Q: What do you mean, handle, butterfly valve, hard back and soft back?
My understanding is: PTFE butterfly valve is a hard back; soft rubber seat is a soft back
Q: The difference between butterfly valve d71x_10s and d341s-10
Before distinguishing between the two, you must first read the identification of the valve type:D stands for butterfly valves,3 means that the worm gear is connected and the drive does not indicate the handle7 and 4 indicate pipe to clamp connection, pipe flange connection, respectively1 means single eccentric, that is, the stem is not in the center of the butterfly plateThe former S indicates the material name of the valve body - plastic, X means sealing and the lining material is rubberThe latter S indicates the sealing lining material code ---- plastic, and the valve body is cast iron.10 means stress.
Q: I want to switch off the water in the bathroom only due to replacing sink taps, will water still come out of the pipe if i turn the stop valve
Assuming that the stop valves are good, turning them off will stop the flow of water to the sink taps. To test them, turn on the water faucet at the sink, then turn off both stop valves. The water should stop coming out of the faucet. If it continues to drip, the stop valves are defective and should be replaced when you do the job. If this is the case you'll have to shut off the main water valve or a valve upstream of the stops to replace them. Good Luck
Q: How do you draw the butterfly valve in the engineering drawing?

Q: What's the difference between a clip type turbine butterfly valve and a flanged turbine butterfly valve?
For clip butterfly valves, there are no flanges at the ends of the butterfly valve. There are only a few guide bolts. The valve is connected with the end flange with a set of bolts / nuts.In contrast, the demolition to facilitate some of the lower cost of the valve, but the drawback is that a sealing surface problems, the two sealing surfaces have to be taken apart.Flange butterfly valve at both ends of the flange, and pipe flange connection. The seal is relatively more reliable, but the valve is of relatively high cost.
Q: I went online to check where was the pcv valve for a 2001 ford focus, but I didn't find it. Does anyone have a picture? Thanks
Go around to the passenger side of the car and shove your arm way down along the firewall behind the engine. Feel around with your fingers and you will feel the PCV hose where it connects to the intake. Once you have found that you can follow it forward from underneath (no kidding) about a foot to the PCV valve. I don't think it is even visible from the top.
Q: Gate valve, butterfly valve and so on can do the valve so that?
Valve can not be used to adjust the use, if the switch can not be in place, the medium flushing gate valve is easy to cause poor sealing!
Q: What does "D41X-16" mean?
D butterfly valve, 41 flange connection, X rubber seal, 16 kg pressure
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.
