System for multiple pressure relief device activation

A system including a first valve and a second valve, the first valve fluidly connected to a first vessel and the second valve fluidly connected to a second vessel, the system comprising:

• the first valve including:
• a body including:
• a bore;
• a first port in fluid communication with the bore and an interior of the first vessel;
• and
• a second port in fluid communication with the bore, in fluid communication with the second valve, and in fluid communication with an atmosphere exterior to the first vessel;
• and
• a piston movably disposed within the bore, wherein:
• a first position of the piston blocks the first port;
• and
• a second position of the piston allows fluid communication between the first port and the second port;
• and
• a trigger conduit through which fluid pressure from the second valve is capable of being communicated to the second port, thereby urging the piston to the second position.
