Abstract

A poppet valve (100) is provided according to the invention. The poppet valve (100) includes an actuator (120) including a pivoting armature (127) comprising a first end (105) and a second end (106). The pivoting armature (127) pivots at the first end (105). The poppet valve (100) further includes a tension connector member (129) connected to the pivoting armature (127) away from the first end (105) and a valve poppet (135) connected to the tension connector member (129). The pivoting armature (127) lifts the valve poppet (135) away from a valve orifice (110) via the tension connector member (129) when the actuator (120) is activated.
