1. Manual Wafer Butterfly Valve Description

A butterfly valve is a valve which can be used for isolating or regulating flow. The closing mechanism takes the form of a disk. Operation is similar to that of a ball valve, which allows for quick shut off. Butterfly valves are generally favored because they are lower in cost to other valve designs as well as being lighter in weight, meaning less support is required. The disc is positioned in the center of the pipe, passing through the disc is a rod connected to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc is always present within the flow, therefore a pressure drop is always induced in the flow, regardless of valve position.

5.FAQ

 

1. What is manual wafer butterfly valve?

A: Wafer style is the more common of the two and is less expensive than the lug style. The wafer style butterfly valve is just about the standard. It ís so common that no one even bothers to use the word "wafer" when ordering a butterfly valve. It is taken for granted that if a butterfly valve is ordered, a wafer style will be received.

 

2. How about the Installation of the Wafer Style Butterfly Valve?
A: Butterfly valves are installed by inserting the valve between two flanges using bolts or studs and nuts to hold it all together. This type of installation, of course, makes it impossible to disconnect just one side of the piping system from the valve. That benefit is received using the lug style valve.

 

3. What is the working principle of manual wafer butterfly valve?

 A: A butterfly valve is from a family of valves called quarter-turn valves. In operation, the valve is fully open or closed when the disc is rotated a quarter turn. The "butterfly" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is fully open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the fluid. The valve may also be opened incrementally to throttle flow.

 

Q:What does valve 41F-40C mean?
Incomplete model4 is the flange1 is the formF is seat material, fluoroplastic, ptfe,40 nominal pressure 40 kgC body material carbon steelFront also have to add valve category code, such as manual ball valve, Q41F-40C manual code is 0, but this 0 we don't write out, so only written Q41F-40C electric ball valve, Q941F-40C 9 represents electricGate valve is Z41F-40C
Q:I used to do pumps, and now feel the future of the valve better, looking for a valve to do proxy, but my own economic strength is not good, I do not know if there is no possible to do?
As the two floor said, looking for agents depends on your targeted customer base is better sign is the price of comparative advantage of the brand. Now the valve on the market in Fujian, Wenzhou. Especially, these valves are faced with the market price, the quality of course needless to say. Maybe these valves would sell large the early recovery of funds, is also rich. But for a long time, the problem appeared, quality problems will make you sleepy fishing, I suggest you. You can't do anything sales quality and good reputation of the valve.In the few I know better. Now the best reputation is Guanlong, but the price comparative advantage or spring.
Q:What does "1/2" mean on the valve?
1/2 on the valve indicates that the ends of the valve are 1/2 inches in diameter.Valve is a control component in the fluid delivery system. It has the functions of closing, adjusting, guiding, preventing reverse flow, stabilizing voltage, shunting or overflow and releasing pressure.Valves used in fluid control systems, from the simplest stop valve to a very complex automatic control system used in a variety of valves, a wide range of varieties and specifications. Valves can be used to control air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow. The valve according to the material is divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316), chrome molybdenum steel, chromium molybdenum vanadium steel valves, valve, dual phase steel valves, plastic valves, non-standard customized valve material etc..
Q:Valve difference
Valve difference, or you should ask the classification of valves, valve classification, there are several sub methods, some according to the model, and some are by use, then each kind of valve is divided into several categories and models. Take the trap for example, it is a kind of valve, and then it is divided into steam traps, air traps, float traps, and so on. If you really want to know the difference between the valve you search the Internet under the classification of the valve, there are a lot of articles, or you directly to the trap inside www.ssfmsh find an article on the valve type article, can not give you a specific address, is not allowed here. You work hard, go find kazakhstan. I hope my answer will be helpful to you.
Q:someone else's home has valves, but also checked nothing, in addition to telephone repair, there are other ways? emergency
Get some water with your neighbors first, property. That's a lie. Other people's homes do not necessarily have water.You need to keep on pressing the property.You should live in a high-rise, if there is no power failure, that is, the water tank pump failure, and urge property repair is.I hope I can help you
Q:Hydrant valve leaks, how do you close other valves? Specific steps?
Hello my name is Baidu know the long days of high water leakIn the vicinity of a common fire hydrant, there is a valve, which is convenient for fire hydrant maintenance, because fire hydrant repairs need to close the water source. Look around, it should be easy to find the valve. Switch valve is very simple, and the direction of the twist screw is the same, clockwise turn off, counterclockwise is open. Closed valve, fire hydrant will not leak, you can feel relieved to repair. I guess your fire hydrant is sealed rubber pad, aging causes leakage, it is a common disease of fire hydrants.
Q:Which valves are used in the power station?
Power gate valve, also known as power station valve, is mainly used in various pipelines of fire power plants, cutting off or connecting pipeline medium.Applicable medium: non corrosive media such as water and steam. Compared with other valve products, the valve is characterized by high temperature and high pressure and unique self sealing design. The higher the pressure, the more reliable the seal is. Because of its performance, technical characteristics and special working conditions, the products can not be replaced by other products.Compared with other valve products, the gate valve of the power station is characterized by high temperature and high pressure. If only the pressure is lower than that of the universal valve, the temperature is lower than that of the general valve. Because of its performance, technical characteristics and special working conditions, the products can not be replaced by other products.
Q:Which valve can play a good regulatory role?
A wide range of valves, the function is different, although like conventional butterfly valve, ball valve can play a regulatory role, but their role is not linear, so if you need to adjust the precision of the valve, it is best to select the control valve.
Q:What are the most common types of valves?
Gate valve, globe valve, check valve, ball valve, butterfly valve, safety valve, drain valve, plug valve, throttle valve, plunger valve, diaphragm valve, relief valve, foot valve, drain valve etc.
Q:What does the whole copper valve mean?
The whole valve is made of copper material. In addition to the ceramic core.
