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:Whats the difference between Steam and VALVe?
I don't understand this question fully, but I think you like my answer: Steam is a software for gaming articles, but it also meaning gas on another word. Valve (www.google.rs/search?q=Valvehl=srclient=firefox-ahs=SCurls=org.mozilla:en-US:officialprmd=imvnssource=lnmstbm=ischei=8zHfTr2iIsKnhAeTy-yVBQsa=Xoi=mode_linkct=modecd=2ved=0CCgQ_AUoAQbiw=800bih=393) is a legal company, same as meaning the link I put there. Hope it helps! :)
Q:Leaky Toilet shutoff valve....?
as for the actual leak replace the supply tube to the toilet (it's called a closet supply tube)and don't get the braided one with the rubber gaskets already made into it i've repaired thousands of dollars of damage caused by them.get the poly supply tube,toilet supply nut, 3/8 compression nut and 3/8 teflon ferrule.(ferrule goes tapered end into valve)if the valve has to be replaced it depends on what type of water lines your house is plumbed with to determine difficulty of replacement.try a new washer---turn off water to house and drain best as possible.open toilet supply valve all the way and remove stem by unscrewing packing nut (the one the valve stem comes out of)you have to turn handle and packing nut to completely unthread it.replace washer and re-assemble. good luck.(p.s. hold valve still with opposing wrench or pliers so as not to twist pipe in wall or floor.
Q:1995 Intrepid keeps burning EGR Valves?
are you sure its the egr valves going bad or not the egr solenoids causing you to get the code,that will make it appear that an egr has gone bad when it really hasn't,good luck.
Q:Cylinder heads and Exhaust valves?
To answer your first question only, the benefits of changing cylinder heads and valves would be to improve the overall performance of the engine, like increasing its horse power, speed and fuel consumption. To prove to the vessels owner that this needs to be done, a compression test should be done on each cylinder by a mechanic. This will show how each cylinder is functioning, and the results need to be cross referenced with the compression specifications for that specific engine.
Q:what does the btu rating mean on a temp and pressure valve?
You can absolutely use one with a higher btu rating., but not with a higher pressure rating. Just be aware that this valve has a much lower blowoff point than a typical hot water heater tp valve, so be very sure of the PRESSURE rating on the new valve. (should be 30 psi, just like the old one) You may want to check to be sure that your expansion tank isn't water logged, and that your boiler pressure isn't too high.(shouldn't be much more than 15psi or so, unless you have a multi story house). Expansion tank or water feeder pressure regulating valve may be having issues,....sometimes there's a reason why the tp valves leak. Hope this helps
Q:Control valves?
Hope this helps in some way... To start the 3 main flow characteristics of a control valve are Liner, Equal percentage and Quick opening (or fast opening). If you interested there are also other characteristics. As far as i am aware the lead time is the time in which a signal is sent to the valve and the lag time is the time in which the actuator moves and closes the valve. The pysical movement. As for your final question the only thing i can think of is to alter the actual size of the butterfly valve or put a reducer before it. Sorry if my information was of little use.
Q:1.positive valve rotator help burn exhaust valves? 2.valve rotator are used on in intake valve? T or F?
Valve rotators are just that, they cause the valves to rotate during operation preventing wear in only one spot there by extending the life of the valve and the valve seats.
Q:Function of reed valves?
GuardrailJim and Badobses---, you both got it almost right. You other guys, take a lesson. First, Jim Bad should have said fuel is pulled into the crankcase, through the reed valves. The crankcase is a small sealed off area on a two stroke, just larger than the flywheels. Old days, the piston skirt was used for a valve, opened when the piston was on the way up, closed on the way down. Both systems use the piston skirt to open and close the exhaust port, which opens when the piston is on the way down on the power stroke, normally about half way, give or take a bit. Intake, into the combustion chamber starts when the transfer ports open, which is a bit after the exhaust port opens, and closes just a bit after the exhaust closes. With the reed valve, mixture is pulled into the crankcase at any time the case pressure goes below atmospheric. Also stops, by the reed valve, as soon as pressure goes over atmospheric. This lets the engine induce a fair amount more mixture than was possible with a piston port, and no blow back of mixture through the carb. This is a simplification of a very complicated piece of air flow. One will know chap I know, who also built some of the best, if not the best 2 stroke exhaust went back to college, got a Doctrate on accoustics before starting design of his expansion chamber systems, and THEY WORKED! Sorry, I did not mention disk valve engines the first time, in effect kin to the piston port, except they are timed for opening and closing to be at proper time to get maximum flow into the crankcase. Less blow back than with a piston port. Between piston port and reed in power, all else equal. Reed valves are all-round best. Cheers, Tomcotexas.
Q:valve cover question?
If the car gets to sit for several hours that should not be a problem. Otherwise give the other paint 72 hours to dry hard before removing the valve cover. You may have to rag it a bit. Use hi-heat paint on the covers.(follow directions on the can)
Q:How often should the check valve be replaced on the pump of an Aquarium?
a check valve is to prevent back siphoning of water into the pump if you have a power outage or unplug the pump by accident. I'd suggest checking it by blowing through it the wrong way; if air does pass through get a new check valve (check new ones to be sure they don't limit airflow too much, and that the close in the wrong direction, many are cheap crap and don't work the day you buy them, so check them before you leave the store with it...note: same with thermometers, compare them with each other so you don't get the one that's crap) what you want is a normal air valve, they come in various configurations, one or more valves so as to run multiple airstones and to balance the airflow to each stone or ornament. You should not however just use the valve to limit airflow, as this damages the pump eventually. You can just let one of two valves bleed off a little air; however make sure another check valve is in the line from the tank to the valves or else you risk water coming out of that valve if it's lower than the tank water level.....You may want a smaller air pump or an adjustable one instead.
