A valve includes a housing with a bottom plate, first and second fluid ports, and an actuator component arranged such that the bottom plate engages the actuator component. The actuator component includes a carrier, a plunger arranged on the carrier and comprising a sealing surface, a shape memory alloy actuator arranged co-linearly with the plunger between the carrier and the plunger to exert an actuation force onto the plunger, and a spring co-linearly arranged with the plunger between the carrier and the plunger to exert a bias force onto the plunger. The sealing surface of the plunger can sealingly engage the first fluid port. The valve further includes a circuit board comprising circuitry to actuate the shape memory alloy actuator. The housing is at least partly arranged between the circuit board and carrier and comprises through holes to receive electrical pins of the actuator component extending towards the circuit board.
