1. 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 .
2.Main Features of the Butterfly Valve
(1) 90° movement for full open/close position.
(2) Excellent control characteristics.Tight shut-off even after innumerable operations.
(3) Installation cost considerably reduced because of very low weight and compact design.
(4) Longer life and reliable service with minimum component wear.
(5) Renewable seats. No supplementary gasket required with the adjacent pipework.
(6) Body & Stem totally protected from service fluid.

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:How do hydraulic butterfly valves work?
- The valve hydraulic device is mounted on the valve drive shaft. The driving shaft of the valve is fixed with a transmission spline, and the crank (with an outer spline) is sleeved on the driving shaft. When the hydraulic system works normally, through the gear sleeve, the transmission spline is connected with the crank. Thus, the hydraulic cylinder drives the crank, and the spline on the crank passes the torque to the transmission spline by means of a gear sleeve. Because the driving spline is fixed on the driving shaft, the driving shaft rotates and drives the valve plate to start and close. Sorry, the picture doesn't come up
- Q:I need a valve cover gasket replacement because mine is leaking a tremendous amount of oil. The mechanic says it will cost about $269.00 plus tax. I wanted to make sure this figure was the average since I do not know a lot about cars. My car is a Mitsubishi Diamante 2001.
- The gasket set is probably $ 20, so double that to $ 40..... 270 - 40 is 230, divided by 2 man-hours, which is the usually dealership minimum, gives $ 115 an hour. I DON'T THINK SO !!!! Unless you live in Hawaii where everything is expensive, that sounds steep.... real steep. Dealers around here get like $ 85 an hour, so two hours is 170, plus 40 is 210 bucks; Still killer money for the dealer..... I'd question that estimate ask if there is some extraordinary challenge to working on your car. It is possible there are accessories mounted over the valve cover that will have to be moved, or that's it's a canted V-6 with one valve cover tucked up against the fire wall. Be nice, smile, ask questions.... Maybe even have someone show you what has to be moved on your engine to get at the valve cover(s). If you're going to pay that much $$$, you should learn something, also.

- Q:Types of butterfly valves
- There are clip on butterfly valves and flanged butterfly valves,Manual, pneumatic, electric,
- Q:1988 volkswagon cabriolet, rabbit tried mystery oil let sit for a week having trouble with stuck valves even taken a wrenrch to manually unstick. help any suggestions 4 cyclinder car has been sitting up for about 4 years
- The only reason for a stuck valve is if it bent from a thrown timing belt. Sitting 4 years will not cause valves to stick usually, because there is always some oil leakage from the head, that prevents rust. How do you know the valve is stuck? Have you done a compression test, checked the valve clearance? When you say you take a wrench to manually unstick it, it would help to know what you mean, because there is no place to put a wrench that would help unstick a valve that was stuck. You need to tell us much more.
- Q:Hey YA! I am looking at getting an 01 Honda Prelude this month and valve adjustment keeps coming up when people discuss this car and other cars as well. What is this? Does it cost a lot to do, and is it important? Thank you!
- Some cars have little hydraulic gizmos to keep the valves more or less where they're supposed to be. Doing without them is, according to some, a tad more precise, but you have to have the valves checked now and then. (On my old Celica, it was a 60k maintenance item.) It will probably run a hair better afterwards.
- Q:The difference between the electric control valve and the electric butterfly valve, respectively, the application situation
- Butterfly valve switching speed, fluid resistance is small, but the flow control is not good, suitable for only fast opening and closing occasions. Control valve switching speed is relatively slow, fluid resistance, but the flow control of the linear good, suitable for flow control requirements of the occasion.
- Q:How warm is the PTFE butterfly valve?
- Ordinary PTFE clip butterfly valve normal temperature tolerance of about 120 degrees, instantly to about 150 degrees
- Q:i just finished installing a sprinkler line for my lawn and i used anti siphon valves and 4quot; sprinkler heads. it says in the manual that it has to be at least 6quot; from the highest sprinkler. i think i made a mistake. i installed it 7quot; from the highest 'sprinkler line' . will i have a problem with that regarding the operation of the anti siphon valves and the sprinkler system itself?
- anti siphon valves are junk. just install regular valves and put in a backflow preventer on your mainline before all the valves, but right after the shut off vavles.
- Q:Does the pneumatic butterfly valve need electricity?
- Pneumatic butterfly valve generally not need steam can Shandong Yuhong automatic control valve
