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:What does "1/2" mean on the valve?
1/2 on the valve indicates that the ends of the valve are 1/2 inches in diameter.Valve is a control component in the fluid delivery system. It has the functions of closing, adjusting, guiding, preventing reverse flow, stabilizing voltage, shunting or overflow and releasing pressure.Valves used in fluid control systems, from the simplest stop valve to a very complex automatic control system used in a variety of valves, a wide range of varieties and specifications. Valves can be used to control air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow. The valve according to the material is divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316), chrome molybdenum steel, chromium molybdenum vanadium steel valves, valve, dual phase steel valves, plastic valves, non-standard customized valve material etc..
Q:Valve installation
It looks a bit like the butt weld butterfly valve. The two sides are welded to the pipe. There is a step on either side of the valve. Overhead welding
Q:Can the gas valves be switched off regularly?
No one at home, there are children, stove use time is relatively long, the gas hose has not changed for a long time, as far as possible off the stove front valve. Regular checks are necessary. For a long time, try the stove before the valve is intact, hose aging, safety first. Selection of large brands of stoves, quality guaranteed
Q:Is the valve clockwise?
Tap water valve is generally divided into two kinds, one is ball valve, and the other is gate valve. The ball valve wrench is vertical when the water pipe is closed, is a twist or reverse, 90 degrees wrench and water pipe is open when the direction; valve handwheel clockwise turn off, anti clockwise turn is open. Valve in the application should not be twisted too tight, so as to avoid the thread buckle, spool off. Ball valve applications save effort and durability.
Q:Which valve can play a good regulatory role?
A wide range of valves, the function is different, although like conventional butterfly valve, ball valve can play a regulatory role, but their role is not linear, so if you need to adjust the precision of the valve, it is best to select the control valve.
Q:How about the quality of FITOK valves?
Purely under the banner of what import, in fact, everyone knows, is the genuine domestic goods.
Q:How much is the 150LB of the valve?
Valves can be used to control air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow.
Q:How to quickly identify the types of valves?
The "Practical Handbook" valve design on the valve structure, with precision, surface roughness and typical design standard, the valve has hundreds of models, and continue to have a new valve, see a written one, is shorthand
Q:What is the normal temperature on the valve?
What's the valve?. Conventional valves are 425 degreesIf it's on the oil field. It's only 120 degreesAt normal temperatures are below 120 degrees. A lot of valve sealing surface can only reach 120 degrees
Q:What are the uses and differences of gate valves, butterfly valves, ball valves and other valves?
Valve and ball valve is generally used in the main pipe, long-term use, butterfly valve is often used frequently,
