Q:It is different from the butterfly valve butterfly valve
How it works: the disc is driven by the stem, and if it turns 90 degrees, it can be opened and closed once. By changing the deflection angle of the plate, the flow of the medium can be controlled. The main sealing element is a sealing ring, and the material is selected according to the use and the medium.
Q:The difference between the directly buried gate and the flange valve and butterfly valve
Buried gate also called buried gate valve, valve can be directly buried underground, built without manhole, reduce road excavation area; small well maintained road and beautiful room can reduce the difficulty of construction, reduce project cost. The directly buried soft sealing gate valve is divided into two types: telescopic type and fine fixing type, wherein, the telescopic type is divided into metal type and plastic type. In the process of construction, the telescopic type can be adjusted arbitrarily according to the distance between the buried depth of the valve and the ground, and the micro adjustment can be adjusted on the spot. The directly buried gate valve has the advantages of long-term use, no leakage, no maintenance, etc., and can effectively avoid other people switching the valve and stealing the manhole cover at will.Flange gate valve is connected to the flange gate valve, this connection is the most common way.
Q:Which is expensive, butterfly valve?
Gate valve and butterfly valve can not simply take the price there to compare, look at the actual design requirements of the project. General small caliber are selected by the valve, because of better sealing performance, service life is long, the maximum diameter of valve is usually choose to use the butterfly valve to the pipeline DN800800 above, because the valve is cheap, the price is only half of the large diameter valve. Also some pipes from the use of quality point of view, will choose the gate valve. How to use it, please mark the map
Q:Im replacing the valve stem seals from my 1991 jaguar xj6 and the valve dropped?
Asking okorder.com/
Q:how to get a valve out of combustion chamber?
The valve head is larger then the valve port, so it's not coming out of there. Pull the head.
Q:What are the major disadvantages of butterfly valves?
Rubber elastomer in the butterfly valve will cause tear, wear, aging, perforation and even shedding in continuous use. The traditional heat curing process is difficult to adapt to the needs of on-site repair. It is time-consuming and laborious to use special equipment when repairing, and it consumes a lot of heat and electricity. Nowadays, polymer composite method is gradually used instead of traditional method.
Q:anti siphon valve?
as you stated, you said the directions said at least 6 from the highest sprinkler 7 will be ok as well as 20. i don't know what region you are in, but if you are in a freeze zone though it is always a good idea to blow the lines when winter comes around.
Q:Electric butterfly valve (not take the lead) what do you mean?
Electric butterfly valve, as its name implies, consists of an electric actuator and butterfly valve, and the customer does not take the lead, that is, without the electric actuator, only the butterfly valve can be provided.
Q:Butterfly valve D41W-1, 41, W, 1, respectively, what does that mean?
D--- stands for butterfly valves; 4--- refers to the form of flange connections; 1--- refers to the valve stem and disc in the center of the valve line, without eccentricity; w--- refers to the valve seat material and body material is the same, usually carbon steel. The final 1--- refers to the nominal pressure of 1 kg / cm2.
Q:Valve cover gasket replacement?
The gasket set is probably $ 20, so double that to $ 40..... 270 - 40 is 230, divided by 2 man-hours, which is the usually dealership minimum, gives $ 115 an hour. I DON'T THINK SO !!!! Unless you live in Hawaii where everything is expensive, that sounds steep.... real steep. Dealers around here get like $ 85 an hour, so two hours is 170, plus 40 is 210 bucks; Still killer money for the dealer..... I'd question that estimate ask if there is some extraordinary challenge to working on your car. It is possible there are accessories mounted over the valve cover that will have to be moved, or that's it's a canted V-6 with one valve cover tucked up against the fire wall. Be nice, smile, ask questions.... Maybe even have someone show you what has to be moved on your engine to get at the valve cover(s). If you're going to pay that much $$$, you should learn something, also.
