cover plate. Then take off the screw in the center of the valve. Remove the tube on the valve.( This should be a tube with a square notch at the top)Then remove the clip holding the cartridge. It has enough sticking out the top for you to grab it and pull it up. (Make sure your water is off) Then pull the cartridge out. Got a good grip and PULL. It doesn't always come out easy. Then replace it with a new one, and put it back together. Tada!!! Now Moen offers a lifetime warranty of parts, so it shouldn't cost you more then elbow grease. Find a local plumbing supply warehouse and they will give you a new cartridge for free, although they may require you to bring the old one first. Home depot or Lowes will not they will charge you 35-45 bucks. Hope this helps. Good Luck!!!!!
- 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:Just wanted to know what the significance of the number of valves is?I know that theres valves for intake and exhaust if i'm correct.if there is four i'm guessing its 1 for air and 1 for fuel if its fuel injected. and 2 for exhaust?are there bikes with 3 valves or more than 4 valves and why?and a basic carburated 2 stroke just has an intake from the carb side and then an exhaust.please give me more info and let me know if i'm correct or not.
- As goobersmooch says, your guess regarding 4 valves is wrong. On a 4-valve engine (i.e. that means 4 valves per cyclinder) there are two exhaust and two inlet valves. I can't remember offhand if there are bikes with 3 valves, but there are definitely cars with 3 valves. They are usually one inlet, two exhaust, because the exhaust valves get hotter (having to deal with hot burned gases) and two valves give a better surface-to-volume ratio, thus aiding with keeping them cool. I'm fairly sure there are bikes with 5 valves per cylinder, but I'm danmed if I can remember what they are. Why? Same principle applies - more valves in a given space means a better area for the gases/vapours to flow over = more efficiency. But eventually the ol' cost/benefit ratio catches up. It's harder to make a valve train to open 5 valves than it is to make one to open 4,3, or 2. All engines have their intakes on the carburettor side, whether 2-stroke or 4. Or, more acurately, their carbs are on the intake side. 2-stroke valves, if they have any, are completely different to 4-stroke, and they are on the intake side only. A 2-stroke engine doesn't necessarily need to have valves.
- Q:Hello,I've not found a perfect fit using a solenoid valve for gravity fed irrigation system. Primarily because it requires a constant drain on the battery while the valve is open. Is there a motorized valve to fit the bill? One that momentarily requires electricity to open and close the valve at 12v DC or less to work in gravity fed system?
- should not be any issue finding on your plumbing features. do only not forget approximately to deactivate and cap the line coming from the front. it is basic to apply that line with the two between the valves finding on the place you chop back and cap it.
- Q:I've been diagnosed with mitral valve prolapse, my doctor just told me that i need to setup an appointment with the hospital to look at treatments for heart mitral valve prolapse-to possibly have a heart valve replaced. I am wondering if i should setup an appointment with mayo clinice in minnesota to get another opinion on that? I'm wondering if surgery is an only option available to me, i have been taking beta blockers that have been no help for the past 3-4 months. Thanks.
- at the start, you ought to talk on your typical practitioner. they might certainly answer your questions extra proper than all of us right here. yet, i can assist you be attentive to that your situation can certainly be very uncomplicated. I certainly have a kinfolk member with an identical ingredient and he leads an exceptionally frequent existence and could no longer desire a valve alternative. If he engages in very actual interest (alongside with taking part in soccer), he does get drained certainly, yet different than that, he's high-quality. In case they did no longer clarify it to you (it seems they weren't very informative) right here is going: Your mitral valve is nearly a sprint door that opens and closes on your heart. once you have a mitral vavle prolapse, what which ability is that as quickly as that valve swings close, it closes and definitely swings IN slightly too far. (Ever seen a swinging door? comparable thought) This reasons slightly a leak. it is a few thing which will ought to be checked each few years in the process your existence, to verify that it does not worsen. touch your typical practitioner and ask her or him those questions, just to be on the risk-free ingredient.
- Q:I have a 4 diameter column of water 10' tall (filled with water). I need to find a flush valve unit to fit into the bottom of it so that it will flush all of the water out of the column in 1 flush. Essentially this will act as a large toilet but it is for a design project at school. My concerns are that the flapper will close before the water is completely flushed out of the column. Is there any way I can make the flapper stay open thus flushing all the water in column out without holding the chain connecting the float to the flapper valve?
- Flapper valves are all about weight and pivot points and center of gravity. The air bubble inside the plug acts like a ping pong ball initially, holding the flapper open. When the water gets down to the level of the flapper, it tends to close too soon as you point out. But you can attach a smal plastic cup to the back of the flapper that fills with water and holds the flapper open when the water level is very low. You put a small hole in the bottom of the cup so that the water in the cup slowly drains out and finally the cg shifts and the flapper closes.
