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.

Q3:How can I place an order?
The only one thing you should do is to tell us the sepecification about type 、quantity and mode of transportation, then we will send you quotation within 24 hours.
- Q: The water in my tub/shower stopped working. I did my research on the net to discover the cause and I also went to Home Depot explained the problem. The worker at home depot helped me get the right part I needed to replace the valve stem. I came home, took the faucet handle off and can see what I need to do next. Everything seems perfect and ready to go, except I can't remove the old valve stem. It seems like the old one should just slide out and the new one replaces it. How do I get the old one out without damaging any of the pipes or hurting myself.
- Do you have a valve for the hot and one for the cold, or does one valve control both? If there are two valves they should just unscrew. You might need to go back to Home Depot and get a wrench designed for valve stem removal. (Before you go, spray it with penetrating oil such as WD-40 and let it do it's thing while you're gone. If it's just one valve for both, there's probably a collar that screws on and holds the cartridge in place. After that is off, the cartridge should slide out-ususally with a little 'persuasion' from some pliers. (But don't try to twist it) Hope you get it.
- Q: There has been brake fluid leaking below where the Master Cylinder was and pinpointed that the leak was at the base where the steel lines and proportional valve intersect(kinda sprays out out like if a seal is bad or someone didn't tighten enough). Any way to fix this or replace? Vehicle is a 1988 Plymouth Reliant (2.2 liter) Auto, no ABS.
- If you are not familar with brakes I wouldn't suggest tackling this job yourself. You will need to take the line off in question to condemn either the prop valve or the line. I have never in my life seen the line itself leak but I guess it's possible. The valve is a dealer item only, whatever you do, dont buy it from a junk yard. After replacing the valve, if that is what the problem is, most likely you will need to get a brake power bleeder to get all the air out of the system. I would estimate through a shop and the typical mark up on the part, shouldn't be more than 200-225 parts and labor including the brake flush, good luck.
- Q: I have a 1989 Jeep Cherokee with 218,700 miles on it and my engine has thick oily gunk on it, possibly from a leaky valve cover gasket, should I change the gasket? I have been told that this is normal and not to worry about, but from the amount of this gunk, I find it hard to believe this is normal. The top of the valve cover has a light covering of gunk, but on the sides and towards the bottom of the engine. it gets very thick and at some places you can't even make out whats suppose there. Does a leaky valve cover gasket mean that there is another problem going on?Can leaving the oily gunk on the engine cause any problems?Any info would be greatly appreciated.
- Not to be mean but you can't work on what you can't see! Take the Jeep to a wand type car wash with a bag of quarters. Lift the hood and spend some time with high pressure soap and clean the entire engine and under-hood compartment. Don't bother covering anything. Leaking valve covers don't mean anything is wrong, it just makes a nasty mess. Remove valve cover/s and scrape old gasket material of the head/s and cover/s. The best valve covers in the world won't seal until the valve cover/s are completely flat. *This is an age old problem with stamped steel covers. If you want to get extra slick, chase down some aluminum cover/s. There stiffer and less apt to leak when you snug them back down. I'll let you in on a racers secret to make them seal. Buy a tube of Dow Corning or Permetex clear RTV silicone sealer. Scrape down the valve cover gasket surface till it's clean. Wipe the gasket surface down with CRC Brake Clean. Run a bead of the clear RTV on the valve cover and let it set-up for at least five minutes. Lay a Fel-Pro - Blue Stripe valve cover gasket on the valve cover. Seat it with your thumbs. Scrape-down the cylinder head where the gasket goes till it's perfectly clean. Clean the gasket seating surface on the cylinder head with C5RC Brake Clean. Lay a small bead of the RTV on the outside of the gasket which will meat the cylinder-head. Carefully set the cover on the head and gently alternately tighten them. It's OK to drive the vehicle as soon as you're done!
- Q: Movers messed up the valve so hose won't screw in w/o leaking
- Buy a new valve at an appliance parts outlet. Make sure it's the right one. Many times they will come with instructions. Unplug the unit. Shut off the water and remove the hoses. Remove the back panel to access the valve. Remove the old broke valve and replace it with the new one. Replace the panel. Attach the hoses and turn on the water. Check for leaks. Plug in the unit and give it a test. Try all the temperature settings. Congratulations. You are now a professional..
- Q: I just installed a iac valve on my 2001 blazer but didnt go through the reset steps. Do i have to unistall and do the steps or go from here with the reset. Truck stalls out now and surges... Or could i just hava a defective part.

- Q: My vehicle has 160,000 miles and has burned 2 quarts of oil at 3000 miles. Someone told me to change the PCV valve because sometimes a bad PCV valve can cause oil consumption. I appreciate your assistance.
- the pcv valve is on the valve cover just pull it up and it comes right out, if you see a hose going from the valve cover to the intake manifold thats the one . You also might want to make sure you are using the right oil for your truck for that truck ford recommends to use 5w-30 oil. Perform a cylinder compression test or perform a cylinder leak detection test with Engine Cylinder Leak Detection/Air Pressurization Kit. This can help determine the source of oil consumption such as valves, piston rings or other areas. Worn or damaged internal engine components can cause excessive oil consumption. Small deposits of oil on the tips of spark plugs can be a clue to internal oil consumption. Other problems might be: Sticking valves, worn valve guides, poor valve seating, burned or warped valves, worn rings. Perform a intake manifold vaccum test, that will help determine the problem.
- Q: Is there any application usuage of ball valve in comparison,most engineers opinion is as Valve size get reduces in reduced port.Other than this what paramteres decides in selection of either of one

- Q: Can leakage of heart mitral valve be treated with homeopathic medicines?My grandmom has leakage in mitral valve. I am searching for options to other than surgery to make it less painful for her. She' is above 80yrs of age. If you know of any good options for treatment , please let me know as we also consult the doctors. thank u :)
- Homeopathic medicine is definitely not the way to go. Do some research on how they get to the final solution they sell you.
- Q: The pig heart is better than our heart but the valves can be used to help us.
- I have had heart surgery and they ruled out replacing my valve with a pig valve because they only last about 5 years. They replaced mine with a mechanical valve, and so far it's amazing! If they replace your valve I believe they basically cut out the defective one and sew in a new valve, animal or man made. If replaced with a pig valve you must be on anti-rejection medicine, and have it replaced every five years or so. With a mechanical one you have to be on blood thinners, but they assume (last I heard) they should last a minimum of 40 years, probably longer.
- Q: what is engine valve timining ?
- The valve's are in the head or head's and they need to be lined up with your crankshaft in order for the engine to be in time , if they was'nt in time with the crank they would hit at the wrong time and your engine would be junk.
