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.
2.Main Features of the Manual Wafer Butterfly Valve
Butterfly valveis exclusive pneumatic elements controlling the actions of the brake and cluth of a press. It ensure that cluth and brake maintain a certain procedure of gear-in and release, i.e. when press starts the brake shall first release for 0.03 sec before clutch gear-in; and when the press stops, the clutch shall first release for 0.01 sec before brake active.

5.FAQ
1. 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.
2. 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.
3. 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.
- Q: What do you mean, handle, butterfly valve, hard back and soft back?
- Hello, soft sealing butterfly valve is generally divided into skeleton, seat and frameless valve seat, the skeleton of the general material: resin, aluminum, iron.. Etc.. With back seat is on the back of the vulcanized rubber, without skeleton, valve seat is rubber.
- Q: 16 inches below the choice of electromagnetic valve can be the same, it turned out to be DN200 election 1/4, and now there are DN350 can also use this? With it, limiter, pressure relief valve, locator model will change?
- DN200 pick 1/4DN350, DN400 corresponding solenoid valve, you can choose 3/8 hose 12mmOther accessories are related to valve path and pressure. If the same series, the valve has no change at all.
- Q: How many kinds of butterfly valves are there?
- Also known as butterfly valve, control valve has a simple structure, can be used for low pressure pipeline valve switching control is closed parts (disc or disc) is a disk, around the valve axis to achieve the opening and closing a valve, the valve can be used to control the flow of air, water, steam steam, all kinds of corrosive medium, mud, oil, metals and radioactive liquid media and other types of fluid. On the pipeline, mainly from cutting and throttling. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation.[structure]The utility model is mainly composed of a valve body, a valve stem, a butterfly plate and a sealing ring. The valve body is cylindrical and has short axial length and is internally provided with a butterfly plate.
- Q: I am confused as to the answer of this question. Please help.Indicate the status of the mitral, tricuspid and semilunar valves (whether they are open or closd) during the various phases of the cardiac cycle. Discuss the pressure in each of the relevant chambers or blood vessels during the phases with reference to the opening or closing of the valves.
- A heartbeat is a two-part pumping action that takes about a second. As blood collects in the upper chambers (the right and left atria), the heart's natural pacemaker (the SA node) sends out an electrical signal that causes the atria to contract. This contraction pushes blood through the tricuspid and mitral valves into the resting lower chambers (the right and left ventricles). This part of the two-part pumping phase (the longer of the two) is called diastole. The second part of the pumping phase begins when the ventricles are full of blood. The electrical signals from the SA node travel along a pathway of cells to the ventricles, causing them to contract. This is called systole. As the tricuspid and mitral valves shut tight to prevent a back flow of blood, the pulmonary and aortic valves are pushed open. While blood is pushed from the right ventricle into the lungs to pick up oxygen, oxygen-rich blood flows from the left ventricle to the heart and other parts of the body. After blood moves into the pulmonary artery and the aorta, the ventricles relax, and the pulmonary and aortic valves close. The lower pressure in the ventricles causes the tricuspid and mitral valves to open, and the cycle begins again. This series of contractions is repeated over and over again, increasing during times of exertion and decreasing while you are at rest. The heart normally beats about 60 to 80 times a minute when you are at rest, but this can vary. As you get older, your resting heart rate rises. Also, it is usually lower in people who are physically fit.
- Q: What do D71, D371 and D341 represent in butterfly valves?
- D71 is a handle to clip butterfly valveD371 is a turbine to clip butterfly valveD341 is a manually operated double flanged butterfly valve
- Q: The flow ratio of area and maximum flow area of the valve is? If it refers to the opening of the valve rotation angle? Butterfly linear closure refers to the butterfly valve at constant angular velocity close? When the change trend of flow is what? These valves problem bothering me for a long time,
- Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis rotation, so as to achieve the opening or closing or adjustment; actuators have electric or pneumatic, and so on, through the transmission device to drive the stem, valve plate rotation;
- Q: Do you use the straight stem butterfly valve in the fire fighting engineering?
- Bar valve bar, did not hear the bar with butterfly valve, ah, there are pairs of folder and hand wheel type bar
- Q: Types of butterfly valves
- There are clip on butterfly valves and flanged butterfly valves,Manual, pneumatic, electric,
- Q: How to control the single acting pneumatic butterfly valve?
- Single acting pneumatic butterfly valve can be divided into gas open type and gas closed type, which is usually called "normally closed" and "normally open". This is very critical. The single feature pneumatic butterfly valve is the biggest feature of its spring reset function, when the loss of gas or sudden failure, you can automatically restore the original state. So it's important to open the air or air this time.
- Q: I did a compression check on my 350 chevy. I have low compression of 175psi on one cylinder.The other seven cylinders range from 195psi to 205psi Could the valves be too tight on the cylinder with 175 psi compression?
- unless they have been tampered with that wouldn't be it,they usually wont tighten up on their own,i would suspect maybe a valve with a slight burn place on it that's causing that to happen or a ring causing you to loose that much compression,try adding a small amount of oil in the cylinder and then do the compression test again,that will tell you if its a ring or a valve,that's a big loss of compression ,and when you see that much of drop its usually a burnt valve.good luck.
