The valves have their orifices so dimensioned that the flow rate from each valve is weighted according to the weighting of the electric signal controlling it. Each valve has a fluid flow path including a main orifice and a control orifice. The main orifice, which is closed or open according to the position of a movable sealing plug, has a substantially larger cross-sectional area than does the control orifice. The area of the control orifice is adjustable to determine the flow rate when the main orifice is open. The control orifice is the annular area between the walls of a cone-like needle valve member 41, Fig. 6, and a cylindrical duct 36. The axial position of the valve member 41 is adjustable by movement of a set screw 40 integral with one end of the valve member. Fluid flowing in the valve passes through the control orifice and passes through duct 26 to the main orifice which is normally sealed by a resilient plug 52, Fig. 5. The plug is mounted in the end of a slug 51 which is made of magnetic material. and is spring-urged axially towards duct 26. The slug 51 is surrounded by a solenoid which when energized moves the slug away from duct 26 to open the fluid flow path, fluid passing via annular groove 30 to exit duct 46. The modular assembly has common supply and outlet ducts connected to ducts 36 and 46 respectively of each valve, and has a central recess for the electric supply terminals. A number of the valve assemblies may be combined for the selective mixing of a number of fluids.
