Automated bleed-off system for a fluid system

A bleed-off manifold for a hydraulic fracturing system, comprising:

• a first fluid input to receive pressurized fluid from a pump side of the hydraulic fracturing system,
• wherein the pump side is upstream of a valve, in a conduit of the hydraulic fracturing system, that is between one or more pumps and one or more wells of the hydraulic fracturing system;
• a second fluid input to receive pressurized fluid from a well side of the hydraulic fracturing system,
• wherein the well side is downstream of the valve;
• a bleed-off line fluidly coupling the first fluid input and the second fluid input to an output,
• wherein the bleed-off line comprises a multi-stage choke assembly;
• a bypass line fluidly coupling the first fluid input and the second fluid input to the output,
• wherein the bypass line bypasses the multi-stage choke assembly;
• a first isolation valve to control flow through the first fluid input;
• a second isolation valve to control flow through the second fluid input;
• a third isolation valve to control flow through the bleed-off line;
• and
• a fourth isolation valve to control flow through the bypass line.
