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: What is the International Standard or other acceptable calculation or table for determine the air supply of pneumatic actuator in shutdown valve 6 to 24.Desired answer will be air flow in SCFM.Thank you.
- Shut down valves I've worked with haven't had an 'Air Flow' for their operation. For the smaller valves, they consist of diaphragm operated valves either held open or closed by pneumatic pressure. The air supply at 25psi to give a diaphragm holding pressure of 15 psi, is via a solenoid valve which dumps the air pressure to either open or close the valve depending upon its function. (That of isolating a system or relieving pressure). The solenoid is actuated by a signal from the shut-down system, and the valve is a 3-way unit which isolates the supply air and vents the pressure off the diaphragm. Other SDV's in my experience, are operated in a similar way but are much larger and are operated by a pneumatic air cylinder and piston with air supplied at 100 psi. Others encountered are ... MOV's...Motor Operated Valves that can be automatically operated from the shutdown system, or Operated Remotely from a safe distance (ROV's).
- Q: Why are pig hearts valves used as replacements for damaged heart valves in humans? Are there any complications and are they still used today?
- Biological valve is made of human or animal tissue. These valves last 12 - 15 years, but you may not need to take blood thinners for life. Human body has a tendency to reject foreign material such as porcine valve. Medication can be used to retard this effect, but is not always successful. Biologic porcine heterograft - harvested aortic valve of pig that is preserved in glutaraldehyde and mounted on specially designed sewing ring. (Carpentier - Edwards/ Hancock/ Medtronic) Tissue valves are also made from 16 to 18 months old calves and harvested aortic valve from human cadaver.
- Q: I got a 318 V8.. I cant seem to locate the valve cover to replace... but I did notice that some of the replacement gaskets/filters are from the 91-93 dodge ramcharger.. Is it possible for an newer model to fit exactly on my 1989? are all dodge 318 the same size?
- You obviously just suck at anything to do with cars and should go neck your self asap

- Q: I need a bit of help. I am trying to find the location of the EGR Valve on a 1992 Chevy Cavalier 2.2L. If anyone can help me out by posting back a picture or diagram that would be great. I found all the text directions, but did not find that to be helpful.Thanks,
- Ok here we go First raise the hood the engine sits side ways. now on the Passenger side of the Engine compartment is the engine. (i'm serious here) the end with the belt and the pulleys wil /and is Called the front even thou it sits sideways. now the thing on top of the engine is called a valve cover start looking from the front and follow it to the back (that's toward the Drivers side) when you get to the end of the valve cover look down you will see a Valve about 2 inches below the valve cover it has a black Vacuam line that runs to it this is the EGR valve. now Why in the world do you want to make it open on a 1992 Cavalier. most of the time we replaced them because they stuck open and caused idle problems. if your trying to just keep the light out Good luck
- Q: We just got a new washer and cannot remove the old hoses from the pipes with the shut off valves on them. I don't want to bend or break anything. any suggestions?
- Renpen is correct, but after squirting some WD-40, I would tap it all over with a 7/8 box end wrench ( a big one) and that way loosten the crud that is keeping it from unscrewing and replace them with stainless, flexible hoses.
- Q: I Have a 2001 Honda Accord 3.0 V6. Would a clogged EGR valve cause it to run rough and have problems starting up when it is warm? It also runs hot. I have replaced the thermostat and the cooling fan relay? What could cause all of this? PLEASE HELP!

- Q: need a different pump for? Is this some improvement on the old valve?
- Dita is correct. You do not need a new pump. Most of the new ones (ones you'd find at a bike shop, probably not Wal Mart pumps), will handle both. The newest ones have a smart head where you just plug in the valve, flip the lever, and the pump figures out which valve stem you have. On slightly older pumps, it is a matter of switching the pump head internals around. On the really old pumps (or really cheap ones), you need a brass or alloy adapter that threads onto the presta valve and converts it to schrader.The schrader valve uses a spring to close the valve to prevent air loss. Presta uses the air pressure itself to seal the valve.
- Q: i know its going to drop some oil, im just wondering to what extent? how much oil is going to spill out?
- If your asking if the Valve cover will be full of oil..... No it runs back into the oil pan. There will be oil residue inside and it might drip a tiny bit when you remove the cover but.....
- Q: How do you know if you need a new EGR valve or if you just need to clean it?
- You obviously had a parts store diagnosis so maybe you should ask the person that put the idea in your head that the EGR was a problem for the answer. Did you know that an EGR code can be caused by numerous other problems.
