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: How about the valve?
Now, there is an office in Beijing, valve enterprises in the valve, a lot of online ah, you click to see if you want information
Q: What is the use of each brand in the super high-rise, commercial complex, hotel? Price comparison of each brand? In the general valve, balance valve, electric valve, who did the best? Any knowledge about the valve, please ~ ~ thank you for your generous with your criticism
Tyco doesn't know much about it. It's often written in the bidding documents, but there are very few actual purchases, so I don't evaluate it any more. The strongest of the balance valves is the TA (Swedish). He was the originator of the balancing valve. Super high-rise complex, the hotel part, you mention these kinds of valves are applied a lot.
Q: Measure the temperature with a thermocouple, and then how to make the valve open when the temperature reaches a certain value. When the temperature is lowered, will the valve be closed?Or tell my brother what is the knowledge, I can see it myself. Good. How much extra?!
You don't know if the precision requirement of high precision can be used for high requirements of valve control valve (4-20mA) control but need converter needs the temperature signal into your current signal control valve (4-20mA) valve door factory will not have this thing you can ask to do control system manufacturers (in tell you part of the valve switch and adjust the price of at least 1000 points (OH) to not give me angry) is something you can ask me the valve factory
Q: Valve connections - two how do different connections work?
The connection of two different connection forms is achieved by a transition conversion connector
Q: the use of natural connections, is strictly prohibited counterparts. What do you mean by "strong opposition"?
Refers to the installation of the interface dislocation, misalignment or installation of the wrong size and forced connection, resulting in installation stress exists, in use, it is prone to abnormal damage.
Q: What is a heavy body valve?
You should be asking what a heavy-duty valve is.This is only in the ordinary gate valve and cut-off valve on the distinction. Nowadays, ordinary gate valves and cut-off valves are divided into heavy-duty ones. Medium and light three kinds ~!
Q: What is the difference between a stop valve (a power station valve) and other valves?
Power station cutoff valve advantages editor1., the fluid resistance is small, and the coefficient of resistance is the same length as the pipe section.2., simple structure, small size, light weight.3., reliable and reliable, the current gate valve sealing surface materials widely used plastic, good sealing, vacuum system has also been widely used.4 easy operation, open and close rapidly, from fully open to fully closed as long as 90 degree rotation, facilitate remote control.5., easy maintenance, simple valve structure, sealing ring is generally active, disassembly and replacement are more convenient.6. in full open or full closed, the ball and valve seat sealing surface and dielectric isolation, the media through, it will not cause erosion of the valve sealing surface.7., a wide range of applications, from small diameter to a few millimeters, large to several meters, from high vacuum, high pressure can be applied.
Q: Why is the valve on the pipeline not the same size as the pipe, and how much of a crude pipe can be given? Thank youI'm sorry, I didn't make it clear that when doing pipe work in the factory, for example, 60 of the pipe, and in this pipeline to install the valve to choose DN50, and so on.
Do you mean the form of welding? The size of the valve can be changed according to the size of the pipe!
Q: What is the term "Z41H-16C" on the line?
When Z41H-16C opens the valve, when the gate lift height is equal to 1:1 times the valve path, the passage of the fluid is completely unblocked, but at run time, this position is not monitored. In actual use, the top of the stem is used as a sign, i.e., the open position, as its fully open position. Temperature changes appear to consider locking phenomenon, usually open to the vertex position, and then rewind 1/2 1 circle, as a fully open valve position.
Q: Yongde jiekelong valves and valves of the good faith
Fujian Xiamen huashenghong Sanitary drainage fittings. Furniture guide rail, hardware, Taiwan locomotive. All of the above are the strongest domestic brands, high quality, stable performance, durable, buy a lifetime warranty, quality products. Domestic airport, water cube, bird's nest are using the above brand accessories.
