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: I was told Wed. that I need to have my aortic valve replaced. I was wondering if anyone could share their experience with this surgery good or bad. I am meeting with the surgeon on the 26th, and am very nervous. Any tips and or suggestions appreciated. I'm a 39 year old female.Thanks in advance
- if you have a tissue valve you will not need to be on coumadin the blood thinner but will need to have surgery repeated later on in life. if you have a mechanical valve placed then you will need to be on coumadin and typically it takes about a week to get your blood theraputic, then you will need to probably need to have you blood drawn weekly a few times immediately after. then it tapers down to once a month checks generally. goofd luck to you.
- Q: My friend had heart surgery and it was pretty serious. She got a new heart. Days later they checked her and discovered that she bursted a heart valve. The doctors say it's one she can live without. That really concerns me. The valves connect directly to the heart. Please help.. Will she be ok if she doesn't get it replaced?
- Nit enough information.
- Q: Bought a 1986 GMC 350day 1 started up good - idle was rough - idle really too low, when brakes where applied, it would backfire. (day 2) Changed oil which was really dark - oil filter too... ghanged spark plugs and wires. % 10 improvement... Engine lack power and vibrates but no more backfire.day 4 Changed Cap and rotor - % 30 improvement - day 5 Got the manifold gasket replaced. Same condition but silent... day 6 Changed coil in cap ... Changed fuel filter % 60 improvement... The thing ran like new... Full power I started beliving again..Got full oil pressure 300 kpa - no valve noise Ran 30 minutes on highway.... Valves started making noise especially on driver's side... Engine lost lots of power, and vibrates a lot... doesnt heat up to much but oil pressure seems very low. (day 7) Start up the thing, and even when cold and choke on, oil pressure not as good as in the beginning. What went wrong
- Sound like a blown intake valve. Do a compression test and if you find a bad cylinder, do a leakdown test. A leakdown test is where you pump compressed air into the cylinder with the bad compression. You need to make sure that both valves are closed which is determined by the crank position. If the air is leaking into the intake/carburetor, then you have a bad exhaust valve. Time to pull the heads, or do an engine swap. As for the buy a Ford guy, the GM blocks are the best out there. That is why almost all marine engines are GM blocks.
- Q: I have a 2000 jeep grand cherokee v8 4.7L it has a stuck valve making knocking noises my question is can i still drive it !? or is too dangerous
- For 1 how do you know it has a stuck valve , if you know that you know how to get it unstuck (pb-blaster ) or something like that , or is it carbon holding it open if it is you will need to pull the head becouse the head of the valve will come off and damage the piston and the block , good luck.30 years exp on cars and big trucks
- Q: When i went to the cardiologist a few months ago, i remember him saying that my pulmonary and tricuspid valve were leaky, and i think he said they were a 1 on a scale of 1 to 4 which is minor and of no concern. but i have valve problems in my family and i got thining about it. anybody know what this scale is called/have more info or was it something he just made up to tell me that it was minor?

- Q: I got a cold air intake installed on my vehicle and don't have any AEM bypass valve installed, for preventing hydrolock. If I drill a small hole(e.g 1cm) on the intake(short ram section) can that prevent hydrolock or do I still have to get one of those bypass valves?I'm looking for any alternatives, instead of those AEM bypass valves and was wondering if drilling a small hole in the cold air intake could help in preventing hydrolock, just as good as the AEM bypass valve.
- Only version 1 of the AEM CAI's could even use the bypass valve. Version 2 will not work with this bypass. This bypass valve is pressure sensitive and set up to open if the air flow was blocked at the filter. It also has a foam filter on it to still give you some filtration of the air. You do not want to drill a hole in the intake. This will allow unfiltered air to enter your intake and reduce the efficiency of the intake system. I'm not sure what kind of car you have this system on, but on my Accord, the filter was moved down inside the front bumper just in front of the drivers tire. It is surrounded by plastic and has minimal chance of any water splashing in to it. The only way I can see water getting to it is if I were to try and drive in to a large Pool of water in which it would have to be higher than the floor of the car. Anyone who would even attempt such a thing would be a fool in the first place for trying to run through such high water. If you have the Version 1 AEM, get the bypass valve. Don't drill holes. If you have the Version 2 which can not use this valve, just don't try to use your car as a boat. You shouldn't have any problems. TGP
- Q: I own a 2wheel drive 2003 Hyundai Santa Fe 4cly. The engine light was on the code P0401 came up which is the EGR valve. I had it changed out the engine light came back on after I had made it almost home. I took it to auto zone same code came up that made me take to the shop for repair in the 1st place. Ugh. Please help! What's the problem???
- My vehicle is throwing a P0401 code. I was going to replace it, but instead I am going to clean it and replace it. I know the mechanic will want to replace it and charge me well over $100 (I'm seeing the part go for around $52-$55). THe car was recently serviced with the valve cover gasket replaced.
- Q: How come my boiler supply valve isnt letting water into my boiler, i have a cold water supply hooked up to it with the valve on i have tested the copper pipe goin into it and water flows into it, but when It reaches the valve it stops. I understand that it my have a backflow preventer in it and I am wondering if that could be malfunctioning. The hole you see on the front is where my expansion tank screws in. Also where could I get a new Valve. Thanks.http://img149.imageshack.us/i/boilerfillvalve.jpg/
- I work on antique steam boilers and engines for a hobby and if your supply valve isn't letting feedwater into the boiler, I'm going to tell you right now that you potentially have a VERY dangerous situation on your hands. Until you get this issue resolved, I would recommend that you not steam this boiler up under any circumstances, unless you have a backup feedwater delivery system that is working correctly. Many people don't know this, but a low water condition in a boiler under steam is essentially a ticking time bomb and can result in a fatal explosion. As to what may be causing it, I would say it's possibly one of two things: 1.) The check valve has been installed backwards and the flow of water is basically pushing it shut. 2.) The check valve is installed correctly, but is frozen shut due to corrosion and scale. Either way, I would have a certified boiler inspector come out and take a look at it; he can probably tell you more than I can.

- Q: my Hunter SVC VALVE will not work with my Lawn Genie Valve. Is this becaous the voltage is not matched? Hunter says it operates solenoids at 6-9 v DC // Lawn Genie says it is an 18 v DC solenoid. :-( my original Hunter Valve broke and I replaced it with the Lawn Genie. Should I get a Hunter Valve , or a Lawn Genie Controller at this point/ or is there something I have overlooked?.
- Something is incorrect. All valve solenoids and all timers are designed to work at 24 v DC It should make no difference which brand of clock or which brand of valve you are using. Now the actual solenoid which is the circular cylinder with the wires coming out of it that screws into the valve may not fit all brands of valves but you can buy the correct brand to fit your valve at any irrigation supplier. If your controller is working with at least one valve it should work with any valve you have installed. I would look at the wiring and see that they are correctly installed and connected especially at the valve. If one of the two wires is loose or connected wrong then you wont get the valve to operate. If you have a voltage meter I would test it with that. If not make sure at least one wire from each valve is connected to the white (or nuetral wire) out of the controller and the other valve wire is connected to one of the hot wires coming out of the controller. If one valve does not work try connecting a hot wire off a working valve to the non working valve and test it. If it works your problem is in the wire you disconnected. I constantly work on sprinkler systems and wiring is no. one problem. Incidently I cant find a SVC valve listed in the Hunter catalog did you get the letters mixed up?
