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: What is the normal temperature on the valve?
- At normal temperatures are below 120 degrees. A lot of valve sealing surface can only reach 120 degrees
- Q: I would like to ask this valve (not too clear, is it possible to call the valve), what is the specific name of the professional? Where can I buy it?
- I think it's the filter. The valve unit you know, you know, or Baidu. Then contact.
- Q: Valve category can fill the trunk door, branch valve Mody?
- Each of these types of valves have very different varieties, such as the valve can be divided into: self sealing valve, knife gate valve, gate valve, cryogenic insulation jacket valve, seal valve, vacuum valve, flexible valve seat seal, valve, gate valve, signal buried forged steel gate, cast iron gate valve and so on.
- Q: What is the choice of pneumatic valve or electric valve for ultrafiltration inlet control valve?
- Now the UF system is basically full automatic system, that is to choose automatic valve. As for the pneumatic valve or electric valve, depending on your investment and the scene.
- Q: A kitchen, 2 bathrooms, in addition to the toilet, toilet (only cold water), the rest need hot and cold water supply, and hot water by solar water heaters and gas water heater selection. The kitchen is mainly a sink, each toilet for toilet, shower, washbasin, separate cold water faucet. I don't know how many metal materials I'll use now Thank youThe waterways are all dark!
- Generally, a toilet needs 5-6 triangle valves, namely: 1 under the toilet, 2 on the shower, 1 water inlet, 2 under the sink, and two in the kitchen sink.
- Q: Symbols for all types of valves
- Look at the attachment I gave you. The legend of the valves is complete!
- Q: If the valve in the pipeline throttle, such as open and open 50%, the valve before and after the pressure of how to calculate, how the flow changes?
- The valve according to feature points, can be divided into isolation, cut off, check, overflow and regulation, which belongs to the regulation is more complex, such as for a compressible medium, constant flow regulating valve after the pressure is more and more big, natural gas pipelines are now part of the regulating valve the self,
- Q: What are mine valves?
- You want to see what works on the use of what media, in the choice of what type of valve is more appropriate. Shanghai HuquanValve manufacturers, veteran enterprises, trustworthy.
- Q: What are the key valve enterprises in China? Mainly in those areas?
- This does not say, as if no one statistics! But you can check them on some big valve platforms, and there should be some statistics...
- Q: How are the types of valves classified?
- 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.classificationFunction and use(1) cut off categories: such as gate valve, globe valve, plug valve, ball valve, butterfly valve, needle valve, diaphragm valve and so on. Cut off valve, also known as closed-circuit valve, stop valve, whose role is to connect or cut off the pipeline medium.Check valves, also known as check valves or non-return valves, check valves belong to an automatic valve, its role is to prevent the pipeline medium backflow, to prevent the pump and drive motor reversal, as well as the leakage of container media. Pump water off the bottom valve check valve also belongs to class.The function of the relief valve is to prevent the medium pressure in the pipeline or device from exceeding the required value so as to achieve the purpose of safety protection.Control valve, throttle valve and pressure reducing valve, its role is to regulate the media pressure, flow and other parameters.(2) vacuum type: such as vacuum ball valve, vacuum flapper valve, vacuum air charging valve, pneumatic vacuum valve, etc.. Its function is to change the direction of the air flow in the vacuum system, adjust the air flow rate, cut off or connect the vacuum system of the pipeline, and the component is called the vacuum valve.(3) special uses such as pigging valves, vent valves, drain valves, exhaust valves, filters, etc.. The exhaust valve is an essential auxiliary component in the pipeline system. It is widely used in boilers, air conditioners, petroleum, natural gas, water supply and drainage pipelines. Often installed in the commanding heights or elbows, etc., to exclude excess gas pipeline, pipe road to improve the use of efficiency and reduce energy consumption.
