In the absence of a legend sheet looks like a shittily drawn reducer. Or check valve.
This is what legend sheets are for.
26 u/Afghanman26 Nov 15 '24 Haha, tell that to GSK I was thinking a check valve, but the symbols were throwing me off. Appreciate the help 28 u/djcrackpipe Nov 15 '24 This is definitely a check valve to me 8 u/TheScotchEngineer Nov 15 '24 Probably check valve - one of the valve with the most variation in styles. Though if using this style (triangle leading into a line), normally the length of the symbol is stretched to a 'standard valve' length. 3 u/letsburn00 Nov 15 '24 It's absolutely a check valve. That's the only symbol I've ever seen used for a check valve. 1 u/verticalfuzz Nov 27 '24 I have typically seen a circle in a wedge, like this, ·>, to indicate a checkball and seat. 1 u/letsburn00 Nov 27 '24 That looks a bit like a dual plate check valve. Often I just see the generic symbol. 1 u/verticalfuzz Nov 27 '24 Is there a handy reference? 1 u/TRGoCPftF Nov 17 '24 If you mean GSK the pharma company, it’s reassuring to know poorly fucking identified P&IDs are just an industry standard 🤣
