1. Manual Wafer Butterfly Valve Description

1) DN40-1200 PN10/16
2) ISO9001:2008 and CE Certificates
3) Relable OEM Factory, high quality, low price, fast delivery

4) Many patents

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.  

2.Main Features of the Manual Wafer Butterfly Valve 

1)Small in size and light in weight and maintaince.It can be mounted whereever needed.

2)Simple, compact structure, quick 90 degree on-off operation.

3)Disc has two-way bearing, perfect seal, without leakage under the pressure test.

4)Strong wash and brush resistance and can fit to bad working condition.

5)Center plate structure, small torque of open and close.

5.FAQ

1. What is manual wafer butterfly valve?

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?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 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's the difference between a butterfly valve and an eccentric butterfly valve? What is the difference in field applications?
Avoid friction and wear on the sealing surface!And, at the time of closing, and opening the opposite, there is a better sealing effect! Now generally use eccentric butterfly valve as the main. That's all I know! If there is any mistake, please forgive me!
Q: How can one - way sealed butterfly valves and two-way sealed butterfly valves be distinguished?
Two way hard sealing butterfly valve:Two way butterfly valve on the valve body usually does not indicate the direction of the media arrow sign, in the design of two-way sealing butterfly valve stem force is greater than one-way butterfly valve stem. The same diameter, pressure butterfly valve, two-way sealing butterfly valve rod diameter than one-way sealing butterfly valve stem diameter. At the time of installation, the butterfly plate can face or back the direction of the medium, without considering the flow direction of the medium.
Q: 1st where is my zone valve? I have an old Burnham gas baseboard heater2nd What do I do?My last resort is calling a proffesional.
First: Wat make you tinkling that the zone is bad? Every zone cooperate with 2 other essential parts: thermostat and power supply, In 90% of my carea, people firs go with their thinking to zone, but only 10% was realy zone. The first thing to check is termostat and power. you could do this very simply by removing termostat wire and tickling them together several times, if they have spark, than the most prabably is just thermostat broken
Q: oil coming from valve into turbo charger
The last two answers were wrong. Duramax motors have a Pcv valve. It stands for positive crankcase ventilation and every engine has one that I am aware of and it's to relieve the air pressure built up in the crankcase from the pistons moving up and down. The Pcv allows atmospheric air pressure inside then crankcase. If there is a lot of air pressure coming out of the Pcv you could have bad valve seals or worn piston rings allowing massive amounts of air being forced into the crank case. The Pcv valve on 2003 and older have the Pcv built into the valve cover. It is a box shape cap that has a spring and diaphragm under it. Old question just thought I would clear that up for the 2 people not so mechanically inclined that answered last.
Q: Specifically an engine valve retainer.
Valve Spring Retainer
Q: Butterfly valve network and ordinary butterfly what is the difference?
Butterfly valve used in the network structure, closed with the more closed, the more tight function, reliable sealing performance, after opening and closing, make sure that the cover is completely out of touch, to ensure that the sealing surface is not damaged. The sealing surface is made of stainless steel, corrosion resistant, high temperature resistant, long service life. With two-way sealing function, medium flow is not affected by the installation restrictions (if only one-way control medium should be used to seal the installation direction) is not affected by the spatial units, can be installed in any direction.
Q: Who can give me a download UG butterfly valve, needle valve, diaphragm valve standard model address, Japanese standard, American Standard.
Give you the address bar, this is a three-dimensional CAD model library of an online version of the real registered mail, free of charge, there are hundreds of Chinese and foreign manufacturers of the product model is available for download, such as ABB, SMC, FESTO, AIRTAC, CAMOZZI, MISUMI etc..
Q: Which is expensive, butterfly valve?
Gate valve and butterfly valve can not simply take the price there to compare, look at the actual design requirements of the project. General small caliber are selected by the valve, because of better sealing performance, service life is long, the maximum diameter of valve is usually choose to use the butterfly valve to the pipeline DN800800 above, because the valve is cheap, the price is only half of the large diameter valve. Also some pipes from the use of quality point of view, will choose the gate valve. How to use it, please mark the map
Q: What is the D37-10Q butterfly valve?
D- butterfly valve (valve type); 3- worm (drive); 7- pairs of clamp (connection); 10-PN1; nominal pressure of 10 kg; Q- ductile iron (valve body material).
Q: Buried extension butterfly valve is buried or need to repair the valve well, can build the valve well, the extension rod butterfly valve installed in the valve well, the extension rod to avoid covers, the top of the valve well out, so that the hand wheel in the ground operation.Atlas S143 is less than the inner diameter of DN150 valve wells only 1200mm, DN200-DN250D diameter of only 1400mm, 700mm valve covers, valve rod and a handwheel to lengthen through the valve cover, valve wells is built to cover the embedded pipe or tube? Is there a standard atlas?
The establishment of a repair valve well, easy to repair, usually hydrogen long rod butterfly valve installed in the well. But if the quality of buying long stem butterfly valve, it can also be buried directly, not easy to bad
