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:What is a valve mismatch in cars. code 300, 302, 420. All togather. Mechanic is telling the truth to do tune up and all. Is iT valve itsef? What is a (bad) coild? MITSUBISHI MIRAGE 2000
- Wherever you are get out. You are about to be ripped off. This will probably be too late. I gather the code you gave is the trouble code, as they are called, from the cars obd. The code 300 is random / multiple cylinder misfire. The code 302 is cylinder # 2 misfire The code 420 is catalytic system below threshold bank # 1 Deciphered this means you have a spark plug misfiring in cylinder #2, bank # 1. The misfire is causing a rich gas mixture in the exhaust system that is detected by the sensor and therefore it says you have a catalytic converter problem. I would suggest you replace your spark plugs, if they have a lot of miles on them. Are they the original plugs ? I f so they are probably due. Get out of there and go find an honest shop that will not rip you off. Now that you know the problem they can;t cheat. I don't know what all that other valve business was about but all you have is a misfiring spark plug.
- Q:need a different pump for? Is this some improvement on the old valve?
- There are schrader valves which are bigger diameter and are used also for automotive tires. They have a spring-loaded center pin that gets pushed down and opened when a inflating head is used. The spring is what keeps the air in the tube. The presta valve is the skinnier one. It does not rely on a spring to keep the valve close. The air pressure inside the tube keeps the valve closed. Generally, less expensive bikes use schraders while better bikes use prestas. All decent pumps have pump heads that accomodate both types. Either it is done by manually reversing the inside of the head assembly to change between presta and schrader or the head automatically adjusts or you use the appropriate one when the head has holes for both.
- Q:I had to replace the seat washers/stems etc in order for the constant drips from the kitchen faucet to stop. It did; but when i went under the sink to turn the water valves back on, the hot water valve felt as something inside it went smooth??? i can turn the hot water valve left and right but nothing is happening. No hot water at all from the kitchen faucet..Also there's low water pressure from the cold water that only came about when I tried to turn the hot water back on from the valve underneath the sink
- Unfortunately most valves used today are made of plastic that only look like metal on the outside. Sounds to me like you and I live in the same house. I have to replace four different shut off valves because they are stripped. I am working on the kitchen one right now. Stripped Valve with no cold water and very little pressure in the other valve. If you ever have one replaced by a plumber, insist on all metal valves. I will physically inspect them from now on before they replace them. Once stripped nothing you can do but put a new one on.

- Does not apply to 4 stroke motors.
- Q:1990 Pontiac Sunbird 2.0L Fuel Injected has EGR Valve, I can suck and blow through the hose connected to it, an I supposed to be able to do this, or not...? It looks old, like it's been on the car forever...
- It recirculates the fumes and the air--but a cracked hose is a nightmare if vacuum leak develops--fix it--just get a new hose and happy motoring
- Q:Hi. I am planning to install new kitchen faucet and noticed that there are two shut off valves under the sink. One of them is badly rusted and needs to be replaced. I noticed that it is connected to three pipes (one of which is kitchen faucet). The other is clearly water coming in. What is the third one connected to wall? Also how should I go about replacing this? Anything that I should be careful of?
- it looks like a 1/2 inch galvanized pipe out of the wall, and the valve is screwed on to it. kinda hard to see the back side of the valve and pipe. it could be a 1/2 inch copper pipe and the valve could be a compression type. anyway, you will have to cut the water off unless this is the hot line in and if so you can cut the water off at the water heater. its probably a cold line in and obviously you cant take the valve off without cutting off the main supply line some where. take off the two small lines and don't move them around to much, they are compression fittings so just reattach them to the new valve. then unscrew the valve, you may have to hold the incoming pipe but just try the valve first. take the valve to a plumbing supply, Lowe's, or home depot and get one just like it. if one place doesn't have it go to another and find the same valve. if it screws on get a small tube of pipe dope to coat the threads. if you anticipate problems get a 1/2 inch galvanized cap [if that is the pipe you have coming out of the wall] so you can plug the pipe and cut the water back on temporally. this is general info so you will have to deal with your special situation. good luck.
- Q:i believe it's to do something to the valve guide to make it the right clearance n not go straight to the valve seat right? or is valve seat next?
- Once the valve guide is installed, it has to be reamed to fit the valve stem. After it has been reamed to fit the valve stem, the new valve needs to be seated in. (The valve seat should have already been done by this point) This can be done with a machine tool, or it can be ground in by hand with valve grinding compound. Once this is accomplished, the valve is removed, everything is cleaned thoroughly, and the valve is reinstalled with the spring and keeper. Normally you would do all the operations to all the valves at the same time. (That is, you don't grind in one valve, then go back and ream another valve stem. You do all the operations required at one time. So you would install all the valve guides, then ream them all, then grind or face the valve seats, then check the valve contact area, then remove all the valves, clean the head and valves up, and then reasemble into a completed head unit.)
- Q:My mother is 40 and is going in on the 21st for an aeortioc valve replacement. We are so stress on deciding between what type of valve she should have to get. please help. please include things like costs and medicines and anything else that will give us more info.
- I okorder /... okorder and I will answer from my personal experience. The only difference in her surgery and mine is that they are replacing her aortic valve and I had my mitral valve replaced. Oh, I forgot to add about costs, depends upon State you live in. Here in NC my surgery in 2003 was about $60,000 to $70,000 (but I did have insurance and I only ended up having to pay $2,500. I was in the hospital for 9 days also.
- Q:Carbon keeps building up in the EGR valve. WHY?? and HOW DO I PREVENT IT? The engine is in PERFECT shape otherwise.
- I have one too. I replaced the catalytic converter and still happened. I found out that when the EGR is replaced, you should also replace the fuel distributor. It is also under the intack manafold. Not the ingniton distributor. After that, it never happend again.
