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: the rest are hot, the living room outside all the heating pipe valve closed, the living room heating is still not hot, after the water for a while hot, and cold
- You just put the living room off the water inlet valve, open the drainage valve with backwater top a try
- Q: What does the "XV" valve mean?
- XV if in front of the valve position, such as XV2211-011, then the XV indicates the switch valve, which is a representation of the Control Valve relative to the regulating valve.
- 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: What is the main function of the valve?
- Valve (Famen) 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: How to quickly identify the types of valves?
- The "Practical Handbook" valve design on the valve structure, with precision, surface roughness and typical design standard, the valve has hundreds of models, and continue to have a new valve, see a written one, is shorthand.Valves: valves (Valve) control the flow of fluid medium flow, flow, pressure, temperature and other mechanical devices, valves are the basic components of the pipe system. Valve fittings are technically similar to pumps and are often discussed as a separate category. Valves can be operated by hand or hand wheel, handle or pedal, or by control to change the pressure, temperature and flow change of fluid medium. The valve can perform continuous or repeated operations on these changes, such as a safety valve installed in a hot water or steam boiler. In more complex control systems, automatic control valves are required depending on external inputs (i.e., regulating the flow through the pipe to the changing setting points). Automatic control valve without manual operation, according to its input and settings, so that the valve accurately control the requirements of fluid medium. The valve according to the material is divided into cast iron valves, cast steel valves, stainless steel valves, chrome molybdenum steel, chromium molybdenum vanadium steel valves, valve, dual phase steel valves, plastic valves, non-standard customized valve material etc..
- Q: Is there any problem with connecting the geothermal valves with other geothermal pipes?
- Yes, as long as it's all PPR's.Material is the same, the fuse will not cause shrinkage when you can use
- Q: How do you calculate the valve wall thickness, pressure, and other valve design calculations in a spreadsheet?
- The valve wall thickness is the standard valve check directly in the relevant standard, for insert grade valves need to use interpolation method to calculate the valve wall thickness, actually don't need what difficult to complete in EXCEL software.
- Q: Where is the valve used?
- Oil and gas pipelines, gas stations, gas stations, petrochemical plants, water works,
- Q: What does the valve QF mean?
- Valve type, one of the contents, Q refers to the ball valve, F refers to the F-4 seals.
- Q: What are the key valve enterprises in China? Mainly in those areas?
- The region, the largest number of Wenzhou. Focus on the valve business, Zhongyuan District Kaifeng high pressure valve factory, Zhengzhou Zheng butterfly valve on behalf of the butterfly valve. Shanghai region, Tianjin, northwest Lanzhou high pressure, Suzhou area, northeast Tieling region, Dalian, Shenyang and so on. And the Zigong area
