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: Hi. I replaced my PCV valve but the hose it connects to is cracked at the end. It's still loose and I can pull it off with my hand. It is very hard to get it to stay connected. So my question is that while I am driving, what would happen if the PCV valve accidently disconnects from the hose? Would I still be able to get to a service center?
- in the short term, use a plastic wire tie to secure the hose until you can buy a new hose....you need to replace the hose.
- Q: Where is the Auxiliary Air Valve on my 98 Civic?I have a 98 Honda Civic ex and need to change the Auxiliary Air Valve
- you don't have on the Civic. The Auxillary Air Valve is a part of the AIR (Air Injection Reaction) system used to control emissions on domestic vehicles. Honda doesn't use that part nor that system. there was another 'auxillary air valve' used in old Bosch fuel injection systems that added air when the car was in cold start enrichment. that part hasn't been used in the last 20 years by any manufacturer. The control of the idle at cold start is done by the idle air control valve. The idle air control valve located under the thottle body on most hondas; some models have it on the side. there are usually two vacuum hoses and one electrical connector to the valve. that valve controls the engine idle and when bad it would cause the engine to surge at idle. if that's not the case, then we need more information on what you are trying to fix and what you mean by auxillary air valve. if there is a diagnostic trouble code associated with it then that would help. hope that helps
- 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: If my understanding is correct, in a standard combustion engine as you press the gas pedal the speed of everything increases: the cam shafts spin faster (and thus the valves move faster), the pistons move faster...EVERYTHING goes faster. That sounds like an optimal system in theory, so what is the benefit of having the valves be able to be intelligently out of phase (for lack of a better phrase) with the rest of the system?
- Valve timing is a compromise. You can optimize valve timing for a certain RPM, but it will be wrong for every other rpm. Advancing a cam helps bottom end, and retarding a cam helps top end. Actually changing duration and lift is more difficult, but can be done, and IS being done. The benefit is to widen the torque curve, helping both power and economy
- Q: my dad is going to go under heart valve replacement what are the chances of him surviving he is 58 years old and has copd
- It depends a lot on which valve and why it's being replaced, but unless the COPD is very bad, the average chance that a 58yo man who does not have any other major medical problems will survive single-valve replacement surgery is better than 98% if the surgery is done by an experienced surgeon at a good hospital. The COPD will very likely mean that his post-operative recovery will be prolonged and difficult, but he should do fine.
- Q: How do you repack an osy valve? Where do you get the packing from? Do you have to shut down the water to do it?
- For most valves, replacing the packing can be done without shutting down the water system. The first step is to back seat the valve. Back seating will occur when the valve is fully opened, and will temporarily seal the leak around the stem. You simply open the valve completely with about 50-100ft-lb of pressure. Once the leaking has stopped, you can remove the packing bolts and nuts on the packing gland. Slide the packing gland up the stem and you will have access to the packing. You may need a packing hook, which is a flexible corkscrew tool, to help remove the old packing. Once you have removed the old packing you will want to repack the valve with new packing by wrapping it around the stem and pushing it down into the valve body. After the new packing has been replaced, it may need to be compressed a little so that the packing gland can be reinstalled. This can be done using two pieces of all-thread rod. Cut both all-thread rods to 6 inches long, making sure to use the same diameter all-thread rod as your packing bolts. Place the all-thread rod through the packing gland and tighten the nuts onto the all-thread rod to compact the packing in the valve. Next, remove the all-thread rod and replace with the bolts. Turn the hand wheel, so the valve is about half way open. Finally, tighten the nuts evenly until all leakage around the stem stops. You may need to exercise the valve a few times to make sure there are no leaks around the stem. Be careful not to over tighten the gland because it can crack and there is no reason to compress the packing more than is needed to stop the leak.
- Q: Also what prevents this from occuring? I have a lab due tomorrow for my biology class this is one of the questions. the answer is no where in my book, and we haven't discussed this in class. im also having a hard time finding the answer online. i would assume it would have something to do with the elasticity of the valves, and i know that when valves are weak sometimes blood can flow back into the artium when the ventricle contracts causing a heart murmur and other problems, but i haven't came across any information that talks about the valve being pushed backwards. if you can help me out that would be awesome! thanks =]
- the heart valves maintain the unidirectional flow of blood in the heart by opening and closing depending on the difference in pressure on each side. (wiki) So I would assume that the pressure of blood flow is what prevents the valve from pushing backwards. ALSO Atrioventricular valves These are small valves that prevent backflow from the ventricles into the atrium during systole. They are anchored to the wall of the ventricle by chordae tendineae, which prevent the valve from inverting. The chordae tendineae are attached to papillary muscles that cause tension to better hold the valve. Together, the papillary muscles and the chordae tendineae are known as the subvalvular apparatus. The function of the subvalvular apparatus is to keep the valves from prolapsing into the atria when they close. The subvalvular apparatus have no effect on the opening and closure of the valves, however. This is caused entirely by the pressure gradient across the valve.
- Q: I had some great answers to my question yesterday... I have decided to have the valve job done... Since I have decide to go this route... I need some reassurance, the few people I have suggessed this option to have now told me that typically after a valve job other problems will start showing up. They have said that the car isn't worth putting money into and to get ride of it.
- Getting a vlave job done isnt going to hurt your car at all, nor your motor. Make sure you have a reputable machine shop do this (most garages dont have the tools for it). If a 3 angle valve job is done correctly and new valve stem seals, retainers, and spring are all carefully installed to manufacturer spec then there should be no problem at all. Many shops will do a sloppy job grinding the valve face (which is a hard thing to get the knack for) and will install to valves without another thought. When new valves or old valves with resurfaced faces are installed the spring rate of the valve springs needs to be checked to ensure are srpings are the same strength. Also once installed, the height of each installed valve/spring needs to be checked to make sure its in the specified allowance. If valve seats and surfaces are all done correctly along with a profesional installation I wouldn't worry!
- Q: 1998 camaro3.8L v6sometimes when i start the car, it makes this loud ticking noise that goes with the RPMIm pretty sure its the valve, anyone know how to fix it, and how much it might cost?
- Stuck Valve
- Q: i have an old 79 malibu and its only got a 267 in it. I wouldnt buy new valve covers because its not worth it to me but i was thinking i could clean the ones i got up a little bit. i was thinking of painting them. What kind of paint should i use? and one other thing is the gaskets. I figure while i have them pulled off i should put new gaskets on. I read up about getting all the old stuff off but i was curious still about it. I was just looking at some average ones made of cork for 10 bucks. Do i lay the sealer downthen put the gasket on , then put the valve cover on?
- just paint the valve covers ..high temp heat resistant paint... don't go with the cork gaskets ...use permetex silicone 3 bucks a tube and easier to work with
