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 noticed when I pulled my pcv valve off the valve cover the entire guts were missing. what would this make the car run like?
- what it really is is a check valve it will flow one way but not the other meaning it lets the motor vent out pressure and no air or debris can be sucked or drawn in its better to have a functioning one cause it can affect performance overall cause it usually is working with emissions devices now to be honest replacing it is almost mandatory, but you actually might not notice any difference at all after its fixed
- Q:Hello all,I have a1990,BMW 525i.I bought this car from another guy about year back and drive around 13000 kms.1.Do i need to adjust the valves(both inlet and outlet).2What is the importance of valve adjustment3Does it affect the mileage4.As a regular maintenance for how many kms can i drive without valve adjustmentExpecting your valuable replies.
- Benefits Of Valve Adjustment
- Q:I just bought my first bike in 20 years, and as a result have had to pump up a bike tire for the first time in 20 years. I was dazzled to discover a type of tire valve that I'd never known about. The Presta.So of course, I need a pump with a special adapter, I didn't know to unscrew that nut at first so I accomplished a whole lot of nothing for awhile, and once I did open the nut, the pump kept slipping off the tire once I got anywhere near the tire' recomended PSI until I awkwardly held it in place while operating my pump with one hand, which of course meant less leverage and so while I got above the min recommended PSI, I couldn't get anywhere near the upper end of the spectrum. Why would anyone use these ridiculous contraptions? The fact that they are used means there must be some rationale. A brief internet search seems to find more forum posts with people saying the alternative (Schraeder) valves are more reliable and don't leak as much either.Educate me!

- Q:What is the specific use of an angle valve
- I okorder /... I hope that I adequately answered your question. Wingman
- Q:I have a 99 Yamaha Warrior 350 and i am needing to take it and get the valves adjusted. I know prices will range from state to state but what would be the average price to take and get them adjusted?? Just the valves not including if they had to change the seals or anything.. Thanks(PS im a girl so put it in simple words!)
- The link below shows what the valves are. The adjustment to them requires loosening #13, and then turning #12 such that the valves #1 2 are within the proper specification. To do this requires disassembly, then measurement and adjustment, and finally reassembly. This can range from 1.5 to 3 hours depending on various reasons. So, estimate 3 x [Labor Rate], whereas [Labor Rate]s vary from shop to shop, and I've seen from $65 to $120.
- Q:Do blow off valves serve any purpose besides making the hiss when you shift? how much does one cost?
- Blow-off valves only work on turbocharged or supercharged engines. It is an intake manifold pressure regulator. I've seen people put them on regular engines thinking they would hear that hiss, but there is no where near enough pressure for them to do anything.
- Q:I want to put a blow off valve in my car to make it sound cool lol but i dont have a turbo yet ... do i even need one?
- Buy a compressed air tank that you can fill at a gas station like you would air up a tire. Mount this tank in your trunk and route air hose from the trunk through the passenger compartment and into the engine compartment. Add a simple valve in your center console or wherever you prefer to turn the air on or off. Drill a hole though your hood and affix the air hose to it. With the air tank filled up, just open the valve and WHOOSH, instant blow off valve sound. You could even fill the hose with confetti for a colorful display. If you wanted to get real fancy you could rig up an electric air compressor under your hood for a continuous air supply. Thats the only way you cant get the release of compressed air to make a blow off valve sound without a turbo. Oh, and while you buying all the supplies for this don't forget to get some fake spinner bling-bling hub caps!! Then you will have the ultimate pimped out ride!
- Q:OK, I would like to run my shorty headers open on my Camaro, but I have two questions.1. I heard valve damage may occur because cold air gets in there. Why isn't this the case with straight pipe exhaust, doesn't the cold air travel to the valves in that case anyway?2. Right now with my headers to off road y pipe I have 2 o2 sensors to throw the check engine light off, and it has worked. If I run open headers, will they still work?
- Cold air doesn't get in to damage, but the valve needs a bit of back pressure. The valve will burn, crack or check, or the valve seat will do the same. The common damage is a small w crack on the valve face, which then leaks compression gases into the hot header resulting in erratic backfire and misfiring. The lack of back pressure can be compensated for by richer mixture, or grinding a wider seat. Get used to lapping in valves, or find some high performance sodium valves and stelite seats. You could run dumps, and only open the headers for short blasts.
- 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 have a 3-circuit sprinkler system in my yard (built by me, last year). I discovered this week that I overtightened the connection between the valves and the downstream pipes, and 2 of the three valves are cracked, and leaking, at the connection. I replaced all 3 valves, and now I need to reconnect them to the supply. But this means I'm working backward - when I bult the system last year, I worked downstream - I built the manifold first, connected the valves, then the remainder of each branch. Now, I have to make the new manifold fit the valves, and naturally, they don't line up perfectly. Any tips/tricks on connecting valves in this situation? Is there such a thing as flexible pipe that can withstand continuous pressure? I'm using unions at both ends of each valve to help things go together/come apart more easily.
- valve manifolds are something that requires practice and experience. i used to struggle with them at work until i did a good bit of them. 3 zones is not that many valves so it shouldnt be too difficult. if they wont line up exactly right, i would recommend adding longer peices of pipe to the mainline side of the vavles and re routing the supply line futher back and you will have more room to flex the pipe and vavles into the Tees and 90s. do not use any form of flexible pipe on any mainline. you will regret it. lol the bigger the hole you dig will give you the most room and the more pipe, and room will give you more flexability to build the manifold. it is easier to connect the valves the way you did it first though, but you can do it either way. good luck and hope this helps
