Abstract
A valve apparatus that includes a valve assembly including a valve retainer body that houses a movable poppet that defines a valve member that is configured to contact a conically shaped valve seat of the valve retainer body; and a motor assembly including a rotatable shaft that is configured to actuate the valve assembly; wherein the rotatable shaft includes a thread formed at an end thereof, the thread being engaged with a sleeve that through rotation of the thread by the rotatable shaft will translate the sleeve towards and away from the movable poppet to transfer an axial force to the poppet that forces the valve member into engagement and disengagement with the valve seat to open and close the valve assembly.
