As title says, I am going to build my own CO2 system, but I found out that the Clippard is not as good as before. I was thinking to order a Burkert 6011 with Buna-N seals, so I sent a email to the guy, and never get a reply. I am thinking what kind of solenoid are you guys using? THX
I use clippards. I had one fail after a couple of years but I mangled when I put it on the first time and with every adjustment it only got worse. I cant really blame them for the problem and I have been happy with the others I have had for awhile.
I had a clippard go bad so I replaced it with a Parker that I got off of Ebay. The Parker is much better in my opinion, it doesn't stick open and it's stainless steel, not cast aluminum. I have heard of people having the coils burn up on the Parkers but, I haven't had any issue yet. The Burketts so far, have a better track record than both the ones just mentioned. I would look on the barr report for alternate sources for the Burkett.
Clippard solenoids have not changed at all. It is a myth. In industrial use, the fail rate for Clippard solenoids is extremely good. I am not sure why there appears to be so many problems with them in aquarium use. I personally haven't had any problems. How ever the Burkarts probably are a better solenoid.
Clippard also has a non-piston solenoid if you want to avoid the problems of piston based solenoids. But they have smaller fittings.
