Abstract: Various examples relate to electrically actuated valves. Various examples relate to actuators to be used for valves, e.g., shape—memory alloy actuators or solenoid actuators (151) or piezoelectric actuators. Various examples relate to a modular concept in which a valve can be formed by attaching an actuator component (601) to a housing. Various examples relate to a further modular concept in which multiple valve blocks, each valve block including one or more valves, can be fluidly coupled with each other.

Abstract: A fluid valve module (10), a fluid valve system (20) and methods (30A, 30B) of producing the same are provided. The fluid valve module (10) comprises a housing and a plurality of valve members (103). The housing comprises a housing body (101) and a housing cover (108). The housing body (101) comprises a fluid feed partition (104), a plurality of valve body partitions (105), and a plurality of valve ports (106). The housing body (101) further comprises wall openings (107) between an interior of the fluid feed partition (104) and an exterior of the housing body (101). The valve body partitions (105) are each shaped for mating with the housing cover (108) in a fluid-tight manner, and are each in fluid communication with the fluid feed partition (104) and at least one of the valve ports (106).

Abstract: A valve (100) includes a housing (111) and the fluid port (121). A plunger (125) is configured to seal the fluid port (121) in a first position (91) and to unseal the fluid port (121) in a second position and to displace along a displacement direction (259) from its first position (91) towards its second position. The valve (100) also includes at least one shape memory alloy, SMA, actuator (151, 152) extending along the displacement direction (259) for at least 50% of its length and configured to exert an actuation force (155) on the plunger (125) to displace the plunger (125) from the first position (91) towards the second position.
