Q: Butterfly valve D41W-1, 41, W, 1, respectively, what does that mean?: This butterfly valve in our factory called butterfly, 4 represents the connection of the flange connection flange is French, 41 in 1 on behalf of butterfly valve, W represents the body seal, is C that is actually the correct type of cast steel, should be D41W-1C. Suitable for ventilation, smoke, and these media.

Q: I got my timing belt done on a 1999 Civic Si on September 26 @ 113,699 miles. at 116,9xx miles I bent a valve on my third cylinder. How likely is it that the timing belt is the reason why this happened? I heard that if the timing belt is a tooth or so off, it could bend a valve. So is it likely that this could have happened? Anyway to check?: If it was a timing belt issue it woudn't have only been one cylinder. And usually if it's only off by one tooth, it just runs poorly. IT has to be off by quite a bit, or the belt has to straight up break to bend a valve,, if that happened it would have made a horrible clanging noise repeatedly before it eventually sputtered out. the 1999 Si revs to what... 8000 rpms? You didn't happen to miss a shift and over-rev the engine, did you?

Q: What's the difference between a butterfly valve and an eccentric butterfly valve? What is the difference in field applications?: Eccentric butterfly valve and ordinary butterfly valve, when the butterfly valve is opened, the eccentric butterfly valve sealing surface will reduce great wear, in the opening, the disc will leave the valve at the first time the sealing surface!

Q: 1st where is my zone valve? I have an old Burnham gas baseboard heater2nd What do I do?My last resort is calling a proffesional.: You may have only one circulate pump on the boiler. If you want to check the zone valve there is a small handle on the valve you can lift up and this will open the valve manually. It will be found on the (usually) green valve on the return end of the copper pipe. It should have a red and white wire attached. If this is opened manually and you get heat you can replace the top half of the valve by twisting it off and exchanging it with a new one. I think they are around $35.00 bucks or so at Home depot. You can keep it open without and fear. This means you will only have a one zone boiler and all baseboard s will get heat instaed of being zoned

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.Butterfly valve refers to the closure of parts (butterfly plate) as the disk, around the valve shaft to achieve rotation and closing of a valve, the main cut off on the pipe and throttling role. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation. Butterfly valve is fully open to fully closed is usually 90 degrees butterfly simple structure, small volume and light weight, only by a few parts. Moreover, the utility model can be rapidly opened and closed only by rotating 90 DEG, and the operation is simple.Is the gate valve opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle. Gate has two sealing surface, gate valve advantages: fluid resistance is small, opening and closing more effort, medium flow unrestricted, not disturbing flow, do not reduce pressure.

Q: What does the triplex of pneumatic butterfly valve mean?: Upstairs is quite right, but now seems to use very little oil mist, and now generally referred to as "triple parts" as if: filter pressure reducing valve, solenoid valve, with the valve position feedback switch.

Q: The difference between gate valve and butterfly valve, as well as cut-off valve, what are their applicable conditions? Advantages and disadvantages?: Without strict conditions and advantages and disadvantages, of course, the equipment requires a relatively high degree of automatic control. I can check it out on Baidu.

Q: Who can give me a download UG butterfly valve, needle valve, diaphragm valve standard model address, Japanese standard, American Standard.: Give you the address bar, this is a three-dimensional CAD model library of an online version of the real registered mail, free of charge, there are hundreds of Chinese and foreign manufacturers of the product model is available for download, such as ABB, SMC, FESTO, AIRTAC, CAMOZZI, MISUMI etc..

Q: Who was the first doctor to discover Pulmonary Valve Stenosis? Also, who was the first doctor to perform surgery for it? Please and thank you for your help.P.S. I have this condition.: 1761 - Pulmonary valvar or valvular stenosis is one of the more common forms of congenital heart malformations and it has been extensively studied since the original description of pulmonary valve stenosis by John Baptist Morgagni in 1761. 1888 - Tetralogy of Fallot, first characterized by Dr.Etienne Fallot in 1888, is present in about 3000 children born each year in the United States. It is a combination of four heart abnormalities. Dodrill and his colleagues employed it with success for the open correction of a stenotic pulmonary valve in October 1952.
