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

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 does the valve stroke mean?
- The distance from one position to another. Usually in the first position of the cut position, the second position is put through the position. Unless the valve has 3 positions.
- Q: What does "TD671F" mean?
- TD671F is pneumatic clamp type soft sealing butterfly valveValve (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: What is the choice of pneumatic valve or electric valve for ultrafiltration inlet control valve?
- Pneumatic valve compared to the electric valve, the valve can be the same, rubber lined butterfly valve or other valves, pneumatic valve opening speed (Basic 1 second can be fully open), the price is lower than the electric valve. But there must be process air (4-6bar compressed air). According to my experience, if the scene has compressed air, it is recommended to use pneumatic valve, if there is no compressed air, it is recommended to use electric (electric valve expensive, open valve slow).
- Q: Is the filter also valve?
- Filters are generally used in the pipeline, are ancillary products, strictly divided, it does not belong to the valve category
- Q: Which valves are used in the power station?
- Water supply system: butterfly valve, gate valve, eccentric hemisphere valveOil and gas system: stainless steel ball valve, stop valveFire fighting system: gate valve, relief valve, relief valve, sprinkler system
- Q: Where is it installed, what is the role, what is the material, and are there other alternatives instead of this effect?
- Mainly from the role of sealing, to prevent leakage of the valve conveying medium, stuffing commonly used PTFE, graphite, asbestos packing three.
- Q: What's the sewage treatment valve with?
- Butterfly valve manufacturers are many, the price is also different, as long as the right can.
- Q: What is the term "Z41H-16C" on the line?
- When Z41H-16C opens the valve, when the gate lift height is equal to 1:1 times the valve path, the passage of the fluid is completely unblocked, but at run time, this position is not monitored. In actual use, the top of the stem is used as a sign, i.e., the open position, as its fully open position. Temperature changes appear to consider locking phenomenon, usually open to the vertex position, and then rewind 1/2 1 circle, as a fully open valve position.
