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: 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's the meaning of the "single valve"?
- Make is commonly known as "living joint". The utility model is a common pipe connecting piece which can be conveniently installed and disassembled.
- Q: High and low pressure valve is how to distinguish?
- Vacuum valve - valve with operating pressure below standard atmospheric pressure.Low pressure valve - nominal pressure PN is less than 1.6MPa valve.Medium pressure valve - nominal pressure PN 2.5~6.4MPa valve.High pressure valve - nominal pressure PN10.0~80.0MPa valve.Ultra high pressure valve - nominal pressure PN greater than 100MPa valve.
- Q: I would like to ask how the valve entry, for a new pair, really difficult, what cutaway view, there are other, just contact the valve less than a week, and sometimes it is really difficult to understand. Forget the experienced teacher can be generous with your criticism to later, indebted forever, learn the valve Comrades some help.In a company CAD to relatives as soon as possible to a company, and then slowly improve, I do not know what is the request of the novice, and how to start as soon as possible, I am learning routine is: give me a set of valve design drawings, and then I paint it on, do not understand the structure and workshop look. I wonder if you have any good learning methods that can be referred to and supplemented by younger brother
- I was about 08 years of contact valve, indeed many, but a company, all products will not have, are designed to do certain types of valves, such as for HVAC, or petrochemical, some other valves used in engineering, will do the purchase, so you only according to the company's products study on the line, need to learn what, what, high efficiency.If you do the design, you have to learn a lot of things: "mechanical design manual" and "valve design manual" is essential, often used;Of course, functional things are the basis, that is, the structure, the work principle must be obtained first, in order to do relevant design and improvement;First of all, the structure design, CAD must learn, three-dimensional software also have to learn one, Solidworks, Peo/E, UG, Catia can be;Second, strength analysis is necessary, so in mathematics, mechanics, mechanical design things to learn solid; can make strength analysis with finite element analysis software, need to learn, software Comosworks, Ansys;Third, the valve design will have fluid aspects, flow design, flow capacity, flow characteristics of the study, to study fluid mechanics, heat transfer, etc., CFD software has Fluent, Ansys, CFX, Star-CD;In addition, materials and technical aspects should be learned.Slowly, I also step by step by side with coming.Hope to be of help to you.
- Q: What does valve DN50/80 mean?
- Hello landlord DN50 valve refers to the valve diameter of 50mm DN80 is 80mm if the valve is opening and closing function, so the valve diameter should be and pipeline with the diameter or smaller number, large waste, butterfly valve to be stuck in the flange, the influence of flow.If the role of the valve is adjusted, and that caliber will be different from the pipe diameter, this is not to reduce the cost of the problem, is a result of calculation, and this calculation results with flow, pressure drop and valve resistance curve.For example, control valve, usually smaller than the pipe diameter, such as pressure reducing valve, will be smaller than the pipe diameter to two, such as 57mm pipe with DN50.
- Q: Valve pressure grade division
- Valves are classified by pressure:Vacuum valve - valve with operating pressure below standard atmospheric pressure.Low pressure valve - nominal pressure PN is less than 1.6MPa valve.Medium pressure valve - nominal pressure PN 2.5~6.4MPa valve.High pressure valve - nominal pressure PN10.0~80.0MPa valve.Ultra high pressure valve - nominal pressure PN greater than 100MPa valve.
- Q: How to open the gas valve with drawings
- First of all, you have to determine the direction of the valve opening, usually homeopathy, it is off, the reverse is open. First: to determine the opening of the valve, are generally ball valve, screw 90 degrees on it. Second. At the top of your house, there is a button that can be pulled out.
- 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 is the KVS in the valve parameter?
- KVS meaning in valve parameters:Kvs is the coefficient of flow (also called circulation capacity).Kvs refers to both ends of the valve pressure difference of 0.1MPa, water density of 1g/cm^3, when the valve fully open flow. It is an important parameter of the control valve, reflecting the capacity of the control valve.Flow coefficient is a unit of time, in the test conditions, the pipeline to maintain a constant pressure, pipe flow through the valve mass flow, or mass flow. That is, the maximum flow capacity of the valve. The greater the value of the flow system, the smaller the pressure loss when the fluid passes through the valve. The CV value of the valve shall be determined by test and calculation.
- 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.
