1. Manual Wafer Butterfly Valve Description：
A butterfly valve consists of body ,stem ,disc , actuator (manual actuator, worm-gear actuator , aerodynamic actuator or electric actuator) , and wafer type butterfly valve can implement the process for turning on turning off and regulating the flow by the circumrotation of stem and disc that is droved by actuators.
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.

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: My caravan is a bit sluggish on the pick up, I replaced the wires/plugs and the electronic distributor(I think thats what it is..). still a bit sluggish. Should i look at the valve gasket? Or fuel filter, or fuel pump next? 03 caravan sport 3.3L
- There is no electronic distributor on your caravan it uses a coil pack To the 1st poster there is no valve pan gasket you have valve cover gaskets. The fuel filter on your van is Incorporated in the fuel pump module located inside your fuel tank. There a several things that can contribute to sluggish performance, look at your exhaust and make sure it is not bent/collapsed/restricting Dodge Chrysler Jeep Tech
- Q: In the pipeline attached building Atlas 05S502, in the middle of a water meter and check valve, the two sides are divided into two butterfly valve, want to ask why to arrange this way, what is the role of the two butterfly valve?
- Check the water gauge and check valve on both sides to facilitate the maintenance and replacement of water meter and check valve.
- Q: What does the model D373H-16C of butterfly valve mean?
- D373H-16C said: D type butterfly valve butterfly valve 3 said, said 7 of the turbine, said clip, 3 said the three eccentric (swash plate), 16 C nominal pressure, said carbon steel. In fact, if you want to understand this, to understand the valve 3.07ghz, later met have to be attached to the valve. 3.07ghzModel for valves, valve number indicates valve type valve should normally be that type, drive type, connection type, structural features, nominal pressure, sealing surface material, body material and other factors. Standardization of the valve type of valve design, selection, distribution, provide more convenient. The type of valve types and materials are more and more more models of the preparation of the valve will become more and more complicated. Although the preparation of our valve type unified standard, but gradually can not meet the needs of the valve industry. At present, the valve manufacturer usually adopt a unified numbering; not uniform numbering, the manufacturer can make out no.methods according to their own situation. Unit two unit three unit four unit five unit six unit seven unit
- Q: What are the advantages of butterfly valves?
- D. sediments are not readily accumulated;The E. is compact and has little installation
- Q: Gate valve and butterfly valve which is installed when there is a direction?
- There is no direction when installing the valve. The butterfly valve has an eccentric butterfly valve which is in the direction of installation
- Q: What are single eccentric and double eccentric in butterfly valves? What's the difference, please explain in detail?
- Double eccentric butterfly valve: in the single eccentric butterfly valve on the basis of further improvement of forming, is the most widely used double eccentric butterfly valve. The structure features that the center of the stem deviates from the center of the disc as well as the center of the body. The effect of the double eccentric valve can be opened immediately after the disc from the valve seat, substantially eliminating the unnecessary disc and valve seat over squeezing, scratching phenomenon, reduce the resistance from the open, reducing the wear and improve seat life.
- Q: Butterfly valve D71X-10 and butterfly D371X-10 what is the difference?
- One more 3 in D71X-10 stands for adding a worm gear to the valve. What are the same, the difference is driven by the handle into the drive, gear drive, worm gear drive for large caliber butterfly valve a little less, because the valve torque is big, big, hard to handle and can rotate, and if the worm, you can turn a few laps handwheel. If there are other questions, we can continue to ask questions, the city butterfly valve manufacturers
- Q: Specifically an engine valve retainer.
- TRhe retainer and locks works together to hold valve to spring and keep valve from falling into the cylinder and spring from coming off the top. The locks are tappered, small end at bottom, big end at top. You compress the spring down, drop retainer over valve, put locks in groove of valve stem and pull up on the retainer to lock the retainer and locks in place, the relese the pressure off your spring compressor and the valve spring now holds pressure up on retainer which forces up on the big end of locks and holds everything together
- Q: Fire signal butterfly valve what role?
- Signal butterfly valve should be human action monitoring alarm, once closed, that is, to the system alarmYou ask the two time, I answer two times, you give two points
- Q: What kind of butterfly valve is sd342x?
- Sd342x: two-way double eccentric soft sealing butterfly valveS: two way pressureD: butterfly valve3: turbine operation4: flange connection2: double eccentricX: rubber sealProbably the shape is not so good in appearance,Double eccentric mostly elastic sealThree eccentric is multi-layer sealHope to be of help to youOpened valve Co., Ltd. on the production of butterfly valve
