Q:How do hydraulic butterfly valves work?

The valve hydraulic device is mounted on the valve drive shaft. The driving shaft of the valve is fixed with a transmission spline, and the crank (with an outer spline) is sleeved on the driving shaft. When the hydraulic system works normally, through the gear sleeve, the transmission spline is connected with the crank. Thus, the hydraulic cylinder drives the crank, and the spline on the crank passes the torque to the transmission spline by means of a gear sleeve. Because the driving spline is fixed on the driving shaft, the driving shaft rotates and drives the valve plate to start and close. Sorry, the picture doesn't come up

Q:I was wondering if someone could tell me the manufacturing date on this aircraft engine valve.

Wow Hannah! That's a cool find for sure! It appears to be possibly a valve for a radial aircraft engine as it looks very similar to ones i've seen used in Pratt+Whitney R3350's etc. It looks like it could probably date to the 1940's up thru the 1950's. Look for a Part Number stamped on the valve or on the box. After WW2 there were all kinds of manufacturers making parts for airplanes. Many were gobbled up by competitors, converted to manufacturing other products or went out of business altogether. However, a few did hang on....and I think this may be what has become of Thompson Aircraft today.... Thompson Aerospace, Inc 22431 Antonio Parkway B160-102 Rcho Sta Marg, CA 92688-2804

Q:Butterfly valve model D373F-16C, ask God answers

D butterfly valve, 3 turbo rotating, 7 pairs clip type, 3 eccentric F PTFE seal, 16 nominal pressure 1.6MPA, C valve body material, carbon steel

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 do D71, D371 and D341 represent in butterfly valves?

D71 stands for middle line to clip butterfly valveD371 represents the worm wheel centerline pair clip butterfly valveD341 stands for worm gear flange butterfly valve

Q:What are single eccentric and double eccentric in butterfly valves? What's the difference, please explain in detail?

Eccentric butterfly valve is divided into single eccentric butterfly valve, double eccentric butterfly valve, three eccentric butterfly valve, variable eccentric butterfly valve.Single eccentric butterfly valve: extrusion problems, address concentric butterfly valve and valve seat of the resulting in a single eccentric butterfly valve, the structural characteristics of the stem axis deviated from the disc center, so that the butterfly is no longer a rotary bottom plate, axial dispersion, reduce the excessive squeezing and the lower end of the seat of the butterfly board.

Q:What's the difference between a clip on handle butterfly valve and a turbo butterfly valve? Where are they used?

Depending on the size of the valve and the opening and closing torque, the transmission mode is different (handle or turbine).
