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:Which direction is the valve? Which direction is it?
Generally: clockwise, counterclockwise, looseYou can also see the logo on the spool
Q:What's the name of the valve?
This is the discharge valve, the lower part of the handle protruding part of the valve is the sealing device. The overall material should be brass, which is typically made by equipment manufacturers.
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
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:What valve is the DN 25?
DN25 is just a caliber, a variety of valves, depending on your actual needs to buy Valves, water or gas, or other special functions, are the basis for the purchase of the valve must be provided

Q:What are the other valves used for the control of dual-use items?
This product is in the operation of import and export trade, electronic key enterprises must be able to operate
Q:Air compressor out of the gas with what kind of valve control okay, globe valve or other?
Air compressor all copper safety valve (AQ-20) (AQ-25)Air compressor, air release valve and so on. The air compressor rated exhaust pressure is divided into low pressure (0.7~1.0MPa), medium pressure (1.0~10MPa), high pressure (10~100MPa) and ultra high pressure (100MPa or more), to see what kind of installation you are and use
Q:What does the "XV" valve mean?
XV if in front of the valve position, such as XV2211-011, then the XV indicates the switch valve, which is a representation of the Control Valve relative to the regulating valve.
