A fluid control valve (10) comprising: a fluid carrying core (12) and separatable magnetic field generating portion (14). The fluid carrying core (12) comprises: a magnetic armature (30) movable through a working gap (32) within a thin walled tube (34). The armature includes a first plurality of grooves (100) to permit fluid flow thereacross. The tube is joined to a magnetic first member (50) in a manner to form a leak-free seal (56) generally at one end of the tube. A second member (80) partially seals the other end of the tube and includes second flow means a second plurality of axial grooves (84) for receiving fluid carried to the valve (10) and for communicating same with the armature (30). Various passages are provided to carry fluid to and from the valve. The position and number of passages permit the valve to be used as a two-way valve or as a three-way valve passage means (88;64) for transporting fluid away from the valve (10).
