Q:Butterfly valve switch direction respectively?

If there is no arrow on the handwheel, the indicator on the turbine has been damaged, you can put your ear on the wall of the pipe, turn the handwheel, and through the sound of the pipe medium to determine the direction of the switch.

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:oil coming from valve into turbo charger

it's located on pg 61222 of gm shop repair manual

Q:When i waa replacing the valves in the las 4 valves , they dropped and i dont know how to make them go back up, and i dont want to take the engine out of the car, is there any tool to make the valve go back up or there is any way to do it?? People told me that i can crank it by and , but i dont know how to do it where do i have to do it, i need help please im begging for help!

You could use a socket and breaker bar on the bolt on the end of the crankshaft to slowly and carefully rotate the engine by hand. But if the valve is all the way down into the cylinder, the only fix is to remove the cylinder head. If you have been asking for days, maybe, just maybe, you are in over your head. Bring the car to a reputable mechanic and pay to have it repaired. Repeating the same question obviously isn't helping at all. All you are accomplishing is to irritate the people here on Yahoo Answers.

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:Butterfly valve use

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. Industrial butterfly valve features, capable of high temperature, applicable pressure range is higher, the valve nominal diameter is large, the valve made of carbon steel, the valve plate sealing ring using metal rings instead of rubber rings. Large high temperature butterfly valve welded by steel plate, mainly used for high temperature smoke duct and gas pipe

Q:The water supply pipe is the gate valve And on the cross dry pipe are the gate valve? To answer the 30

Crown valve pressThere is no standard answer to this question. I can only give you my personal opinionRiser butterfly valve is generally place in these places (the pump outlet valve, drainage system, upper and lower floors) riser are basically installed butterfly valve, butterfly valve is not cheap, fast speed is fast closing butterfly valve can be quickly closed and open educationYou see the water pipe installed valve (with all the cross tube is the basic gate) explanation, because in contrast to the quality and stability, the valve will be better, the site does not need fast switching, it will choose good stability point gateSum upThe drains are all butterfly valves, and the stabilizing pipes are all valves! (do not rule out a full use butterfly valve for stealing work)

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:Transformer butterfly valve and pressure relief valve difference

The butterfly valve is usually fitted with an oil immersed transformer between the tank and the radiator to control the flow of oil between the transformer tank and the heat sink. When large power transformers are delivered, the radiators are usually individually packed to reduce transport sizes. The butterfly valve is closed to prevent the outside air or water from entering the transformer tank. When the transformer is transported to the installation site, the radiator is installed on the butterfly valve one by one. When the radiator is installed, the butterfly valve can be opened so that the oil flow between the transformer, the oil tank and the radiator can be circulated, so as to play the role of heat dissipation.When the transformer is running, it is found that when the radiator has seepage, the butterfly valve can be closed to avoid further leakage of transformer oil, and a new radiator can be replaced.

Q:Does the pneumatic butterfly valve need electricity?

Are pneumatic, and directly rely on gas control, the most important thing is that the gas, then certainly have to take control of electricity!
