- Q: What's the difference between the three eccentric butterfly valve and the two eccentric butterfly valve?
- The structure features that the center of the stem deviates from the center of the disc as well as the center of the body. The effect of the double eccentric valve can be opened immediately after the disc from the valve seat, substantially eliminating the unnecessary disc and valve seat over squeezing, scratching phenomenon, reduce the resistance from the open, reducing the wear and improve seat life. Three eccentric butterfly valve: to high temperature, must use hard seal, but the leakage is large; to zero leakage, must use soft sealing, but not high temperature. In order to overcome the double eccentric butterfly valve this contradiction, and the butterfly valve for third times eccentric. The so-called third eccentric, that is, the shape of the sealing pair is not a positive cone, but rather oblique cone.
- Q: i have a slightly small mitral valve leak in my heart. my cardiologist say nothing to worry about, but i am not sure. can some one explain if it would eventually lead to some complications?
- I have Mitral Valve Prolapse, and slight regurgitation. If your cardiologist says not to worry, I wouldn't worry. Mitral Valve prolapse just means you have a slight deformity of the bicuspid valve. It doesn't close correctly. It's not a disease, or anything like that, just a slight deformity. The symptoms are annoying. You may or may not have palpitations, slight sharp chest pain sometimes, dizziness, fatigue, and anxiety from it. You must have it checked yearly to make sure it's not progressing. I have had it since I was born, and now I am 28, and it has not progressed at all. MILLIONS of people are walking around with it, and don't even know it. It's not really a big deal. However, it does have the potential to worsen and you may or may not need a new valve. But that normally happens when you're older, in your 50's or up. Don't worry about it.
- Q: The difference between butterfly valve d71x_10s and d341s-10
- Before distinguishing between the two, you must first read the identification of the valve type:D stands for butterfly valves,3 means that the worm gear is connected and the drive does not indicate the handle7 and 4 indicate pipe to clamp connection, pipe flange connection, respectively1 means single eccentric, that is, the stem is not in the center of the butterfly plateThe former S indicates the material name of the valve body - plastic, X means sealing and the lining material is rubberThe latter S indicates the sealing lining material code ---- plastic, and the valve body is cast iron.10 means stress.
- Q: I have 1993 Seville 4.9. I got a new EGR valve but it didn't help. I tested it with vacuum pump, it won't hold pressure at all, same with old one. Is that new EGR valve bad or just different type of EGR that vacuum pump won't work? Thanks!
- The first source, pages 20-22, lists all 9 basic types of EGR valves. Not all the types are vacuum operated, but check out #5 and #6 - they behave very differently from each other without a real live exhaust system connected to them.
- Q: Gate valve and butterfly valve which is installed when there is a direction?
- Do not require frequent opening and closing, and keep gate fully open or fully closed. Not suitable for use as a regulator or throttling.
- Q: What are the classification criteria for pneumatic butterfly valves?
- The pneumatic clamp butterfly valve has a novel structure, and the structure of the valve body is short clamp structure for meeting the narrow space of the pipeline, and the outer zero leakage is in place, and the internal leakage conforms to the national standard.Pneumatic butterfly valve, connection flanges, the sealing clamp, lined with NBR, EPDM rubber, heat resistant ethylene propylene rubber, natural rubber, chloroprene rubber, fluorine rubber, PTFE, medium according to the chemical properties have a more rational choice.Pneumatic fluorine valve, corrosion fluorine valve using the bisection valve combination two, valve seat and valve liner valve work, integration, only full plastic seat and lining plastic disc contact with the media, the product can withstand any corrosion in molten alkali metal and fluorine elements ", which D71F46 stem and disc board (forging) as a whole, the surface is uniformly coated with a layer of FEP.
- Q: Butterfly valve switch direction respectively?
- First, if the butterfly valve has been installed on the pipe, you can first see the mark on the handwheel. Second, there is a switch indicator on the general worm gear.
- Q: valve adjustment 2001 chev prism 1.8L
- valve adjustment . you need to know the fire order. the gage between the stem. rotators the cranshaft. it could be cold start. cylinder need to be bottomed center.
- Q: What does "D41X-16" mean?
- There are many kinds of valves, so each valve has a specific model. Butterfly valve D41X-16 code D refers to the butterfly valve, 4 refers to the connection form is flange, 1 refers to the drive mode is manual, X is the valve sealing ring material is rubber, 16 refers to pressure, 16 kg. Valve model is composed of seven elements: valve type, connection form, drive mode, structure, sealing ring material, nominal pressure, material. You can ask me if you don't understand. Dual valve []
- Q: I have a good set of #142 Pontiac heads with small diameter valves. I want to have the heads enlarged to accept the larger Pontiac valves, and I have the larger exhaust valves out of #13 heads and the larger intakes from 6X8 heads. The valves appear ok and shiny on the stems
- Roll the valves by the stems on a perfectly flat table. If there is no wobble, your valves are most likely not bent. Take them to a machine shop and have them checked for imperfections and reground and they'll be good as new.
