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: Ive been tolding one or more of my valves is/are knocking, how can I fix this. Detail would be great, this is for a F0RD 460, from a 90. I was wondering if I can just buy some used heads(not sure if this comes with these things called valves, haha)but I can pick up some 460 heads, for pretty cheap.. on those and do a full swap, since mine is from 90 i dont know if year would matter. So how can I fix knocking valves., thanks
- Valve noise is usually caused by a bad hydraulic lifter, or a worn cam lobe, sometimes wear in the rocker arms also. I don't think changing the heads would help much in your case. I woud get a good mechanic to listen to it, and tell you first ok, because sometimes, just changing the oil and putting in an additive will stop noisy valves good luck
- Q: So just yesterday i bought a second-hand ytr 2320e. After i bought it, i washed it and tryed playing it, but when i press the first valve, there is this small metal scraping metal sound kinda like if you scratch a metal bowl with a fork. I think it has something to do with the spring but im not sure.also, i was wondering if the trumpet valves are supposed to be very easy to press, or if they take a tiny bit of push.
- I don't think anyone knows, because there's multiple Bibles. And people interpret it their own way, and re-print it with different scriptures. As far as I'm concerned, there is no such thing as a REAL bible anymore. And any beliefs we have today about it are all false. According to one bible, you will be sent to hell on both counts. According to a modern version, you will be excused for doing your wife, and in another bible, you'll be stonned for asking this question (Knowledge is a sin) Interesting that we are the only intelligent life on earth, supposedly made in God's image, and yet the bible says to stay away from the tree of knowledge. Sorry, I don't buy into that bullcrap.
- Q: IT USUALLY TAKES 2 SECONDS TO START THE MOTOR. NOW, IT TAKES OVER 40 SECONDS AT 7 AM. IT ALMOST KILL THE BATTERY. IF YOU PARK FOR 1 HOUR, 2ND START TAKES 10 SECONDS. IS THIS HAPPENING BECAUSE THE VALVES NEEDS ADJUSTING? HOW AND WHAT IS THE EASY WAY OF VALVES TUNE-UP?
- Good call, it most likely is the valve clearance. As the valves wear, they get tighter until they actually stay open a bit (when cold). As the engine warms up, the aluminum head pushes the cam away from the valve stems a bit, and some clearance comes back. Check 'em, adjust 'em, and you should be good to go. For most chinese 150's, you'll need to remove the plastic around the engine, then pull off the valve cover - you'll see the rocker arms inside, with locking nuts and adjustment screws. Set the crank at TDC on the compression stroke (about 1/2 turn after the intake valve closes) and then adjust the clearance - get specs from your manual, or just make sure that there's at least 0.1 mm gap if you don't have the specs.
- Q: Hi guys, Thanks for your advice. RandyK is right, my dad's GP told me that if we don't get the valve operation, his heart will swell in years time and might cause more complicated illness. Just let you know my dad had seen his cardiologists recently and had some scan or tests done. The results will be discuss in next appointment, they suggested that mechanical valve would be used if the operation go ahead. At the mean time I just hope and pray his condition will under control by medication. Wendy, may I ask you how old are you when you had your valve operation? I am too scare to suggest or encourage my dad to do the operation. Because if there is any difficulties or worse ...during operation, I will be the one send him away......If anyone have a relative like my dad's case,(76 years old had valve operation) please give me some advice.. Many thanks
- A friend 65 and I , age 61, had our mitral valves replaced this year. I felt very tired at first. Barely could get up into a pickup truck. My chest felt stiff with difficulty raising my arms. I slept on a couch with 2 pillows awhile. If I laid down flat on the bed, I could not breathe comfortably. It felt so great to be able to lie down flat on the bed after about a month. I had little twinges in my chest occasionally. It has gradually gone away. After 6 months, I feel great and can do all I could do before surgery. I go to water aerobics 2 times a week and walk my dog. Many people are getting valves replaced at ages 60 and 70.
- Q: Are these valves are a kind of heart chambers pressure sensors?What is keeping them interlocked 2x2?
- It's all mechanical. The valves are passive things kind of like a screen door. When you push on them from one side they open, when you push on them from the other they close. The valves are assisted by some fibers attached to the inside of the heart similar to the way a screen door is helped by a spring attached to the door frame. It's the flowing blood that pushes the valves open or closed as the heart pumps. The path that the blood follows in the heart as it beats happens to make it so that the valves close two at a time. This is because the heart is actually four separate pumps that work two at a time. There's no direct electrical connection to the SA node. The only way they're connected is that the SA node firing is what causes the heart to pump, causing the blood to force the valves open.
- Q: I got new sprinkler valves put in (Rainbird anti-siphon kind). Every time a valve shuts off, it makes a loud squeak, kind of like plastic rubbing (NOT a bang like water hammering). Is this normal and will it go away? If not, what could be the problem? This is annoying because the sound can be heard in the house as it echoes through the pipes.
- As the valve shuts down, the diaphragm will vibrate as the pressure changes from one side to the other, then it will Thump as it seals. This is normal. However, to isolate the squeak, you may check to see if there is a 1(backflow preventer installed, 2) (if built into the valves) the variable pressure screw on the top of the valve is set correctly. The variable pressure screw usually has a cross top handle (older ones had a dial) and should be set so that on a high pressure line, it shuts down fairly quickly. If this is open all of the way, it can cause the diaphragm to squeal by slowing the internal pressure change to shut it down.
- Q: 1995 Yukon need valve lash adj- how and hat tools?
- remove valve covers, watch front left two lifters and turn engine, by bolt that holds harmonic dampener to front of crankshaft, so mark on dampener lines up with mark on front cover. If rocker arms do not move as marks line up engine should be on top dead center number 1 cylinder. Now you can adjust exhaust valves 1, 3, 4, 8 and intake valves 1, 2, 5, 7 [ odd numbers are on the left bank from the front 1,3,5,7 even on the right bank from the front 2,4,6,8]. Adjust by turning nut in rocker arm out until movement is felt than tighten until all movement is gone and tighten one turn more. After done with the first eight valves turn engine over one full turn till marks line up again. Then adjust exhaust valves 2,5,6,7 and intake valves 3,4,6,8 the same way.
- Q: im looking for the egr valve on a 97 mazda 626 its not in top of engine like other cars where can it be?????o and its a 4 cylinder
- Dont know about your car, but look near the intake by the fuel rail
- Q: My pressure reducing valve (or restricting valve) was looked at by three master plumbers and they all said I need a new one. My water pressure has been low for weeks. It measures about 100 psi at the outside hose bibs, but it is very low inside and suddenly reduces after you turn on the facets inside. The shower is ok. My automatic sprinkler system is not able to work now due to low pressure. A relative of mine thinks we can just add a handle (as one is missing) on the valve and adjust the pressure ourselves. The repair of the valve is around $500-600! I am told in Texas that we have to have a permit and inspection to repair this valve. Also I was told by the last plumber that came out, that I have to install a expansion tank on my new hot water heater according to code. I'm not sure if that is a city code or federal. Please respond as to information you may have on this problem. The expansion tank is required I'm told when you have a pressure reducing valve for safety, is this true?
- The cost you quoted seems a bit high to me. Mine didn't cost anywhere near that amount in East Texas. A pressure reducing valve acts like a check valve when there is no flow. That is it closes as the pressure rises when you are not using any water. In this condition, the hot water heater can raise the pressure even higher since there is no place for the expanding water to go. That is the reason for the expansion tank. Without the expansion tank the pressure relief valve on the hot water heater can relieve unnecessarily or weep a bit.
- Q: hi ihave a 2001 1.4 civic (6th gen) has anyone got any info/reviews on the following mods: powerboost valve, denso/splitfire spark plugs(which one would be better) and splitfire ignition leads.
- While I'm not familiar with the power boost valve specifically, it looks similar to a rising rate fuel regulator which is used more for forced induction applications like turbocharging and supercharging. If you were to install this on a relatively stock car you would risk running an extremely rich mixture that the stock ecu would be unable to compensate for which in turn could cause damage to your engine. The stock fuel regulator that currently sits in your car is more then sufficient enough to keep up with simple bolt on parts and shouldn't need replacement unless you are planning on doing true engine work or forced induction. As far as comparing different companies' spark plugs and wires it would really be a matter of splitting hairs.
