1. An actuator component configured to cooperate with a housing to form a valve, the actuator component comprising:
a carrier attachable to the housing, wherein the carrier is of elongated shape having an upper surface and a bottom surface,
a plunger arranged on the carrier and comprising a sealing surface arranged at a top end of the plunger,
a shape memory alloy actuator arranged co-linearly with the plunger between the carrier and the plunger and configured to exert an actuation force onto the plunger, and
a spring co-linearly arranged with the plunger between the carrier and the plunger and configured to exert a bias force onto the plunger, wherein the plunger, the shape memory alloy actuator, and the spring extend along the upper surface the carrier, and
an elastic member extending away from the upper surface of the carrier and configured to engage with a top plate of the housing to press the carrier against a bottom plate of the housing.
