An emergency release system for a fluid transfer system having a first valve and a second valve that is selectively fluidly coupled to the first valve, the emergency release system comprising: a breakaway coupler mechanism engageable with the first valve and the second valve to releasably couple the first valve and the second valve together, the breakaway coupler mechanism including a first clamp member engaged with the first and second valves (54, 56), the first clamp member having a first end and a second end; and a second clamp member engaged with the first and second valves (54, 56), the second clamp member having a first end coupled to the first end of the first clamp member and a second end, and a gate, that is releasably coupled to the second end of the first clamp member and the second end of the second clamp member and that retains the breakaway coupler mechanism on the first valve and the second valve when the gate is positioned in a locked position, in which the gate is coupled to the second end of the first clamp member and the second end of the second clamp member; an actuator mechanism engageable with the first valve and the second valve, the actuator mechanism including a gate actuator and a safety plate, the gate actuator configured to engage the gate of the breakaway coupler mechanism as the actuator mechanism moves from a connected state to a disconnected state, and the safety plate being positioned adjacent to the gate when the actuator mechanism is in the connected state to prevent an inadvertent actuation of the gate out of the locked position; and a piston-cylinder assembly configured to engage the actuator mechanism to selectively and simultaneously close the first and second valves (54, 56), and to disengage the breakaway coupler mechanism from the first valve and the second valve. a breakaway coupler mechanism engageable with the first valve and the second valve to releasably couple the first valve and the second valve together, the breakaway coupler mechanism including a first clamp member engaged with the first and second valves (54, 56), the first clamp member having a first end and a second end; and a second clamp member engaged with the first and second valves (54, 56), the second clamp member having a first end coupled to the first end of the first clamp member and a second end, and a gate, that is releasably coupled to the second end of the first clamp member and the second end of the second clamp member and that retains the breakaway coupler mechanism on the first valve and the second valve when the gate is positioned in a locked position, in which the gate is coupled to the second end of the first clamp member and the second end of the second clamp member; a first clamp member engaged with the first and second valves (54, 56), the first clamp member having a first end and a second end; and a second clamp member engaged with the first and second valves (54, 56), the second clamp member having a first end coupled to the first end of the first clamp member and a second end, and a gate, that is releasably coupled to the second end of the first clamp member and the second end of the second clamp member and that retains the breakaway coupler mechanism on the first valve and the second valve when the gate is positioned in a locked position, in which the gate is coupled to the second end of the first clamp member and the second end of the second clamp member; an actuator mechanism engageable with the first valve and the second valve, the actuator mechanism including a gate actuator and a safety plate, the gate actuator configured to engage the gate of the breakaway coupler mechanism as the actuator mechanism moves from a connected state to a disconnected state, and the safety plate being positioned adjacent to the gate when the actuator mechanism is in the connected state to prevent an inadvertent actuation of the gate out of the locked position; and a piston-cylinder assembly configured to engage the actuator mechanism to selectively and simultaneously close the first and second valves (54, 56), and to disengage the breakaway coupler mechanism from the first valve and the second valve.
