1. An automatic fire extinguisher (AFE) valve assembly, comprising:
a valve body; a push rod defining an angled face and disposed in the valve body; a poppet stem arranged perpendicular to a longitudinal axis of the push rod, disposed in the valve body and continuously contacting the angled face of the lush rod to in maintaining a closed position of the assembly, apply a continuous force to the push rod in a direction opposite a force applied to the push rod by an actuator of the automatic fire extinguisher; a poppet-to-valve-body seal coupled to the poppet stem and disposed in the valve body; and a poppet-return spring coupled to the poppet stem and disposed in the valve body, wherein the push rod is configured to force the poppet stem toward a cylinder of the automatic fire extinguisher to open the poppet-to-valve-body seal for creating fluid communication between the cylinder and a main outlet of the assembly, allowing extinguishing agent from the cylinder to flow from the main outlet.
