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 to check the quality of the valve?
First of all, to check the appearance of the valve is smooth and smooth. Cast valves without sand holes and obvious flaws. Forged valves check nominal pressure or pound level. Second, check the material of the valve, that is, the material composition, this is very important, the material does not meet the standard on the device will be a big problem. Finally, check that the switch is sensitive and the signs are clear. Test pressure is the last step.
Q:What is the valve?
The definition of a valve "valve" is defined in the fluid system, used to control the direction of the fluid, pressure, flow device. A valve is a device that flows or stops the medium (liquid, gas, powder) in a pipe and equipment and controls its flow. Valve is the control component of pipeline fluid transportation system. It is used to change the passage section and medium flow direction, and has the functions of diversion, cut-off, adjustment, throttling, check, diversion or overflow, pressure relief, etc.. For fluid control valves, valve from the simplest to the most various valves automatic control system used in complex, its many varieties and specifications, the valve nominal diameter from industrial piping and instrumentation valves tiny tolarge diameter 10m valve. The valve can be used for the control of water, steam, oil, gas, mud, all kinds of corrosive medium, liquid metal and radioactive fluid and other types of fluid flow, the valve working pressure from 0.0013MPa to 1000MPa ultra high pressure, working temperature from ultra low temperature to high temperature of 1430 DEG -269. Control valve can be a variety of transmission methods, such as manual, electric, hydraulic, pneumatic, worm gear, electromagnetic dynamic, electromagnetic hydraulic, electric hydraulic, pneumatic and hydraulic, gear, bevel gear drive; in pressure, temperature or other forms of sensor signals under the action according to the requirements. Or do not rely on a simple sensor signals to open or close the valve on the drive or automatic mechanism to make the opening and closing parts for lifting, sliding, rotating or turning motion, thus changing the size of the flow area to achieve its control function.
Q:Add a valve on the trachea, when the valve behind the use of gas units,
Online search "air switch", many suppliers.You may choose your pipe according to your pipe diameter.The flow meter can also be used to control the flow of operation
Q:What does the valve "4" mean?
This is an inch inch size, 4 inches =1/2 = 25.4mm = 12mm
Q:What does LBC mean in a valve?
LB and 800 are together. 800LB means 800 pounds of stress, and P should be PRESSURE.
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:The valve has a clear opening and closing sign. What does this sentence mean?
Simply speaking, a gate valve, hand wheel will be above the arrow and open and close the text, indicating that you are clockwise valve open or counterclockwise valve open, so as not to make mistakes, accidents. Other valves are similar in sense and sign.
Q:Valve legend
F means a pressure gauge or thermometer; as to which type of valve, the marking should be a stop valve.
Q:What is the main function of the valve?
Acting on switch control, flow regulation, remote control, etc.
Q:In the fire drawing, what valve does the following valve represent?
1, fire drawings, the following valve signal valve and alarm valve.2 、 signal valve is the best matching product of automatic fire sprinkler system. The structure characteristics and working principle: the top design electrical device the butterfly valve of the worm and the worm gear driving device, and with the stem straight connecting transmission. In the closed precision electromechanical device, opening mechanical instructions and imported electrical components and parts with rust proof valve. The output signal is stable and reliable for a long time.3 、 alarm valve products are wet alarm valve, dry alarm valve, rain alarm valve, pre acting alarm valve and so on. It is the core component of wet automatic sprinkler system. The water enters from the bottom of the valve body and closes the check valve through the dead weight inside the valve body to form a standby system with water pressure. The high pressure gauge indicates the system pressure, and the low pressure gauge indicates the pressure outside the system. When the protected area fire, high temperature make the nozzle temperature sensing element of blast nozzle sprinkler system, pressure drop, the valve opens, water flows continuously into the system, the nozzle opening, continuous sprinkler. At the same time, a small amount of water enters the alarm tube from the inner hole of the valve seat, passes through the filter, the retarder, and then pushes the hydraulic alarm to alarm. In addition, after the pressure switch is activated, the electrical signal is issued and the make-up water is started.
