Abstract
A coil assembly housing for housing the actuator of a stepper motor valve includes a snap feature for snap fitting the coil assembly housing to a valve house assembly, wherein the snap feature includes at least one protrusion pointing radially inward of the coil assembly housing, wherein the protrusion is provided for interacting with a recess of the valve house assembly, and wherein the protrusion is held inside the recess by a wall of a valve block, into which the valve house assembly and the snap feature are insertable. The disclosure also pertains to a valve house assembly, a valve block and a stepper motor valve having such components.
