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: Model specification for butterfly valves: Various classifications of butterfly valves1. classification by structure:(1) Central sealed butterfly valve(2) single eccentric sealed coal valve;(3) double eccentric sealed butterfly valve(4) three eccentric sealed stamp valve;

Q: The flow ratio of area and maximum flow area of the valve is? If it refers to the opening of the valve rotation angle? Butterfly linear closure refers to the butterfly valve at constant angular velocity close? When the change trend of flow is what? These valves problem bothering me for a long time,: Butterfly valve "opening - flow" curve in the flow of 25%-75%, that section is basically linear. That is, the opening of 40%, that flow is about 40%Butterfly valve opening degree of 0.5, should be opened 50%, that is, opening to 45 degrees;

Q: What does the butterfly valve model d344h, d345h, d346h, d347h mean?: According to the international standard of the letters and numbers apart to explain D344H D is a unit of butterfly valve, two unit 3 is driving mode: turbine, three unit 4 connection: flange connection, four unit 4 Structure: seal type linkage, five unit H sealing material: Cr13 stainless steelD345H compare yourself to the above. Unit 5 four is a sealed, single eccentric structureD346H four unit 6 is an unsealed center vertical plateD347H four unit 7 is unsealed double eccentricIn general, there is only one difference between them: the structural form is different!

Q: Where are the exhaust valves, mud valves and butterfly valves?: Chemical plant with colloid, puffed agent and granule. Wine industry, paper industry. Butterfly valves are used in petroleum, chemical, food, pharmaceutical, textile, water and electricity, ships, urban water supply and drainage, smelting, and energy systems as regulating and intercepting devices.

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: CAD drawing of butterfly valve: Your question is very international. Ha-haThis method of painting is not clear in one or two words.First you'll know the map, then you'll use CAD, so the two will add up.Guess you will.

Q: What is the D37-10Q butterfly valve?: D- butterfly valve (valve type); 3- worm (drive); 7- pairs of clamp (connection); 10-PN1; nominal pressure of 10 kg; Q- ductile iron (valve body material).
