Is BOV connected to "main circuit", i.e. can be fed from either on- or offboard gas?
Hello Dragan,
The offboard will feed all system i.e. Manual Feed, ADV & BOV for DIL and Manual Feed & Solenoid for the O2 side.
The only issue with BOV is the fact that the Sentinel & Boris use QC4 Swagelok for offboard connection, which acts as a flow restrictor. The BOV is only to be used as a sanity breathe in other words 1-2 breathe before you switch to external bailout. You will have to experience the flow restriction at different depth, it obviously depends on the mix you are using.
On my Boris I am using Swagelok QC6 for the offboard, it has a bigger flow!
Cheers
