What symbol is this? (P&ID)

What symbol is this? (P&ID)

(OP)
Hi all, I was looking over a P&ID and am not familiar with the highlighted symbols below. Would anyone be able to help identify them? The horizontal line is headed towards a cartridge filter and the vertical branch is a bypass, if that context helps. I presume they must be some sort of valve, as there is nothing else shown on the line entering the cartridge filter.
