FAQ
Q: Are you manufacturer of trading company? Which kind of valves do you supply?
A: We are a professional manufacturer of butterfly valves, check valve, non-return valves, gate valves, Y-strainer and so on.
Q: Will you do inspection before shipment? Whether Third Party Inspection is available?
A: We have a professional engineer team, so we can offer you the most professional technical support. All valves are tested twice before and after hammer pin to ensure its perfect sealing property and to make sure every valve is ok before ex-factory. TPI is ok but the clients should bear all fees.
Q: What kind of package do you use for these valves?
A: Valves from DN80-DN1400 will be packed in wooden boxes, but valves above DN1400 will be in wooden pallets. If you need wooden boxes for above DN1400, the price may be more expensive.
- Q:Also, Is a pneumatic control valve an ATC or an ATO; is it a FO or FC valve?
- THere are a large number of types of valves; ball, gate, globe, needle, etfc. I suggest you look up valves on wikipedia. ATO = air to open; the valve has a pneumatic operator with a spring returning it to closed when the air pressure is removed ATC is the reverse FO = fail open; if the actuator fails the valve will be open. Actuators are made ATO, ATC, and air to move either way [no spring]. The latter would be your FLP. Control valves, by which I mean a proportioning valve or valve with a variable open area, with a 3-15 psi control input, are usually ATO.
- Q:i wanted to know what is the actual difference between check valve (non return valve) and globe valve?
- Check valve/non-return valves are unidirectional, meaning flow can only go through them one direction. Check/Non-return valves usually don't include any kind of manual actuation. Globe valves have a sphere with a hole cut through it, as the globe is rotated within the housing, the hole aligns with the valve inlet and outlet, or is sealed from the inlet/outlet by the valve casing. Thus, the handle/knob is used to rotate the ball, thereby opening or closing the valve. Because the hole is cut cleanly through the ball, flow through a globe valve is bi-directional.
- 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.
- No, there shouldn't be any scraping sounds. Yikes! It may be simply that the spring guide is misaligned. I'd pull the valve and try to make sure it locks-in when you replace it. On Yamaha's, the valve guide locks in with the valve facing forward (or backward - but you won't be able to blow through it with the valve down). So pull it. Look to see if there's a number engraved on the top section of the valve, and if so... it faces the player. Once you slide it in, turn it side to side slightly. If it won't turn, the valve guide is in place. If it turns a little, you should eventually hear the valve guide snap into the groove and you won't be able to turn it. If the scraping sound continues, the spring may be bent and need to be replaced (easy do-it-yourself kits available on-line). As to the sound, my guess is that this is just a matter of adjusting to a MUCH smaller mouthpiece than you're used to using. Everyone sounds awful when they start. That said... You should also check to see that the spit-valve corks are there and sealing the tuning slide and third valve slide completely. They'll fall off sometimes, which creates a leak and thus an annoying buzz in the sound. It's a good student model trumpet, so congrats on the purchase, and enjoy!
- Q:Kenmore washer ,cold water trickles in, pressure from faucet OK. Must entire valve be replaced?
- You probably can not find a rebuilt valve or get the parts to rebuild one. If needed, it will probably need to be completely replaced. There is a good chance you do not have a valve issue. Turn the water valve off and remove the cold water line at the back of the washer. Inside the hose or on the washer itself, there should be a metal screen in the line that somewhat filters the valve and protects it from getting clogged with sediment. Remove the screen and clean or replace it. If the screen wire is not at the washer end try the valve end of the cold water line. While your there you may want to clean the hot water side also. If you are unable to clean the screen, new ones are available for minimal money at hardware stores. Yes the screen wire is necessary, by removing the line additional sediment may very well go into the valve when you turn on the water and cause a valve problem if you don't have one now.
- Q:My friend is having 3 valves in her heart replaced with pig valves. Her dr said that putting in human valves raises the risk of her body rejecting them but wouldnt your body also reject a part form different species? And if they only last a few years why use them at all? shes all freaked out about the surgery so I dont want to ask her too many questions
- We recently demonstrated a third possible replacement material: fresh porcine valves . Fresh porcine valves are immunologically privileged, as they do not express -Gal, the carbohydrate antigen that is responsible for the rejection of porcine hearts. Consequently, even when wild-type porcine hearts are destroyed by primate immunoglobulin M (IgM) and membrane attack complex (MAC) deposition within 60 minutes, the valves remain structurally pristine.
- Q:Just wanted to know what the significance of the number of valves is?I know that theres valves for intake and exhaust if i'm correct.if there is four i'm guessing its 1 for air and 1 for fuel if its fuel injected. and 2 for exhaust?are there bikes with 3 valves or more than 4 valves and why?and a basic carburated 2 stroke just has an intake from the carb side and then an exhaust.please give me more info and let me know if i'm correct or not.
- 3 valves: 2 intake, 1 exhaust (Honda CM400/450, for example) 4 valves: 2 intake, 2 exhaust (very common) 5 valves: 3 intake, 2 exhaust (some Yamaha sport-bikes) 8 valves; 4 intake, 4 exhaust (Honda NR bikes only) Multiple valves allow much greater flow at partial valve openings, when flow is dependent on total valve circumference, rather than total valve area; Multiple valves each weigh less, allowing a higher rev ceiling without valve float;
- Q:i just replaced the head gaskets on my 1991 Acura Legend and When i put the timing belt on somehow it slipped and came loose I than tried to start it(not knowing it came loose) and it cranked hard and strong but no start. I just retimed the engine and put new timing belt set on it and when i started it the car blows grayish blackish smoke from the exhaust and has a really crazy idle. Could the valves be bent
- if it bent the valves it probably wouldn't run at all. it sounds like you may be off a notch on the belt timing. to be sure you didn't bend the valves you should check the compression. if valves are bent there won't be any compression. hopefully you didn't. I don't access right now to see if it's an interference engine or not.
- Q:My baritone is somewhat new, the first valve isn't going down, I've tried nearly everything and I want to avoid taking school instrument to a music store to repair.
- If valve oil alone isn't working, try flushing out the valve casing with warm (not hot) water. Likewise, rinse off the valve itself. Once they're dry, apply a fresh coat of oil and try again. Also be sure that you have the valve aligned properly. Now if the valve still doesn't work, then it may be time to bring it in to the shop.
- Q:i have a 1987 nissan 300zx and i can get the car to start unless its 40 degrees and when it does it idles hard. is this idle control valve or a fast idle valve??
- Could be.. Also could be dirty. Easy fix, remove the valve and spray carb cleaner in the hole.. Using a small brush, clean the bore that the valve rides up and down in. Also, inspect the valve while it is off the manifold. Harder fix: After cleaning the bore, replace valve with brand new one. Your car will have to relearn the idle after starting with the new valve or after you put the old one back in.. Start car, but do not put it in drive or give it any throttle until the computer has finished making adjustments. - Dave. (Long Island, NY)
- Q:right after it come through the foundation. Should it be a gate valve?
- Gate valves used to be the standard, but Globe valves had replaced them, and now Ball valves have replaced them. A ball valve is the type of choice these days. They have the best reputation for shutting off completely and have a VERY low failure rate. Al
