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: Which industries need valves?
- Valve application industryValve users in a wide range of industries, can be divided into petroleum, petrochemical, chemical, metallurgy, electricity, water conservancy, urban construction, machinery, coal, food and other. Among them, the machinery and chemical industry users are most concerned about the valve market, and their requirements for the valve is also higher. The largest users of valves are the petrochemical industry, the power sector, the metallurgical sector, the chemical industry and the urban construction sector.Valve application typeIn the application of the types of valves, machinery, metallurgy, petrochemical, chemical, urban construction and other industries, the application of the valve classification of the most. Especially in the machinery industry, all kinds of valves are basically applied. In addition to the mechanical industry, the safety valve is mainly used in chemical industry; butterfly valve is mainly used in petrochemical and metallurgy; diaphragm valve is mainly used in metallurgy, electric power and chemical industry; check valve is mainly used in metallurgy, chemical and petrochemical; valve mainly used in petroleum and chemical industry; the cut-off valve is mainly used in metallurgy, petrochemical, chemical and power sewage; valve is mainly used in petrochemical and chemical industry; the ball valve is mainly used in petroleum, chemical and metallurgy; valve is mainly used in chemical industry, electricity and construction; the valve is mainly used in chemical, metallurgical, power and food; used in petrochemical and metallurgy main plunger valve; plug valves are mainly used in chemical and metallurgical valve; mainly used in petrochemical, chemical and metallurgy; steam traps are mainly used in chemical and petrochemical.
- Q: How to identify the good or bad of the valve, without pressure test and instrument?
- First, the appearance, two according to the standard to see flange thickness, outer circle, wall thickness and other dimensions are standard, 3 see details.
- Q: such as gate valve, three way plug valve
- The lower part of the pressure gauge installed water pipe, there are water, avoid high temperature, medium pressure gauge contact directly cause damage, so regular cleaning, in order to avoid congestion, three way plug function is used for flushing, please see "how to operate them.".
- Q: Hydrant valve leaks, how do you close other valves? Specific steps?
- Crown valve pressFirst, make sure the front of the fire hydrant has a gate valve or butterfly valve Yes, it will be closed and replaced by the lineNo, then useSecond, the pressure of the pipeline to see how big, and if it is rare, replace it with water
- 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 valve does the high pressure by-pass valve DN254 * 800 belong to?
- You want to ask the classification or valve DN254 mean?. The data you gave was incomplete. No answer.
- Q: How does the valve open?
- This is a three pass, not a valve. It doesn't open often or often closes and there is no opening or closing. Can change the same caliber of the valve, you can use the handle switch.
- Q: What are the ten major brands of China's valves?

- Q: What is a hot melt valve?
- The valve is hot melt and ppR/PE plastic pipe connecting with hot melt connection valves, general valves generally use the threaded connection or flange connection.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..
