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.
b)Soft seat. Replaceable. Increase of service life.
c)Double half shaft without pin.
d) Square and short neck. Easy to stick scutcheon and cost saving.

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:Remove the handle and lever the stem rotation with a wrench,
- Monel alloy is mainly applied to the valve in the medium containing hydrofluoric acid.6, Hastelloy alloy is mainly used in the valve of strong corrosive medium such as dilute sulphuric acid7, titanium alloy is mainly applicable to all kinds of strong corrosive medium valveRecommendations for the GB standard of steel and ASME second A copies at American Standard. For American Standard steel can also see ASME B16.34
- Q:In the decoration, I do not know where to get the valve, what kind of products should be bought?It is hard to fit the valve in the water inlet of the house. If not, can you? Will it have any effect on future use?
- Common valve position is few, 1 or 2 wash basin faucet pipe toilet pool 3 4 water heater 5 water washing machineThese positions require only simple ball valves or globe valves. Gas valves need not be considered, provided by gas installation companies (specific standards).The main valve can achieve the above water source control, the installation of the branch valve is to take into account the maintenance is convenient, does not affect other water.
- Q:How do you calculate the flow of the valve?
- Valve flow calculation value is very vague, pipe pressure, back pressure, medium viscosity, medium temperature, valve structure, and so on, will affect the calculated value.

- Various types of valves, with the continuous improvement of various types of equipment, process, the types of valves are still increasing. But generally speaking, they can be divided into two major groups.(1) automatic valve. A valve that moves by itself depending on the capacity of a medium (liquid, air, steam, etc.). Such as safety valve, pressure reducing valve, check valve, steam trap, air trap, emergency shut-off valve and so on. (2) drive valve. A valve operated by hand, power, hydraulic, or pneumatic. Such as gate valve, globe valve, throttle valve, regulating valve, butterfly valve, ball valve, plug valve and so on.
- Q:What are the advantages and disadvantages of this method? Are there any other ways to adjust the flow rate?
- Adjust the speed of the water pump to adjust the flow of the most appropriate, such as liquid or variable frequency control, with the switch pump outlet door to adjust the flow rate is the most uneconomical.
- 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
- Q:Why can't the clip type check valve be directly connected with the pipe mouth or other valves?
- The clip type check valve is made up of two discs to prevent backflow.If the clip check valve is connected to the other valve, the disc may touch the valve and cause the check valve not to be fully opened or closed. This is a preliminary analysis of "enter the valve", for reference only!
- Q:Where is the Shandong valve? How about joint valves in Shandong?
- Zigong Sichuan power station valve factory is a professional power equipment supporting valve factory, mainly power plant high temperature and high pressure valve, plug valve, ball valve, temperature reduction and pressure relief device
- Q:What valve is the VENT?
- VENT position usually refers to the valve on the leak detection valve, relief valve, but not the same as the use of DRAIN, which is used for sewage.
- Q:What is the purpose of the valve?
- Valve is a pipe accessory. It is a device used to change the direction of the passage and the direction of the medium flow, and to control the flow of the conveying medium.Valves have the following uses:1. Connect or cut off the medium in the pipe. Such as gate valve, globe valve, ball valve, plug valve, diaphragm valve, butterfly valve and so on.2 、 adjust and control the flow and pressure of the medium in the pipeline. Such as throttle, control valve, pressure reducing valve, safety valve, etc..
