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.

 

2.Main Features of the Manual Wafer Butterfly Valve 

a)Cast hole. Flange connection meet ANSI 125/150#   DIN PN10/16   BS4504 PN10/16 in the meanwhile.

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: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:Is the valve galvanized?
If you need it, you can order it. Any valve will do
Q:How big valves are used in the DN90 pipeline?
If you use a 97 tube, the inner diameter of 89- phi 90., nominal pressure is low, then try to use DN80, DN80 valve diameter of 80, you can try butt welding
Q:How to find all kinds of mysterious valves of human body?
Many cell signal channels have been found, and if you can find each signal, the channel will be almost the same. That's the mysterious valve you want, but it's hard.
Q:What are the specifications of the valves PN25, DN50?
Upstairs professional level can be seen very solid.... Clap your hands... Popular speaking, that is, the valve bore is 50, resistance to pressure is below 25, is no problem.
Q:What is the term "Z41H-16C" on the line?
The ram of the Z41H-16C is linear with the stem, called (also known as the bar gate valve). Usually there is a trapezoidal thread on the lifter. The rotating motion is changed into a straight line through the nut at the top of the valve and the guide groove on the valve body. That is to say, the operating torque is changed into the operating thrust.
Q:What are the major brands of valves abroad?
I say a few familiar: Tyco (the world's largest manufacturer of valves, the valve can provide almost all of it) Fuchs (a bit like, with the whole series of Tyco products)Blake (mainly butterfly valve, ball valve, chemical and water treatment applications up)Gaemi (diaphragm valve is doing very well) KSB (mainly in the power industry valve, globe valve, etc.)
Q:What does the "XV" valve mean?
XV:X said V is plug valve, said valve body material is chrome molybdenum vanadium steel.
Q:Symbols for all types of valves
Look at the attachment I gave you. The legend of the valves is complete!
Q:How to carry out the valve strength test and air tightness test?
Refer to the GB/T13927 or ISO5208 standards and need to pass it to you
