A valve (100) comprises a housing (111) having a first fluid port (121) and a second fluid port (122). An actuator component (601) comprises a carrier (621), a plunger (125) having a sealing surface (125-3), a shape memory alloy actuator (151) arranged co-linearly with the plunger (125) between the carrier (621) and the plunger (125) for exerting an actuation force onto the plunger (125), and a spring (161) co-linearly arranged with the plunger (125) for exerting a bias force onto the plunger (125). The actuator component (601) is arranged such that the sealing surface (125-3) of the plunger (125) can sealingly engage the first fluid port (121). The actuator component (601) is arranged in a flow path in-between the first fluid port (121) and the second fluid port (122). A circuit board (631) provides an electrical current to actuate the shape memory alloy actuator (151). The housing (111) is at least partly arranged between the circuit board (631) and the carrier (621) and comprises through holes (615) for electrical pins of the actuator component (601). The valve (100) may be used to provide in a modular valve system (800.
