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.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. A butterfly valve consists of body ,stem ,disc , actuator (manual actuator, worm-gear actuator , aerodynamic actuator or electric actuator) , and wafer type butterfly valve can implement the process for turning on turning off and regulating the flow by the circumrotation of stem and disc that is droved by actuators.

5.FAQ
1. 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.
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.
- Q:How to connect the signal butterfly valve?
- If you mean the signal of fire water supply system, there are generally three outlets, one public, one open and one off. Fire control system signal butterfly valve is normally open, so the signal butterfly valve to open position, with a multimeter to measure the 2 lines, the 2 lines into the input module is fine.
- Q:Butterfly valve structure and working principle
- The clip type butterfly valve is connected with the two pipe flange with a stud bolt. The flange type butterfly valve is provided with a flange on the valve, and bolts are used to connect the flanges at the ends of the valve to the pipe flange.
- Q:Three eccentric hard sealing butterfly valve, why not fit in the end of the pipe?
- Three eccentric hard seal butterfly valve quality standards, up to zero leakage, but you mean the end of the direct discharge?If so, that's OK. First you have to calculate how much the pipe fluid pressure is.For example, the pipe fluid pressure is highest and the pressure is 1.6MPa (16 kg)Should choose three eccentric hard seal butterfly valve should be pressure 1.6MPa (16 kg)If you worry, optional 2.5MPa (25 kg) will not leak!Answer: three eccentric hard sealing butterfly valve can be installed at the end of the pipe
- Q:The flow ratio of area and maximum flow area of the valve is? If it refers to the opening of the valve rotation angle? Butterfly linear closure refers to the butterfly valve at constant angular velocity close? When the change trend of flow is what? These valves problem bothering me for a long time,
- Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis rotation, so as to achieve the opening or closing or adjustment; actuators have electric or pneumatic, and so on, through the transmission device to drive the stem, valve plate rotation;
- Q:CAD drawing of butterfly valve
- Your question is very international. Ha-haThis method of painting is not clear in one or two words.First you'll know the map, then you'll use CAD, so the two will add up.Guess you will.
- Q:butterfly valves d7a1x5
- D71x-1.6? Or D371X-1.6, do you need butterfly valves for production or butterfly valves? The question perplexed us all.
- Q:When will Butterfly Valves be used?
- 3, there are anti-corrosion requirements of the pipeline, such as sewage, chemicals, etc.;4 、 pipes that regulate flow control requirements, such as quantitative systems;5, there are open and close, fast opening and closing requirements of the protection of the pipeline system, rapid cutting......

- Q:What's the difference between cut-off valve, gate valve and butterfly valve? What's the difference in the working principle?
- Gate valve, also known as gate valve, is a widely used valve. Its closing principle is that the gate sealing surface and the valve seat sealing surface are smooth and smooth, and they fit together to prevent the flow of the medium, and rely on the die shape of the top die, spring or gate to enhance the sealing effect. It mainly cuts off in the pipeline. The cut-off valve, also called the door, is the most widely used as a valve, it is popular is because the process of opening and closing the sealing surface friction between the small, more durable, highly open small, easy manufacture, convenient maintenance, not only for low pressure, but also suitable for high pressure. Butterfly valve with light characteristics, more than other valves to save material, simple structure, quick opening and closing, cutting and throttling can be used, the fluid resistance is small, labor-saving operation. Butterfly valve can be made into large caliber. Where you can use the butterfly valve, it is best not to make the gate valve, because the valve is more economical than the gate valve, and the regulation is good. At present, butterfly valves are widely used in hot water pipelines.
- Q:What is the difference between turbine butterfly valve and flanged butterfly valve?
- Their models are different, the structure is different, they are the main driving part, different worm gear and straight rod distinguish, all belong to the flange valve.
