Would CSA B51 cover a 1/4" air solenoid valve????? 2

[Hydguy100]

Hi everyone, I have a question, Would CSA B51 cover a 1/4" air solenoid valve operating at 120psi??? Are these type of valves required to be registered for a CRN?

I have a customer at a power plant that is jumping up and down saying that all of his valves now require a CRN or registation under ABSA. And that all pneumatic components have to have CRN's now, I told him that will pretty much shut down pneumatic sales in the country because very few components used at shop air have CRN's.
Please help.

Thanks,

Hydguy.

In a word, the answer is almost certainly no.

Most of the provincial Acts that enable CSA B51 (i.e. give it the power of regulation) give specific exemption for compressed air components/systems below 3/4" attached by means other than welding. Your 1/4" solenoid valve would therefore be exempt. But you'd need to read the Alberta Boilers and Pressure Vessels Act and its associated regulation to be sure.

we do piping for ABSA and moltenmetal's comment above is correct. systems below 3/4" are exempt.

May I recommend calling ABSA and having them confirm for you? Googling ABSA brought up contact information.

While I certainly agree with both moltenmetal and regrumble, your customer would probably be more satisfied with "I spoke to ABSA and their representative -- name inserted here -- told me that components below 3/4" were not covered. Here's ABSA's number if you want to check ..." then with "these anonymous people on this website told me that it was ok. I don't know who they are, or what their backgrounds are, but I read it on the Internet, so it must be fine."

Thanks Everyone, I did call ABSA yesterday and received almost the same answer, they said that in Alberta its everything under DIN50 or 2". Thanks for the help folks.

Apologies for hi-jacking your post, but could I ask whether this would cover hydraulic valves as well as pneumatic?

 

[vpl]

Yes, but again, calling ABSA is the best way to get a definitive answer that you can quote.
