A shaped memory alloy (SMA) valve assembly includes a plurality of SMA valves and a main printed circuit board carrying electronic components and conductors for operating the SMA valves. Each SMA valve includes a pressure chamber having a port. Each pressure chamber contains a valve element biased to a rest position in sealing abutment on a valve seat of the port, a SMA actuator, and an actuator printed circuit board for mounting and electrically connecting the SMA actuator. Each actuator printed circuit board portion is connected to the main printed circuit board portion by a bridge printed circuit board portion, and each pressure chamber has an opening to allow a respective bridge printed circuit board portion to extend therethrough. The opening is provided with a pocket filled with cured sealing glue to embed the bridge printed circuit board portion extending therethrough and to seal the opening of the pressure chamber.
