Abstract
A pressure relief valve including a valve seat and a valve seat retainer abutting the valve seat. The valve seat has a central channel whereas the valve seat retainer has a number of peripheral channels. A deformable plug is positioned between the valve seat and the valve seat retainer. The deformable plug has a head abutting the valve seat and normally blocking the central channel and a tail abutting the valve seat retainer at a location between the peripheral channels. The tail deforms upon receiving a predetermined load from the head thereby permitting the head to unblock the central channel and open the pressure relief valve.
