FAQ of Cast Steel Check Valve:
Q1:I can’t find the type of steel check valve which I need. what can I do?
The chart above only lists out some common composition of steel check valve parts.We may provide other different parts material composition according to the customer's request or the actual valve working condition.
Q2:Which certification do your products pass?
Our products are in accordance with ISO 9001、ISO 14001、API 6A、API 6D、TS CE、API607/6FA/BS6755.
- Q:I had to replace the gaskets on my valve cover only to discover that the valve cover had developed a hole due to oxidation. I waited a week for a new valve cover to come in and left the engine exposed. Should I have any issues? I mean its covered but its still outside. Should I pour some oil on the exposed part of the engine?Its been already about a week.
- So long as it is covered you will have no problems. The hood closed, maybe a rag over the hole... I wouldn't give it a second thought.
- Q:this question was on my test for APII, the question is stated as:the tricuspid valve is closed...a) during rapid filling of the ventricles (this is the answer the teacher shows to be correct)b) by contraction of the papillary musclesc) while the atria contractd) during ventricular contraction (this is the answer i chose i got it wrong)please let me know to correct answer!! thanks!!
- The bicuspid valve is the left atrioventricular valve, and the tricuspid valve is the right atrioventricular valve. Blood enters the heart via the Superior Vena Cava (and Inferior Vena Cava) into the Right Atrium. In between the Right Ventricle and the Right Atrium is the Tricuspid Valve. The right ventricle receives oxygenated blood from the right atrium (as it contracts). Once the ventricles are full, they contract and the tricuspid valve shuts and the pulmonary valve opens. This makes sense for the tricuspid valve to shut (preventing regurgitation or backwash) while the blood flows through the open pulmonary valve into the pulmonary artery (to the lungs.) I would not have chosen a) or c) for an answer. You can rule out b) for an answer because the papillary muscles contract opening the tricuspid valve. You chose the correct answer, d) because once the ventricles are full they contract causing their respective valves to shut.
- Q:I play the trumpet and I took it home for Christmas Break. On Friday I am playing Amazing Grace at Church for New Years Eve, but the problem is my valves on my Trumpet is sticking and I don't have any valve oil for it. Is there any other oil that I can use for the Valves? It will be really great! Thanks :)
- Unscrew the the valve cap on the main suitable decrease than the button. attempt to softly pull the valve out. you could might desire to paintings it backward and forward until it loosens up you could upload some oil around the the sting of the valve cylinder. as quickly as you have all 3 valves out sparkling all the debris off of the valve, you ought to use an sos pad to get a number of the heaver stuff off. Wipe each ingredient off with in straight forward terms somewhat of lighter fluid and a sparkling rag. sparkling the valve bores including your snake. Stuff a rag down each hollow to get the stuff the snake loosened up. Reoil the valves and the cylinders and reassemble.
- Q:i wanted to know what is the actual difference between check valve (non return valve) and globe valve?
- A check valve stops water from going back through the water line . A globe valve is a type of valve that uses a ball shaped device with a series of holes which regulate water flow , normally found in household water supplies. The other type of valve is a gate valve, which is used where a larger flow is regulated, like in most commercial applications.
- 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 mechanics charge about $40. But, you can learn to do it yourself it is easy. Just loosen the outer nut. Turn the center one til it touches. Then back it off 1/8th of a turn. Then while holding the center one tighten the outer nut. Then your done with that valve, and repeat for however many valves you have.
- Q:Can sum1 tell me how i can tell if my valves are in the right place?I notice there are holes in the valves, please explain how those holes are suppose to face to for each of the 3 valves?
- Put the correct valve in the valve case. (There is usually a notch that guides the placement, but it is not always accurate enough.) Blow gently into the trumpet, (you don't need to play, just blow as you do to clear the spit valves). If you feel a resistance, rotate the valve until the resistance is gone. When there is no resistance with the valve up, depress the valve and blow again. There should be no resistance there either. Repeat with each valve.
- Q:So I tried to go skydiving last weekend and they told me know because I have mitral valve prolapse. I've had it for years and it's never really been a problem for me, I just have chest pains sometimes and feel palpitations. What would be the danger of not telling the skydiving place about my problem the next time I go in? I know I should tell them, but I want to skydive. What could happen to me if I jump? No lectures about what's right and wrong here please. I just want to know what's the worse that could happen?
- There are many people with mitral valve prolapse that never have symptoms related to it and never have any problems as a result. Mitral valve prolapse can lead to the backflow of blood through the mitral valve known as mitral regurgitation. This can potentially lead to abnormal heart rhythms, such as atrial fibrillation. The concern with skydiving is that it would lead to a surge of adrenaline resulting in increased heart rate, strength of heart contractions and overall workload of the heart. If you have MVP without regurgitation, then your risk would be similar to the general population. If you have regurgitation it depends on the severity the regurgitation. If you have mild regurgitation, then it also should not be a problem. If you have severe regurgitation, then you could run into problems from the increased workload of the heart. In this case, I would suggest you discuss it with your Cardiologist. It is unlikely that you have atrial fibrillation. If you by chance do, then it depends on how well your heart rate is controlled. If there is any doubt, then ask your Cardiologist. Good luck.
- Q:Hi all,My buddys ford 460 has stuck valves. Where do I start? Could I notice anything by removing the valve covers, or do I have to remove the heads? Is it possible to unstick them without removing the heads? Assuming they stuck from sitting. What's the chance it bent the pushrods if it was running when they stuck? Can I check this without removing the heads? I'm not too familiar with this engine.
- a valve stuck in the open position when cranked by a starter motor can put a hole in the piston it depends on which 460 7.5L you have some are flat top some are popups where centers are raised ive seen both in stock motors motorhead is right you can free them but you'll wanna soak them down constantly for a week or so remember they didnt get like that over night DO NOT crank over with starter use bolt on balancer as you'll feel resistance should you encounter a stuck open valve its so much easier with heads off but you can see the guides by removing valve covers if your valves are stuck your guide seal are junk trust me
- Q:I have a '98 Dodge Caravan 3.0 and the valve cover gasket is bad. How do I replace it?
- you are going to not like this first drain coolant 2 remove the throttle body linkage remove the pipe going to the egr to exhaust manifold [helps to use penatrating oil] remove assorted hoses to get to removing the upper intake plendeum {not the lower intake] [you need to put a shop towel over the open intake ports at the engine to keep any and all debries out of the intake ports to the engine] you should be able to see the valve covers by now remove the valve covers bolts remove the valve cover clean the gasket surfaces on the cylinder head [don,t leave ant debries in this area or in the valve cover [cleanlyness is a really good thing at this point in the build keep the crud out] there are some half moon seals that need to be replaced at this time located on the ends of each cylinderhead put a light bead of RTV high heat silicone on the rounded side of the seals and install the seals in thier half moon bores the RTV high heat silicone will kinda squish out of the seal don,t let the beead get carried away wipe of the sealent with a clean towel [shopcloth] not paper towels put a little RTV high heat silicone across the seal s flat side wipe flat with your finger install the valve cover gaskets on the valvecover [a little automotive contact cement for weaterstripping helps hold the gaskets reinstall everything fill coolant system change the oil and filter look for leaks a book or parts guy should be able to help find the right touque to tighten the bolts remember cleanlyness works here good luck should take about 8 to 10 hours note do not reuse any gaskets any where new hoses would not be a bad idea along with a thermostat ihawk3
