Q: What's the difference between the three eccentric butterfly valve and the two eccentric butterfly valve?: The structure features that the center of the stem deviates from the center of the disc as well as the center of the body. The effect of the double eccentric valve can be opened immediately after the disc from the valve seat, substantially eliminating the unnecessary disc and valve seat over squeezing, scratching phenomenon, reduce the resistance from the open, reducing the wear and improve seat life. Three eccentric butterfly valve: to high temperature, must use hard seal, but the leakage is large; to zero leakage, must use soft sealing, but not high temperature. In order to overcome the double eccentric butterfly valve this contradiction, and the butterfly valve for third times eccentric. The so-called third eccentric, that is, the shape of the sealing pair is not a positive cone, but rather oblique cone.

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? Or fuel filter, or fuel pump next? 03 caravan sport 3.3L: There is no electronic distributor on your caravan it uses a coil pack To the 1st poster there is no valve pan gasket you have valve cover gaskets. The fuel filter on your van is Incorporated in the fuel pump module located inside your fuel tank. There a several things that can contribute to sluggish performance, look at your exhaust and make sure it is not bent/collapsed/restricting Dodge Chrysler Jeep Tech

Q: How can I get the fire signal butterfly valve?: 1, the signal butterfly drive by the worm gear drive shaft and butterfly plate rotation, realize the opening and closing and control flow. 2, rotating the handwheel worm gear to the disc to open and close and adjust the flow to the handwheel clockwise rotation for the valve closed. 3, worm gear is arranged in the box body micro switch has two forms: A, in the gear box body is provided with open and close direction two microswitches, respectively, when the valve fully open and close action, connected to the control room "valve open" valve off "light source, the quasi it shows the state of the valve switch. B, in the driving device is arranged in the box body the microswitch (disc position close to 0 degrees), when the butterfly plate from 0 degrees to 40 degrees when the position of a micro switch, the output valve closed signal, 40 degrees to 90 degrees when the position of another pair of normally closed output valve opening signal. A cam that adjusts the touch microswitch and shows the different positions of the disc.

Q: I have a 1993 Oldsmobile Cutlass Supreme and I think I have the case of the blow-by. The engine had high mileage, but was rebuilt b/c it stalled while driving. 3.1L V6 gasoline engine. The fuel filter and the fuel pump are brand new. Now we have the same problem a few months later. It stalls while driving. Its been sitting a while and won't start by itself, so I pulled off the air intake hose off of the air filter to spray starting fluid into it. I noticed oil puddled in the air intake hose, so I looked for the PCV valve on the rocker cover. There is a tube going from the air-intake hose to the rocker cover. I popped out the tube from the rocker cover and there is no PCV valve. Just tube. Is that where the PCV valve is supposed to go? If not, where can I find it on the engine? And could that possibly fix the blow-by and the stalling engine? I'd appreciate any help. Thanks in advance.: top of the manifold

Q: How warm is the PTFE butterfly valve?: PTFE butterfly valve, sealing surface of fluorine plastic, temperature -29 ~ 450 degrees

Q: What's the difference between cut-off valve, gate valve and butterfly valve? What's the difference in the working principle?: Stop valve, leak small, gate valve, leak big, butterfly valve switch fast

Q: What are the butterfly valves models?: Sealing surface material score:(1) soft sealing butterfly valve.1) the sealing pairs are made of non-metallic soft materials, which are made of non-metallic soft materials.2) the sealing pair is made of metal hard material and is made of non-metallic soft material.(2) metal hard sealing butterfly valve. The sealing pair is made of metal hard material and is made of metal hard material.According to the form of sealing:(1) forced sealing butterfly valve.1) elastic sealing butterfly valve. The pressure of the valve seat, seat, or plate is produced when the seal is closed by the pressure from the valve.2) additional torque seal butterfly valve. The seal is produced by a torque that is applied to the valve shaft.(2) pressure sealed butterfly valve. The pressure is greater than the pressure on the seat or plate.(3) automatic sealing butterfly valve. The pressure of the seal is automatically generated by the pressure of the medium.

Q: Butterfly valve in use when should pay attention to what problems?: In the process of using the butterfly valve, you should timely notice valve state, without excessive loosening, no abnormal leakage, or abnormal high temperature and so on, if there is abnormal, should immediately close the valve, to identify the reasons for the problem, treatment after use, it is also very important.

Q: DN80 flange butterfly valve, DN80 flange butterfly valve DN80, flange butterfly valve DN80 what is the difference?: Of course there are differences, the general market sales of the DN80 are many flange plate copper rod butterfly valve, quality can not reach the national standard, to use copper rod copper butterfly valve quality is king.

Q: The difference between vertical and horizontal butterfly valves in municipal water supply: Function is no difference, mainly the installation conditions are not the same, vertical valve shaft in the vertical direction, the valve well on the deep, horizontal valve shaft in the horizontal direction, the valve width to be larger, and the other is no difference
