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 main function of the valve?
- 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..
- Q:I'm going to put a solar energy and an electric water heater installed in the same hot water pipe, a valve, a valve open and close the valve B and vice versa the installation of solar and electric water heater, there can be no linkage valve?
- In industry, you say this, such as using two butterfly linkage and composition of the three-way valve to use. But civilian should be few, demand is very little ah. It is estimated that you can only install two valves and then use both hands at the same time to perform linkage.
- 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.
- Q:What valve does the high pressure by-pass valve DN254 * 800 belong to?
- This is because the bypass valve is a special valve and other valve type theory.This is custom-made valves, generally no inventory, and may not have the material you need. So it needs to be customized.I remember the German HORA had the valve, but the price was sky high.
- Q:Tell me the exact address, or the phone number in the market. Where is the industrial zone (the valve) in Hefei? Please help, thank you
- Hardware city inside, on the opposite side of the East Second Ring Guoqiang steel market
- Q:How can you replace the other valve when the main valve is not closed and no water is stopped?
- Not recommended against the flood to repair the valve, first you have to be repaired, second may be more complex, it is not easy. I have a bad experience this, take the valve, because it is plastic, and aging, the thread is broken, the new is not on do not have to flow out of the water, get it is. To find the valve, the mess!
- Q:How does the valve open?
- Now the valve is in a closed state, the general valve on the valve flow direction marked, like you figure on this, flat side perpendicular to the flow channel is closed, parallel to the flow channel is open.
- Q:Which valve can play a good regulatory role?
- A wide range of valves, the function is different, although like conventional butterfly valve, ball valve can play a regulatory role, but their role is not linear, so if you need to adjust the precision of the valve, it is best to select the control valve.
- 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
- It is loaded against the supply and return water pipe is not underground do in next time if it is to see if there is any water on the side of the baffle remember from the baffle recently if it is normal that is motivated next must put off the baffle
- Q:Valve connections - two how do different connections work?
- The connection of two different connection forms is achieved by a transition conversion connector
