Abstract

A valve comprising a housing, a flow guide comprising an operational axis, a poppet comprising a sealing surface, a bias weight and a reaction force component engaged with the poppet. In a first orientation, the poppet is open, and in a second orientation, the poppet is closed. The flow guide comprises a first side opposite a second side, and a through hole extending between the sides. The through hole adapted to provide fluid communication through the flow guide. In the open position, the sealing surface is offset from and permits flow through the flow guide. In the closed position, the sealing surface is engaged with and prevents flow through the flow guide. The bias weight may exert an opening bias force on the poppet that is a function of the orientation of the operational axis. The reaction force component may exert a closing bias force on the poppet.
