HELLO EVERYONE,

SO BASICLY WE WANT TO SIZE A PRESURE EQUALIZATION LINE FOR A 10" PIPELINE VALVE (KIND OF BY-PASS) TO EQUALIZE THE DOWNSTREAM OF THE 10" VALVE DE TO A VERY HIGH DP BETWEEN UPSTREAM AND DOWNSREAM OF THE VALVE.

THE PIPELINE CARRY A 85 BAR LPG.

I suggest using high pressure tubing similar to the tubing routed to the valve actuator.
