A pressure relief valve includes a valve body having a main bore, an inlet bore which is connected to the main bore, an outlet bore which extends through a side of the valve body, and a valve bore which connects the inlet bore with the outlet bore. A valve member is positioned in the valve bore and is movable between a closed position in which a fluid in the inlet bore is prevented from flowing into the outlet bore and an open position in which the fluid in the inlet bore is permitted to flow into the outlet bore. The valve member is movable from the closed position to the open position in response to an overpressure event in the main bore. The valve body further includes a return bore which connects the inlet bore with the main bore.
