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.

Features and Applications
Raymond's fully welded ball valve for heating supplyand Fuel Gas systemare used to control the flow at fully open or closed position,not regulate the flow.Only special types of ball valves can realize the flow regulation.Therefore,our welded ball valves can satisfy the requirements of heating systems,e.g:
★Main pipelines of heating equipment
★Cross channels of heating pipes
★Heat exchanger station and any long distance operating station,e.g:
For the transmission of hot water and two kinds of mixed media(water,air or natural gas),limited to Max.4.0MPa and 200°C.
For the transmission of natural gas and one medium,from -30°C to 60°C,and even up to 150°C using specially designed ball valves.
★Coal gas pipelines,trunk and the branch supply lines.

- Q:the intake maniford tuning imt valve is stuck open how do i fix the problem
- It's a valve in the intake manifold that controls airflow depending on RPM, for maximizing volumetric efficiency at both high and low RPM. Many design parameters of any engine are chosen to maximize either low end torque, or high end horsepower, or most often, some sort of compromise between the two. The IMT Valve helps make it possible to design an engine where both are better than if it didn't have one. Variable valve timing operates on much the same principle, except this applies to the air passages in the Intake Manifold. How you fix it would depend on why it's stuck open. But I wouldn't count on a cleaning being able to fix it. More likely some sort of physical or electrical problem. Either way, chances are you'll need a new one.
- Q:My Dr placed me in the care of a cardiologist who ran some test and an echo scan reports i have a leaking valve but she failed to tell me which one and i failed to even think to ask. What are the results of leaking heart valves? I asked my mother and she says each one has a different result. What are they? Any help would be great. thanks.
- There are four valves in the human heart (Mitral valve, tricuspid valve, aortic valve and pulmonary valve). If the heart valve is leaky, the doctor can hear heart murmurs through the stethoscope. Leaky valve may cause bacterial endocarditis, heart palpitations or even heart attack. Medications will be administered for prolonged period to control the heart disease complications. Echocardiography report will clearly state which heart valve is leaking.
- Q:i have this valve and its really stiff i was wondering if there's a way to loosen it up a little its a KBI Ball Valve baught at Ace hardware and it looks like their might be a way of adjusting it i just dont know how
- tap it lightly with a hammer while turning it
- Q:where is the heater control valve on a 1996 volkswagen passat
- i'm no Ford fan, yet a Mondeo resources of a similar fee might want to be my determination. Neither Passat or A4 are fairly good, and service prices for VAG diesels are astronomical. once you're insistent on an A4 or a Passat, ?a million,00 is going to get you a finished smash till you're prepared to spend a lot of time being dissatisfied by utilising the final public of autos on the marketplace.
- Q:Last year an echo revealed severe aortic valve regurgitation with low ef of 37 but ecg was normal. i am 36 yrs old. I have noticed that i often have chest pain when i lie on my left (especially after a heavy drinking or if my bp is high) but the pain subsides when i lie on my right or back. Is it possible that my aortic valve only leaks when i lie on my left side, if so, can I continue living a normal life without needing valve replacement surgery if avoid lieing on my left side. or i'm i fooling myself, is the heart damage progressing silently?
- Hello, You don't tell us *why* your doctors think, you developed this problem with your aortic valve in the first place? Has there been any infection of the valve with germs, (bacterial endocarditis)? Did you have Rheumatic Fever as a child? Were you born, with stenosis or regurgitation of your aortic valve? Do you have abnormally early, clogging-up of your artery-linings with cholesterol?
- Q:And why is it so expensive?So after many months of trying to figure out why my 93 Mercury Cougar V6 has been breaking down chronically, I was recently told it needed a valve job. At 21 years old and just over 83k, l suppose that's the big issue.What exactly is replaced/fixed with a valve job? Will my car run like new AND STAY THAT WAY? Thanks :)
- The valves (located in the cylinder head) allows fuel/air into the cylinder and burned exhaust gases out. Valve jobs can be expensive if they have to replace the valves, and/or valve guides, valve seals, valve seats, valve springs, etc. A car with 83k miles should not need a valve job unless is was very poorly maintained. I think your mechanic is looking for some money from you. Although it's possible that one or more of those items you've listed had failed, I've NEVER had to replace a single one of those items in ANY car I've ever owned. All of my cars have lasted over 200k miles and not once have I had to replace any of those items. I've been driving for over 48 years. Find another mechanic before you go broke.
- Q:Is there anyway, from home, that I could rule out a bad heart valve as the cause for my heart palpitations and arythmia?
- NO THERE IS NO WAY TO TELL IF YOU HAVE VAVLE TROUBLE ONLY SPECIAL TESTS LIKE A ECHOEKG OR A CATH
- Q:I have a 2000 Ford Explorer sport(2wd). I live in the Fort worth,Tx area. What would be a resonable price to have this valve changed out with a new one(valve labor)?
- The okorder . To replace this part yourself takes all of 1 minute, and should be self-evident once you see the part. To erase the code, you only need to disconnect the battery for a few seconds. Hope this helps.
- Q:non-return valves
- ..?..non-return valves..? I will assume that your 'non-return valves', are what is also known as check valves. Check valves allows flow in one direction only. These are used wherever you need to prevent backflow into the system, or to maintain a charged circuit with fluid, until you choose to unload(depressurize ) it. Now, why are they used in discharged lines of salt water, basically to prevent backflow....reason not known, here , requires usage info.
- Q:the pressure relief valve on the top of the tank needs replaced
- Gas fired? Place thermostat to pilot to keep burner from coming on while you work. Turn off cold water supply to Hot Water heater. Open all the Hot water faucets in the house. Get a Pipe wrench and some pipe dope. and of course the new relief valve, place some towels under the relief valve as some water will leak out. Put pipe dope on the new relief valve threads, remove old relief valve using steady pressure, immediately put in new properly pipe doped relief valve, screw in hand tight, then use pipe wrench until it is set. Don't over tighten. Dry off area around new valve so you can more easily detect leaks. Reopen supply water to HW heater, let faucets run until no more air comes out, then shut faucets. Put regulator back on. Done.
