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: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:The valve is rusty and can not be opened. What shall I do?
- Remove the handle and lever the stem rotation with a wrench,
- Q:What are the types of valves?
- 1.1 classification by purpose and functionx09 (1) cut-off valve is mainly used to cut off or switch through the media flow, including gate valve, globe valve, diaphragm valve, ball valve, plug valve, butterfly valve, plunger valve, ball plug valve, needle type instrument valve, etc.x09 (2) control valve is mainly used to regulate the flow of medium, pressure, etc., including regulating valve, throttle valve, pressure reducing valve and so onx09 (3) check valves are used to prevent backflow of media. Check valves with various structures are includedx09 (4) diverter valves are used for separation, distribution, or mixing of media, including distribution valves and traps for various structuresx09 (5) safety valves are used to protect the medium against overpressure. Various types of safety valves are included1.2 classify by main parameters
- Q:There is a rectangular hole in the valve core, which the heating company repairman gives to the bolt. Rest assured, I do not want to heating, but my indoor temperature is low, I suspect that the repairman mischief, deliberately give me lower temperature
- The valve has a device like a cylinder lock that opens with a special key.The heating valve refers only to a radiator system accessories, is a type of valve, the valve commonly used heating system on the market is mainly divided into: gate valve, ball valve, safety valve, balance valve, globe valve, regulator valve, relief valve, pneumatic control valve.
- Q:What do the Z, J, H and D represent in the valve type?
- :Austenitic stainless steel, copper alloy, plastic, rubber, nylon plastics, fluorine plastic, Cr stainless steel, hard alloy, rubber lining, Monel alloy, valve body material
- Q:Where is it installed, what is the role, what is the material, and are there other alternatives instead of this effect?
- Main stem to prevent leakage, there are PTFE and graphite and so on. There are no other good products to replace.
- Q:What's the valve specification DN20?
- You should be asking, how many inches?DN20 is 3/4
- Q:How do you calculate the valve wall thickness, pressure, and other valve design calculations in a spreadsheet?
- For you to introduce the spreadsheet calculation, application basis, you according to this principle for valve correlation calculation:When A1 and B1 cells are used as parameters, the amount of computation is calculated by C1. If the formula is X+Y=? In the A1 cell, fill in the X; fill the Y in the B1 cell; fill in the C1 cell with "=A1+B1"; enter the carriage, and then calculate the corresponding value in the C1 cell. For example: fill in 5 in the A1 cell; fill in 8 in the B1 cell; enter the carriage, and then appear in the C1 cell 13. Other calculations are the same, you will calculate the valve formula, such as the above fill in, given the corresponding parameters, the same can be calculated.
- Q:What are the specifications of the valves PN25, DN50?
- PN is the pressure. DN is caliber. In a nutshell, it's the valve of 25bar 50!
- Q:What does the "PN" mark on the valve mean?
- The valve will usually be marked with "DN.PN." these two signs,DN refers to the valve path, and PN refers to the pressure levelFor example: DN25, PN16Refers to the valve diameter of 25mm valve, the pressure is 16 kg (1.6Mpa)
