Abstract
A laminar flow control valve having a unitary housing, wherein the valve housing is coupled to a housing for an electrically powered solenoid device. The poppet is loosely secured to the valve stem by use of a magnet, which permits lateral movement between the poppet and the valve stem. In the preferred embodiment, a hemispherical poppet is mounted to the stem of the operating mechanism by a magnet which is fixedly secured to the stem, permitting lateral movement of the poppet to ensure self-alignment with the valve seat upon closing of the valve. An alternative embodiment utilizes conical surfaces of the valve seat and poppet.
