Specification
The flexible butterfly valve is applicable to foodstuff, pharmacy, chemical industry, Prtroleum, electrical industry, textile, paper making, drain and air pipelines to control and stop the flow, with the function of compensating expansion and condensation inder the condition of temperature less than 80°C, nomral pressure less than 1.6MPa.
Main features:
Novel and resanalble design, unique structure, lightweight, convenient operation, quick open/close.
Flexible butterflyy valve is convenient to install, change and repair the valve, basides of adjusting and stop funtion and expansion and condensation funtion since temperature difference from compensation pipelines.
It is adjusttable and changeable for seal parts an reliable sealing function.

- 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: I got my timing belt done on a 1999 Civic Si on September 26 @ 113,699 miles. at 116,9xx miles I bent a valve on my third cylinder. How likely is it that the timing belt is the reason why this happened? I heard that if the timing belt is a tooth or so off, it could bend a valve. So is it likely that this could have happened? Anyway to check?
- If it was a timing belt issue it woudn't have only been one cylinder. And usually if it's only off by one tooth, it just runs poorly. IT has to be off by quite a bit, or the belt has to straight up break to bend a valve,, if that happened it would have made a horrible clanging noise repeatedly before it eventually sputtered out. the 1999 Si revs to what... 8000 rpms? You didn't happen to miss a shift and over-rev the engine, did you?
- Q: When will Butterfly Valves be used?
- 3, there are anti-corrosion requirements of the pipeline, such as sewage, chemicals, etc.;4 、 pipes that regulate flow control requirements, such as quantitative systems;5, there are open and close, fast opening and closing requirements of the protection of the pipeline system, rapid cutting......

- Q: What is the meaning of the D341*5-10 / 16ZB1 turbine butterfly valve flange said?
- D: for clamp, 3: turbine head 4: flange connection 1: vertical plate X5: Ding fine rubber 10/16: nominal pressure Z: gray cast iron valve body, B1: valve plate material is ductile iron
- 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
