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: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?

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:What are the functions and uses of butterfly valves?: Butterfly valve is fully open to fully closed is usually less than 90 degrees, butterfly and butterfly stroke itself has no self-locking capability, in order to position the disc to install the valve stem on the worm gear.Using worm gear reducer, not only can the butterfly plate have self-locking ability, so that the butterfly board stops at any position, but also can improve the operation performance of the valve.
