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.
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)Flow curve tending to straight-line. Excellent regulation performance.
5)Various kinds of materials, applicable to different medium.

5.FAQ
1. 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.
2. 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: does it come in when you go over a certain rpm or do the valves change depending on how far you depress the throtle?
- The variable is the valve timing. The spark plug fires a split second before the piston reaches the top of the stroke, to give the fuel a bit of time to burn. But, the faster the piston travels in the bore, that split second gets shorter shorter. So the engine computer changes when the spark plug fires when the valves close, to maximize the power from each ignition stroke.
- Q: Butterfly valve D41W-1, 41, W, 1, respectively, what does that mean?
- This butterfly valve in our factory called butterfly, 4 represents the connection of the flange connection flange is French, 41 in 1 on behalf of butterfly valve, W represents the body seal, is C that is actually the correct type of cast steel, should be D41W-1C. Suitable for ventilation, smoke, and these media.
- Q: What does the triplex of pneumatic butterfly valve mean?
- Generally referred to as "triple parts" as if: filter pressure reducing valve, solenoid valve, with the valve position feedback switch..
- Q: What's the difference between turbine butterfly valve and manual butterfly valve?
- The turbine can light and close the valve here. It is more labor-saving and reliable. It is closed and open. Manual operation is relatively difficult, but the manual action is very fast. Fast switching. General large bore turbine.
- Q: How to use the fire butterfly valve properly?
- Clamp and groove type and signal butterfly valve, the first two have what requirements of installation, the operating handle can rotate to open and close the valve installation, signal wiring, mouth down, to prevent water and caused a short circuit three line grounding and alarm line for leakage protection and monitoring of the valve open or closed, general are in line with the alarm valve or flow indicator matched with water, indicating the spacing of not less than 300mm, no other special requirements
- Q: oil coming from valve into turbo charger
- depends on the year of the duramax, some do have a pvc valve one is on the valve cover on one year and on another year the valve is down at the bottom of the engine it screws in, i would check with your local dealer, the should give you an idea, if the turbo has an line follow it the other is just mainly a vent on the valve cover, is the oil coming in or coming out of the turbo?
- Q: Butterfly valve D71X-1.6C, DN50, there is no difference between C and no C? What do you mean by "concrete"?
- The C indicates that the material is carbon steel and does not indicate cast iron (generally omitted)
- Q: Butterfly valve, two-way pressure and one-way pressure what is the difference?
- Popular, one point one pressure side, a double-sided pressure.
- Q: Hi guys, i asked a question before pertaining to the amount of cylinders and asking if it meant V4 or V6 or whatever.I actually meant to say VALVES, not cylinders. IS there a direct correlation between VALVES and Clyinders..Eg, My car, which is a 2001 Neon LE states right on the engine block quot;16 VALVEquot; in bright letters. I am sure this is a 4 cylinder engine. I haven't had a car that broadcasted the number of VALVES before. Another car I had broadcast that is was a 3.3 Liter V6 right on the engine.Is there a mathematical relationship between VALVES and cylinders, or would my car be braodcasting 16 VALVES, because a 4 cylinder doesn't typically HAVE 16 valves, or what is the story??Recently, I was looking at an altima, and it said 24 valves. Can you tell just by the number of valves if it is a 4 cylinder or 6 cylinder or whatever??Thanks.
- for every cylinder there is 4 valves..
- Q: Butterfly valve structure and working principle
- Butterfly valve structure: Center to clip butterfly valve, single eccentric butterfly valve, double eccentric butterfly valve, three eccentric butterfly valve
