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.

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 are the valve types H, F, and Y? What are the meanings of these 3 letters?
Please refer to "JB/T308-2004 valve model preparation method"Sealing surface material codeH Cr13 stainless steelF fluoroplasticY cemented carbide
Q:Which valves are installed in a directional manner?
Depends on the specific valve is one-way seal or two-way seal?
Q:What is the valve?
Is the switch, switch on the pipeline and can walk on water, air, oil and so on go. A lot of categories, you can control the on-off, control pressure safety valve, as well as a lot of filtering valves.
Q:What do you mean by "P54" in the valve z962y-p54 100V?
Applicable temperature 540 degrees centigrade;Applicable temperature 540 degrees centigrade
Q:How many kinds of valves are there in the water pipes?
butterfly valveThe butterfly valve has the advantages of simple structure, small volume, light weight, only by a few parts. But only can rotate 90 degrees rapid hoist, simple operation, while the fluid control valves have good properties. The butterfly valve in the fully open position, the disc thickness is only when the medium flows through the power, by the valve the pressure will be very small, so it has better flow characteristics. Our company is mainly metal plastic butterfly valve, eccentric butterfly valve, butterfly valve, inlet butterfly valve, wafer butterfly valve and so on.Globe valveBall valve and plug valve is the same type of valve, only its closure is a sphere, the sphere rotates around the body center line to achieve the opening and closing the valve. A valve in the pipeline is mainly used for cutting, distribution and change the direction of media flow, the ball valve is a new valve in recent years has been widely using.
Q:What does the "PN" mark on the valve mean?
The valve will usually be marked with "DN.PN." these two signs,DN refers to the valve path, and PN refers to the pressure levelFor example: DN25, PN16Refers to the valve diameter of 25mm valve, the pressure is 16 kg (1.6Mpa)
Q:What is the diameter of a general pipe valve?
In fact, the essence of the problem is the corresponding relationship between the nominal diameter and other dimensioning methods. Valves are generally marked with nominal diameter (DN***), such as DN150, DN100 and so on. There are many kinds of marking methods for pipes, such as outer diameter, inch inch, nominal diameter, etc.. Only when the other dimensioning is converted to nominal diameter, the valve and the pipe correspond to each other.
Q:Is the heat jacketed valve fitted with flanged flanges?
Insulation valve is the standard valve, just in order to ensure the link bolt flange to super space, usually a large ball than normal level, such as the use of the path is DN80 flange, flange is DN100, so is the standard, but the size of flange connecting with other valves are not the same.
Q:What is the valve before and after the pump?
Pump in front of the gate valve + one-way valve, after the pump connected valve, so that in the regulation can be clearly aware of the actual pump lift is large, without the impact of system pressure.Valve is the general name of pumps and valves.A valve that is not used in a pump or with a pump.Pump and valve are often associated with the use of the occasion. In other words, where there is a pump, there is usually a valve, where a valve is often required. They are all used for liquid delivery.
Q:How to quickly identify the types of valves?
There are many kinds of valves, such as butterfly valve, ball valve, globe valve, gate valve, check valve, plug valve, plunger valve and diaphragm valve...... Pneumatic, electric, worm, or handle......There are also pictures on the Internet, you can search their respective pictures, shape is visible
