Ball Valve For Heating Supply

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.

                                             

Design Features  of Ball valve for heating supply:

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:My 3rd valve keeps getting stuck when i play it, i have valve oil, but its just not working, help please
There are several possibilities. You may have buildup on either the valve or the casing. Cleaning it thoroughly should normally remove it, but every once in a Blue Moon it pays to take it in and have it professionally cleaned. They can inspect it at the same time and tell you if you have a bend or a ding in the casing. Sometimes they are really hard to spot, especially if they are hidden in one of the crevices of the detail work. A really good repair person can stick a scope down there and tell you if you have some kind of blockage in just a few minutes. The only way to really clean inside the casing yourself is to get a good bottle brush that fits inside with just a little bit of resistance. You should really get someone to show you how to do it the first time because you don't want to go scraping up the insides. There is one other possibility that is kind of rare. Sometimes you get some gunk up under the valve button and it sticks when you push it down. You should normally be able to see this just by looking underneath however. Best of luck and I hope you find your sticking point and are able to set it free.
Q:used in pipe line
I assume you are referring to a pressure safety valve (PSV) or a pressure relief valve. If you have a PSV connected on the exhaust side to a relief header that can have a pressure build up in then you can use a bellows type PSV to assure that the set pressure of the PSV is not changed by any pressure build up in the header You can get a better idea of this from the first link below.
Q:Where can I get a trigger valve like a one you use on a propane tank.
Its okorder
Q:what are the symptoms of bad egr valve??? My car is shaking on idle.. Tune up with all has already been done.
FIrst, locate remove and clean out your IDLE AIR CONTROL VALVE. This is the usual culprit. The EGR valve usually only need to be cleaned, as it gets clogged up with carbon. On may cars, I just disconnect them because they make the inside of the engine dirty. Using more modern spark plugs can lower emissions all by themselves. You can sometimes jolt the EGR back into shape by tapping on it with a hammer. Use Gum-out spray to clean your intake manifold out. It might just clean the EGR, too!
Q:Does anyone out there have any tech info or schematics for state of the art camless engines that run pneumatic valve train?
not really
Q:This valve has flow indication embossed on their body.
the gate valve is a very important one in flow measurement and also used to help the measure of flow. for example if you know the pneumatic comparator operation, you can easily under stand the gate valve. the gate valve is mainly used for to adjust the float in the tube to zero position or the clearance value.
Q:why do new motorcycles need to get their valves shimed alot? can someone explain how the whole valve adjusting thing works? why do some engine types require more attention? i have owned thumpers my whole life and never really thought about it. i was looking at this like cheap beater bike (hyosung gt250 v twin) and i read the valves need to be checked like 3 times in a short span, wtf??
Your prospective Hyosung may require some more frequent adjustments because the initial wear on its machined surfaces would still be polishing each other off.... surfaces like your hardened valve seats against the sealing surfaces of the valves... Or, the hardened surfaces of the cam lobes against the rocker arms. If your Hyosung's engine has been properly engineered, then its components have been properly case hardened. After their initial microscopic machined imperfections have been polished smooth, they shouldn't have to be checked as often. The Hyosung 250 was designed in Hamamatsu Japan by the same people who design Suzukis. It should turn out to be a great motorcycle. Perhaps frequent valve checks are because it's high revving and air cooled.?.? I owned an air cooled KZ550 Kawasaki, once. It required valve checks every 3000 miles. On the other hand, my wife has a 2007 Corolla. It has a low revving, Double Over Head Cam, 4 valve per cylinder LIQUID cooled engine. It requires valve adjustments every 60,000 miles.
Q:I don't have one single water shutoff valve in my house that will shut anything off completely. It looks fairly easy to repack them, and I have the tools, and there are instructions all over the internet. The question I have for the experienced among you is what packing material do I use? I have heard graphite thread and teflon tape and even joint compound.Is one better than the other? Easier to use?Also, if there are any pitfalls I should know about before I undertake this, please advise.Thanks in advance!
For stopping leeks use teflon tape to lub your valves use plumbers grease it s good idea to have a tube around not expencive
Q:I have adjusted the valve clearance twice, I still have a noise on the #2 cylinder intake. What might be causing this?
Assuming that you have adjusted the valve clearance properly, there are still a few other things that can cause valve noise: a) cam lobe wear as already mentioned, b) valve sleeve/guide wear c) wornout/necked valve stem d) wornout rocker arm (lobe or sleeve) e) wornout rocker arm shaft f) weak valve springs
Q:what's the function of a car valve???????????
Cylinder head valves come in many designs and combinations. Their may be two, three or four valves in the head and combustion chamber that open and to let air and fuel in while the piston compresses the mixture and is ignited near top dead center. When the piston is near bottom dead center the exhaust valves open where the piston pushes the spent gasses out underneath the open exhaust valve. As the piston nears the top of the exhaust stroke, the intake valve opens to allow the air/fuel to enter the combustion chamber and cylinder bore. As the piston sweeps down vacuum is created in the cylinder and more fuel / air enters. When the piston reaches the bottom of the intake stroke, the intake valve closes in preparation for the compression stroke. Go to the Wikipedia Encyclopedia ot How Stuff Works to see how a four stroke engine operates. You'll see what the valves look like and how they work.
