A swing check valve 20 suitable for use in an aircraft fuel system, such as a fuel pump, has a valve body 30, a hinge member 40, and a compliant seal member 50; the body and the seal are formed in a multi-material injection moulding process (MMM). The seal may be co-moulded over an annular recess formed between two spaced apart projections 33, 34 on a body sealing face 32, which faces a valve seat in use, the seal extending around a peripheral portion of the body. The hinge member may be formed from a metal, such as aluminium, and attached to the body by an intermediate snap fit connector (fig.2B,60). The body may be polyether ether ketone (PEEK).
