SMC is your friend. You can often find good industrial surplus SMC pneumatic components on sale on eBay that will probably still last halfway to the entropic heat death of the universe. There are also apparently SMC components that are made in China for the Chinese market (same good stuff) that are sold on FleaBay and Amazon in other markets at prices comparable to the lesser industrial brands. I've had good luck with both for common stuff like an FRG (filter, regulator, gauge), small commodity air cylinders and common commodity solenoid valves.
Like seemingly everything else, there are probably cheap clones of SMC parts that are junk. Caveat emptor. It's your luck that's what you'll likely buy on eBay, Gene. :-/ On 2/15/19 9:02 PM, Gene Heskett wrote: > On Friday 15 February 2019 20:33:44 andy pugh wrote: > >> On Sat, 16 Feb 2019 at 01:07, Gene Heskett <[email protected]> > wrote: >>> But, if I turn that 6 amps times 12 volts into watts=72, no way in >>> hell would that survive a 1 hour run time gcode program. >> Why do you assume that? >> >> (and what do you have to lose by testing the assumption?) > A: From the size of the coil Andy, 72 watts of heat would let ALL the > smoke out in 15 minutes or less, Its sold as an air horn valve with an > expected duty cycle of <5%, and > > B: I don't have a 12 volt, >80 watt psu to do the smoke test with. > > C: I'd druther not test my fire insurance. > > D: I just bought that Chinese airtec as I can probably regulate the input > pressure to below its 0.8MPa ratings.
