Q:Butterfly valve D71X-10 and butterfly D371X-10 what is the difference?
One is the turbine drive and the other is with the handle
Q:Which is expensive, butterfly valve?
The same material and caliber, butterfly valve structure is simple, less wood, the price is much lower than the gate valve, especially for clip type butterfly valve.
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:1 valve bugle fingering chart? (more complicated than it sounds)?
Starting below the staff in treble clef - G - open (yeah, intonation heck) C - open D - valve (gap) F# - rotor G - open or valve (gap) Bb - Rotor valve B - Rotor OR valve (pick it) C - open C# - both D - valve D#(Eb) - rotor E - open F - valve F# - rotor G - open G#(Ab) - both (yech!) A - valve or rotor Bb - open or both B - valve or rotor C - open anything above C - dial it in. After seeing this, you'll know why going from G-D to G-F was such a radical improvement. After playing on this relic, you'll really appreciate what some of those corps had to do to sound good.
Q:What is the butterfly valve
Conclusion: Although the double valve advanced technology, metrology, but must ensure stable and timely flow of materials, in order to achieve good results, so the combination of flotation system and dual use of butterfly valve can fundamentally solve the flow and measurement of powder, so as to rely on self weight principle of materials, so we plant layout the middle of a large number of mechanical equipment to save not only, more important to reduce the cost of investment and running.
Q:butterfly valves d7a1x5
D- valve type (butterfly valve), 7- connection mode (to clamp), A- valve shape mode (A), 1- structure form (vertical plate), X5- valve seat sealant species (Ding Qing, NBR)
Q:What is a Valve Adjustment?
Adjusting hydraulic lifters, also called setting the valve lash provides the necessary travel and operation for the opening and closing of the intake and exhaust valves. Most new vehicles use hydraulic lifters, since their operation and design provides an easy and simple method of keeping the valve train in synchronization. You can perform the adjustment with a cold, static engine or during engine idle once the operating temperature has been reached. Adjusting the lifters on a running engine, however, can present a problem with oil splashing upward from the tappets. They make a spring clip to prevent it from getting all over the engine and compartment. Cost vary from city to city Mechanic to mechanic Hope it helps Lr
Q:Butterfly valve D71X-1.6C, DN50, there is no difference between C and no C? What do you mean by "concrete"?
Front is the same, there is C refers to the body of the material is carbon steel, without C, usually refers to gray iron (cast iron is more common, so are generally omitted)
Q:unstick valves in 1988 volkswagon rabbit?
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.
