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: Tryin to figure out how many valves a 1992 vx has. 16 or 8?
- '92 Civics had single overhead cams (SOHC), so they have 8 valves. 1 intake valve and 1 exhaust valve per cylinder, so since there are 4 cylinders, that makes 8. Vehicles with dual overhead cams (DOHC) had 16, but Hondas had SOHC cams at that time. I'm really surprised how many people are saying 16. That is incorrect. I am positive. You cannot have 4 valves per cylinder (total of 16 valves) on a motor that has a single overhead cam.
- Q: I have mitral valve prolapse, I want to continue lifting weights.. Can i lift weights?here's my latest echo result.1. Normal left ventricular size with non-thickened walls with adequate wall motion and systolic function (EF = 70%)2. Normal left atrium without intracardiac thrombus3. Normal right atrium, right ventricle, main pulmonary artery and aortic root dimensions.4. The anterior mitral valve leaflet prolapses into the left atrium during ventricular systole.5. Structurally normal aortic valve, tricuspid valve and pulmonic valve.6. No pericardial effusion noted.COLOR FLOW DOPPLER STUDY:No abnormal color flow display across the valves, interatrial and interventricular septae.Normal pulmonary artery pressure by acceleration time.
- overall picture doesn't prevent you from doing mild to moderate exercise, but with wait lifting we should think twice.
- Q: what is a foot valve? how does it look? what is the application in petrochemical companies?
- A foot valve is simply a check valve. It is common use in a piping system at the pump suction side. By placing it this way when the pump stops operating, fluid won't flow back into the lower reservoir and the suction side of the pump is always full of liquid.
- Q: What are the benefits of changing new cylinder heads and exhaust valves in the Main engine of the vessel? I am now studying a vessel which has a problem with their main engine. Frequent repair of cylinder heads (they usually weld it) and exhaust valves are the ones they do. I need to further give the benefits to be submitted to the vessel's management for them to buy new cylinder heads and exhaust valves as a replacement for the welded ones.
- To answer your first question only, the benefits of changing cylinder heads and valves would be to improve the overall performance of the engine, like increasing its horse power, speed and fuel consumption. To prove to the vessels owner that this needs to be done, a compression test should be done on each cylinder by a mechanic. This will show how each cylinder is functioning, and the results need to be cross referenced with the compression specifications for that specific engine.
- Q: if safe, at what age should a woman with mitral valve prolapse be pregnant?
- My daughter was diagnosed with MVP at age 14. She has had 5 pregnancies, 1 miscarriage and 4 deliveries. That's 4 deliveries in less than 5 years. The obvious answer here is to talk to the OB that will deliver you to have your particular case evaluated since we don't know all the details.
- Q: How come my boiler supply valve isnt letting water into my boiler, i have a cold water supply hooked up to it with the valve on i have tested the copper pipe goin into it and water flows into it, but when It reaches the valve it stops. I understand that it my have a backflow preventer in it and I am wondering if that could be malfunctioning. The hole you see on the front is where my expansion tank screws in. Also where could I get a new Valve. Thanks.http://img149.imageshack.us/i/boilerfillvalve.jpg/
- I work on antique steam boilers and engines for a hobby and if your supply valve isn't letting feedwater into the boiler, I'm going to tell you right now that you potentially have a VERY dangerous situation on your hands. Until you get this issue resolved, I would recommend that you not steam this boiler up under any circumstances, unless you have a backup feedwater delivery system that is working correctly. Many people don't know this, but a low water condition in a boiler under steam is essentially a ticking time bomb and can result in a fatal explosion. As to what may be causing it, I would say it's possibly one of two things: 1.) The check valve has been installed backwards and the flow of water is basically pushing it shut. 2.) The check valve is installed correctly, but is frozen shut due to corrosion and scale. Either way, I would have a certified boiler inspector come out and take a look at it; he can probably tell you more than I can.
- Q: My boyfriend just went to his heart doctor and his tricuspid valve is leaking because of his pacemaker wire. They are saying that its moderate to severe. We are trying to decide on what moderate to severe really means. They said the same thing when he was at the doctors in June.
- Tricupsid regurgitation (TR) can be mild, moderate or severe. The tricupsid valve is located on the right side of the heart and separates the right atrium from the right ventricle. During the contraction of the right ventricle, the tricupsid valve is normally closed and does not allow blood to travel backwards into the right atrium. The severity of TR is determined by the amount of blood that regurgitates back into the right atrium instead of going into the pulmonary artery like it normally should. If a small amount of blood is regurgitated, then it is considered mild. If a significant amount of blood is regurgitated then it is considered severe. Moderate is between the two. Cardiologists frequently use the term moderate to severe to indicate that it is somewhere in the middle.
- Q: I'm a 68 year old male. i've had mitral valve regurgitation all my life . recently an echocardiogram listed it as 3 plus. I'm in otherwise good health and continue to jog 3 miles three times a week at about a 9 minute mile rate. Is surgery advised.
- relies upon if there's a click and no indications and the Echo would not point out a leak around the valve you do no longer want therapy. in case you have a click and a murmur and the Echo indictes a significate leak, could lead on directly to shortness of breath and deliver approximately heart failure. will require medicine to capability heart function,if indications do no longer respond to therapy surgical technique in line with risk necessary. Has your Dr ordered a 24 hour Holter computer screen? good luck
- Q: I'm going to replace a valve guide and wondering how I should do it.Should I drill into the existing valve guide to the point it's small enough to pinch with some pliers and pull it out?When I put the new one in, should I use a wooden dowel and an air nailer to pound the guide into place?The more info. the better. It's my first time doing this.Thanks!
- Ohhhh man. NO DRILLS. I assume you are referring to an Aluminum Cylinder head. To do it correctly you need a drift punch that has a pilot size of the valve stem, and an outside diameter that is just a few thousands smaller than the guide. Disassemble the head completely, put in Moms oven at the highest setting it will go to ( 5-6 hundred degrees ) Pound old guide out from the combustion camber side. ( have every thing ready to go this FFer will be hot ). Coat new guide with something like STP, put in freezer, carefully align it, then slam it home from the valve train side, don't pussy around, get it in before it attracts the heat of the head, if you stop or it stops you will have to repeat the entire process. If you gall the Aluminum ( say O-**** ) Since you have to hit this thing fairly hard you will need to refinish the inside of the guide with the appropriate reamer. Then refinsh Valve seat ( they never, NEVER line up perfectly )
- 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
- Hello again. The valve I have implanted in me is porcine. Pig valves are sometimes used for a few reasons. First of all, they are much easier to get a hold of. Waiting for a human valve can take a long time. Secondly, there is less risk of rejection. These two reasons make a porcine valve better than having a human valve. You can also have metal valves, but when you have one or more of these you must take crazy medications for your entire life. With porcine valves, no extra medications are needed. So, porcine valves are really the best option. Like I said in a previous answer to one of your questions, I had my surgery when I was 16. I'm 22 now and doing alright. My valve is expected to last 10-15 years, so I expect to go under the knife to have it replaced when I'm 26-31. Unfortunately I have other issues and will have to have the surgery done earlier, and they'll probably change the valve while they're in there already. As far as I know, porcine valves last just as long as human valves. Whichever you have, it's going to clog up eventually anyways.
