A device is disclosed for receiving fluid components from a proportioning device and delivering the components to a mixing tube for chemical reaction of the components. The device comprises a housing having two inlet chambers and an outlet chamber. One of the fluids is connected to the first inlet chamber while the other fluid is connected to the second inlet chamber and both inlet chambers are fluidly connected to the outlet chamber by separate fluid passageways. A valve assembly is operable to simultaneously open both fluid passageways so that the fluids from the inlet chambers flow into the outlet chamber and then out from the device housing to the mixing tube. The device housing comprises two housing parts which are detachably secured together and, when separated, provide open access to the valve members and outlet chamber for cleaning and to enable a ratio check to be performed at a point in the system close to the mixing tube.
