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:Signal butterfly valve installation or other valve installation
The blue one is the separate body, and the red one is the welded flange on the pipe. There is rubber on the valve body, and it can be sealed with flange. This is determined by the structure of the butterfly valve, usually DN150 of the small diameter butterfly valve are installed this way. It comes with flanges, but the prices are much higher. Small caliber general butterfly valve is generally used for low pressure, leakage requirements are not high, so rarely use its own flange. With flanges, it is generally used in petrochemical systems and has a much higher pressure level.
Q:What is the difference between valve j941H-40 and j41H-40?
The difference is that one drive is electric, one is transmission, and the other is manual."Valve design manual" showsJ- stop valve9- electric4- connection means flange connection1- through typeH- sealing surface is alloy40- operating pressure is 4.0Mpa (or 40 kg)More than one, 9, 9 fingers, electric, more than an electric.Valve (Famen) 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:Is the valve galvanized?
Butterfly valve gate, some hot-dip galvanized, and other valves are not.
Q:How do I open the gas valve?
Third: in the following there is a black disk like thing, commonly known as the gas sound core. This one is the same as the second one, half or all. 1, according to the routine, now the handle position shows that the valve is open. 2, if the handle rotated 90 degrees, the gas pipeline gas has no change, should be the stem slipped, can not drive the valve ball rotation. Try rotating several times. If it still doesn't work, ask a professional to check it out.
Q:Why can't the clip type check valve be directly connected with the pipe mouth or other valves?
The clip type check valve is made up of two discs to prevent backflow.If the clip check valve is connected to the other valve, the disc may touch the valve and cause the check valve not to be fully opened or closed. This is a preliminary analysis of "enter the valve", for reference only!
Q:Is there any difference between the valve and the water valve?
There is no difference between the low pressure lubricating oil pump, as long as the excuse right on the line, not to pressure, design pressure ball valve common does not exceed 3MP, the maximum pressure of only small gear pump vane pump is 2.5MP, the other piston pump, gear pump, the pressure is above 6.3MP. Certainly not. Unless using high pressure water pipe valve.
Q:What is the diameter of a general pipe valve?
What a big pipe? The normal valve clearance is 1cm
Q:What is the difference between the adjustable range of valve 50:1 and 100:1?
Adjustable ratio is also called adjustable range, if to R to indicate, then R=Qmax/Qmin should pay attention to the minimum flow, Qmin and leakage of different meanings. The minimum flow refers to the lower limit of adjustable value, it is generally the maximum flow rate of Qmax 2%~4%, and the leakage is fully closed when the leak valve, it is only the maximum flow rate of 0.1%~0.01%.Adjustable range 100:1 generally can not reach, the accuracy of this valve is very high.
Q:What valve should be used to test the water valve?
Switch and multi way valve in the pipeline not only can flow, and flow diversion, flexible control of the medium, but also to turn off any channel to the other two channels. This kind of valve should be installed horizontally in the pipeline. Classification of ball valve: pneumatic ball valve, electric ball valve, manual ball valve.
Q:What are the uses and differences of gate valves, butterfly valves, ball valves and other valves?
The use of the same difference, you can see the shape
