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:How does the valve open?
Turn the valve counterclockwise, turn clockwise, or turn left, right and leftYou turn the valve to the left.
Q:What do you mean by "P54" in the valve z962y-p54 100V?
P54 is the body temperature, heavy rain or equal to 545 degrees, 100V is 10Mpa, that is 100 kilogramsThere are all the valves on the nameplate
Q:What is the term "Z41H-16C" on the line?
Therefore, the opening position of the valve is determined by the position of the gate (i.e. the stroke).Z41H-16C closed, the sealing surface can only rely on medium pressure to seal, that is, only rely on the media pressure to the gate sealing surface pressure to the other side of the seat to ensure the sealing surface seal, which is self sealing. Most of the valve is forced seal, that is, when the valve closes, to rely on external force to force the gate to the seat, in order to ensure the sealing surface sealing.
Q:What are the major brands of valves abroad?
Fisher (Emerson's brand, pneumatic head and regulating valve is good) mountain Wu (Japan's control valve is doing well)
Q:What's the material of j41h-16p's valve?
The j41h-16p valve is a stainless steel globe valve.The working principle of stop valve: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.The closing principle of the valve is to rely on the valve bar pressure, so that the valve sealing surface and seat sealing surface close together, to prevent the circulation of media.The one-way valve can only medium flow direction when installing. The structure length of the stop valve is larger than that of the gate valve, and the fluid resistance is large, and the reliability of the sealing is not strong during the long-term operation.
Q:What are the ten major brands of China's valves?
If you want to buy fluorine valve, you can go to Shanghai corrosion-resistant valve group Co., Ltd., and what questions contact me?!
Q:Pump, valve, these belong to the material?
The pump belongs to the equipment (electromechanical equipment), and the valve belongs to the pipeline material.
Q:G what's the meaning of the valve?
G is the diaphragm valve, valve type code, there are other types of valve code.A D is a safety valve, butterfly valve, check valve (H valve), J is the cut-off valve, throttle valve is L, P is Q is the drain valve, ball valve, S trap, U X is a plunger valve, plug valve, Y valve, Z valve.
Q:What valve is the YQZ45X-16Q?
Specifically, YQ usually is the enterprise code, Z valve, 4 representative flange, 5 representatives of the dark bar, X (soft) rubber seal (gate coated with rubber material), nominal pressure 16 representative (PN) 1.6Mpa, Q on behalf of the valve body is made of ductile cast iron. If you add the valve bore (DN), it will be more detailed.
Q:What kind of valves are best used for sand drain valves?
Looking at the domestic sand discharge conditions, the more commonly used plate valve and butterfly valve these two, but generally reflect the service life is not long, it will not be long before the sand leakage, the need for regular maintenance, low efficiency, affecting production. In recent years, the industry has also appeared in various kinds of new type of valve, take little effect, but also has a valve using the excellent response, talent shows itself, long service life, no maintenance, model for the special valve industry Yu powder FQD672 and FQD643,It is understood that the valve industry has been to focus on Yu powder (sand) on body condition, especially the delivery of viscous pneumatic conveying system, special valve type FQD672 and type FQD643 powder successfully developed specifically for the design of sand material conditions, erosion resistant, anti adhesive seal design, automatic compensation, to ensure zero leakage absolutely, efficient and longevity, is applied to the resin sand casting industry (coarse sand) sand core shape of the high-speed exhaust conditions, you can try to understand Baidu......
