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 am replacing my vanity sink with a Pedestal sink. I turned the shut off vales to the off position tight.I disconnected the cold water and drained the remaining water and everything was fine. I disconnected the hot and drained the water from the connecting tube but water still came out of the shut off valve at a decent pace.I placed my finger over the valve and i felt pressure build up...like when you stick your finger over a bottle of soda.I tightened the bolt on the valve and even the screw to the handle to no resolve.any ideas on how to make it stop while i connect the Pedestal sink?also, i am as novice as it gets.thanks in advance
- Your relief valve will could desire to be for tension and temperature! while water is heated it expands. a variety tank is often needed. a common significant subject and frequently neglected is a verify valve on the chilly water inlet into the water heater. besides the fact that if it particularly is in a blending valve very probably fastened or some water warmers have been given right here with warmth traps fastened on the heater. the warmth temperature capture on the chilly water inlet had a plastic marble that floated up and sealed heat to your water heater. in many situations they seal tight and did no longer permit the water out because of the fact it speeded up. in the adventure that your 2d relief valve is leaking you often have some element like this happening. a kind tank put in on the scorching water area will scientific care this. You mentioned you have became the warmth temperature all the way all the way down to ninety. have you ever used a thermometer to verify the water is in the ninety degree variety? think approximately a foul thermostat on the water heater it is over heating the water, in spite of the actuality that it is uncommon.
- Q: what does mild sclerosis of aortic valve means? Why does it happens and what is its curethanks
- This is a routine, well established procedure. The incidence of major complications are less than 4%. There are two kinds of artificial Heart Valves. One is mechanical, and the other is tissue valve. The mechanical valve requires the person to be on life long anti-coagulation therapy. This also requires periodic check on the persons pro thrombin time. Based on this, the anti-coaglation dose will be adjusted. The problem with anti-coagulation is that it may lead to bleeding complications. The tissue valve is made from the tissues of a bovine or porcine heart. The tissue is denatured to ensure that the valve is not rejected as a foreign tissue. (This is not a problem with mechanical valves.) Being made of tissue, these valves do not allow clots to form, which means that anti-coagulation after a short initial period is not required. This is a major advantage, especially for women, who may have some earlier bleeding problems. Then why are mechanical valves used at all? Being made from non-living denatured tissue, tissue valves cannot repair themselves. They also tend to get calcified in younger people with more calcium activity. They also have a shorter life than mechanical valves. Surgeons tend to favour mechanical valves for younger people (whose life expectancy is higher), and the tissue valve for the older, as such people may already have some bleeding problems, the valve's durability is not critical and the patient has lower calcium activity. These are general considerations. Only a surgeon armed with the full test results, and a knowledge of the patient history, who can advise the patient on what is the best option in each case. To reiterate, AVR (Aortic Valve Replacement, not my initials) is a routine procedure and recovery tends to be uneventful. Wish you all the best, and as uneventful a recovery as possible.
- Q: Which is worse ? And what causes it? I was told I had mitro valve prolapse but I m symptoms had worsen and so I saw a cardiologist again today and they said I have mitro valve regeritation.
- Firstly both conditions are not necessarily serious. Prolapse is the phenomenon of one or both mitral leafets bending slightly into the left atrium when the heart contracts. Normally when the leaflets close they dont clise straight but form a slight tent shape facing towards the LV. With prolapse the leaflet bends beyond the imaginary straight line of the valve annulus. Regurgitation is simply back flow through a valve when closed - all valves function as one way check valves to ensure one way flow through the heart. Its completely normal to have a small amouny of regurgitation at all valves except the aortic valve. Mitral regurgitation typically worsens with prolapse because the valve isnt closing properly. Usually prolapse and mitral regurgitation are not all that serious and only require periodic monitoring. Consult your DR if you suddenly develoop symptoms like chest pain or breathlessness. These can indicate the valve is degenerating further and may require medical treatment.
- Q: Hi i have a 00 bmw 320d and am trying to find out information on puting a dump valve in, is it possible?, what type of dump valve? and how hard it would be to put in?? any help would be much appreciated.....Thanks!!
- Most diesels do not have throttle valves (including yours), therefore a blow off valve would never work. They work by relieving the pressure build up caused when the throttle valve is closed (foot lifted off gas pedal in a petrol engine), which happens when you shift (usually only for manuals) so the built up pressure does not bring the turbo speed down. A side effect of this pressure being dumped is the whoosh sound, which some people desire more than the performance gains it offers. That sound is the air rushing out of the intake system, which usually has been metered already, and now is wasted. The ECU measures that air and adds fuel for it. When it gets blown to atmosphere, the fuel is added, but not the air. Now the engine is running rich. There are some systems that recirc that air back to the turbo, but then there is no whoosh sound. Anyway, since most diesels do not even have a throttle valve, it won't do any good.
- Q: Since the valve drain is usually open, I am wondering if placing the cap on the drain has made my water heater dangerous.
- If it is the drain valve and not the pressure relief valve, you should be fine. The drain valve is not usually open, just when the sediment is drained out of the heater or when it is drained.
- Q: Can a dirty or faulty EGR valve cause overheating. My 2001 PT Cruiser is overheating but only on very hot days and when the air conditioning is on. Back flushed and pressure tested the radiator, changed the thermometer, fluid was low but doesn't seem to be loosing fluid since refilled. Check engine light came on and indicated poor air flow through the EGR valve. Is it worth replacing prior to pulling the radiator to check that for the problem with overheating? Mechanic I trust doesn't think the EGR can cause overheating.
- This people above do not know much about EGR's which one of the main purposes is to lower combustion temperatures by introducing exhaust fumes into the intake. So yes it can add to the overheating problem. source GM tech
- Q: Okay I know lots of people wonder what is better presta or schrader...well I realy don't. My bike was made for presta and thats what I have a question about. So I just got my bike back after is being stored away for a few years, so yeah it was neglected. Question is now that I am doing a tuneup on it I found out the valve came out of the tube. I don't know if that is normal and if I am able to put it back in. It looks like there made for the valve not to come out but I just want to make sure before I go out and buy a new tube. Hope you can help. Thanks. -Sarge
- First off, there is no question that presta valves are better! The larger a hole drilled through a rim, the lower its strength. Thus, all other things being equal, a rim drilled for a presta valve will be stronger than a rim drilled for a schrader valve. Tubes with presta valves are slightly easier to pump with a mini-pump than a schrader valve. Finally, they are a bit lighter than a Schrader valve. Secondly, you need to buy a new tube. There is utterly no hope for a repair if the valve comes out. Hope this helps.
- Q: My baritone is somewhat new, the first valve isn't going down, I've tried nearly everything and I want to avoid taking school instrument to a music store to repair.
- I have played for over 30 years and have a few to many horns. But I love to play. Sounds like its time for a bath. Take your horn to the bath tub. Fill the tub with warm water and a little DAWN dish soap. Lisen to me and buy DAWN, not something else. Palmolive tasts nasty, and the others do not cut the grease on the horn. Gently take out the valves and all slides. Lay them on an old towel. Lay the horn in the tub on an old towel so you dont scratch the tub. Let it soak. While the body soaks. Wash the valves. The valve might unscrew off the top stem. This would be great because you do not want to get the felt or corks wet. Be very gentle and careful, use an old white sock to scrub the old oil off the valve. Now that the valves are washed, rinse the valves with clean water. Now, take the old white sock that you just used and twist it. Then you can feed this into the valve case on your horn. Pull it through each of the three valves a few times. If you are realy good to your horn, you may even buy a snake made for cleaning trombones and baritones and run it through every pipe on the horn. Now rinse and dry everything. There should be no oil or grease left on the horn or the slides. If you find any go back and wash it off. First grease up the slides with slide grease or lanolin. Then oil (not grease) the valves with a good quality valve oil such as Blue Juice, Holton or Al Cass. Use just a few drops of oil on each valve. You place 2 (Two) drops on at a time and gently slide the valve into the horn. Spin and with any luck it will play like a dream. Now, you need to stop eating before you play. And never oil the valves through the hole in the bottom, that is where all the dirt is going. If you must, oil through the leadpipe. I remove the valves after I play and oil them. They are always ready to play this way.
- Q: my check engine light tells me that i need an egr valve, if i install one will that cut the light off????
- depends if nothing else with the emission system is messed up
- Q: can you put a blow off valve on a chevy cobalt ss supercharged?
- the correct answer is yes and depending on the size it may be critical. turbos use a waste gate while blowersaka super chargers need a blow off vale to prevent to much pressure in the cylinders. causing a blown head gasket, blown intake gaskets, or even blowing the blower off the top of the engine. If you ever look at a car that is set up with a real blower on the back of the intake manifold there will be a plate held in place by two springs, that is the blow off valve.
