Zusammenfassung:	A dispenser for dispensing foamable compositions includes a first module comprising a first housing, a fluid flow fitting in the first housing, a shutoff valve in the first housing and in fluid communication with the fluid flow fitting. The dispenser further includes a second module comprising: a second housing, a valving chamber in the second housing for receiving fluid from the shutoff valve and the fluid flow fitting; and an attachment for securing the first and second modules to one another with the valving chamber in fluid communication with the shutoff valve and the fluid flow fitting so that foam precursors can travel from the foam fittings to the valving chamber, and be dispensed from the chamber to form foam.
