Thank You for the tips .. 1) We have tried to increase groove depth, and it looks that this helps a little. Groove width is not possible to change. 2) There is no any regulation of flow. Gas is geting out od cilinder at 8 to 15 bar without any resistance (that is condition) 3) Yes, spacer...

I think that is not possible to upload files here, so I created FTP account, and picture can be found here: http://snapyy2002.freewebsitehosting.com/Valve%20ilustrated.jpg 1) I know that O ring design is not best solution, but I have to maintinance those old valves .. If I colud make some not...

Thank You all for reply's. Great links, I have found a lot of info on various things .. great, great stuff .. Calculations for O rings is not realy what I searching for. I would like to see some cross section's of various 5/3 valves, and specialy 5/3 valve with O rings. Sorry if I'm bugging...

To Atad: Yes, it's possible that I use this valve outside it's default parameters regarding speed of gas flowing through it. Regarding direction of flow, there should not be the problem IMHO. Even if flow is too fast I have to do something to make those valves work. So It would be best if I have...

I have few 5/3 manual valves (1/2" connection) that give me problems with inside "O" rings. When there is fast circulation of air through valve, O ring's are sucked out of their positions. That is problem with few out of 15 valves. Others work ok with same conditions. I hope that...

Hi everyone .. Can You tell me real name of GERMAN GAS HANDBOOK. I'm not sure if it realy exits, or maybe ther is more than one. Can You please, specify name and author of those, and www link or e-mail where I can get it. Thank You in advance ..

Tnx for reply .. but is there any cheeper solution .. I need just for few parts in cca 1 year ..

How can I determine natural frequency of some part (or assembly) that is made in SolidWorks? What do I need, some FEA package or something simpler ?

So, once you buy SW then you get all new versions of SW ?

In short; Is it worth waiting for SolidWorks 2002, or is better to get SolidWorks 2001+ now ? Is SW 2001+ only version between 2001 and 2002, or is it some package with advanced functions that come only in "+" version's ? When SW 2002 should came out ?

(maybe for another thread) Where to get some "true Involutes gears" ? Only for non-commercial trial purpurose .. Tnx ..

What about ATI Radeon ? Little offtopic: 1. Can dual display (output on 2 monitors) be useful in application like SW ? 2. Is it better to have lot of RAM on graphic card if I don't use any textures ? How much is enough for res. 1280x1024 in 32bit color ?

Maybe You using older version of MS Office that is not compatibile with SW ... Just guesing ...

Ok, .. look's like I'm going to solve this with macro from within Excell, maybe even print whole BOM page from Excell, and use SW BOM command just to generate contest of table. Tnx...

Some servers are faster then other. Here I get under 3 Kb/sec, so i searched for faster download. I'l try to call auth. reseller.

I have tryed to adjust BOM for one of the company that intedet to use S.W. in the future. They have standard that main assembly drawing is on first sheet of paper and the BOM is on second paper. So I run it some problem's; 1. How to put BOM on sheet other than source drawing ? I can put drawing...

What site is it ? Official (SW site) or some other ? Tnx. PS: Sorry on bad english ...

Look at this freeware program "WinTopo" at http://WinTopo.com. It read's bitmap images, trace them and save in varios vector files (like AutoCAD dxf). Works just fine ...

1. Add, substract, etc .. of bodies (like in Mechanical Desktop). I know for "Join", but how to substract (cut) one body or part from another. Is there some other command other then those for molding ? Something simple ... 2. Split part, so i get 2 or more parts from one. I can use...
